Losing its leaves in winter, the confederate rose is no rose but instead a member of the hibiscus family. Hibiscus mutabilis matures at up to 15 feet tall and 10 feet wide if never pruned or killed back by hard winter freezes. Appropriate to grow in U.S. Department of Agriculture Hardiness Zones 7 through 10, the winter cold in zones 7 and 8 often causes this tree to become a much smaller multi-stemmed shrub. The large green, maple-like leaves make an attractive foil to the white-to-pink to deep-lavender changing flowers that don the branch tips in late summer through autumn.
Step 1 Prune off any broken or dead branches on the confederate rose bush any time you encounter them. Make the pruning cut 1/4 to 1/2 inch above a lower branch junction, leaf or dormant bud if no leaves are present. Step 2 Reduce the length of any branch or trunk in early spring to a height of 12 to 36 inches. Since larger diameter branches occur lower in the confederate rose, use loppers if they're wider than 3/4 inch in diameter. Time this reduction or rejuvenation pruning for just before the buds begin to swell and the leaves unfurl. In subtropical areas, this may mean pruning in late winter. Step 3 Clip off any suckering, thin shoots from the main trunk or larger, healthy stems on the confederate rose any time of year, too. Make the cuts flush with their attachment to the main trunk or even with the soil line. Step 4 Trim off old flowers once they fade if you do not want the seed capsules to form on the branches. Some find them attractively curious, as the seed capsules are fuzzy and split open to reveal a cottony core with seeds.

Tree roses, also called standard roses, are bush roses that have been budded onto a tall stem or trunk. Tree roses grow up to 4 feet tall.
Types Tree roses can be grafted from almost any rose variety. The most common types are hybrid tea, grandiflora and floribunda. Hybrid tea roses bloom on single stems and come in a vast array of colors. Floribunda roses are short, hardy bush roses that bloom in clusters. Grandiflora roses are like hybrid tea roses in their plant height and popularity as cut flowers, but have several blooms per stem and bloom more frequently than hybrid tea varieties. Features Prune tree roses according to the type of rose that is grafted onto the stem. Varieties that bloom only once per season should be pruned after flowering. Varieties that bloom repeatedly should be pruned during their dormant season.
Geography Roses grow best in full sun and well-drained acidic soil with a pH between 5.5 and 7.0. Amend soil with organic matter prior to planting to encourage drainage and help prevent iron deficiency. Mulch after planting to a depth of 2 to 4 inches.

Lavender roses are quite often described as enchanting and irresistible. Traditionally, the color of this rose has been appointed to mean love at first sight, and is given between lovers as a sign of such enchanting love. Lavender roses are a nice addition to any garden, adding colorful variety and wonderful contrast especially when paired with white roses.
Blue Moon A popular commercial variety of lavender roses is the "Blue Moon." This rose is a hybrid tea rose that will grow approximately 4.5 feet tall. "Blue Moon" lavender roses are known for their strong, sweet fragrance and large double-blooming petals. This type can be grown as a rose bush or as a climbing rose plant. Angel Face "Angel Face" is a lavender colored floribunda rose that will grow just about 4 feet tall. It has a sweet fruity fragrance and is typically a mauve lavender color. What is unique about "Angel Face" is that it will have a more blue lavender color in warmer climates. Resistant to most diseases, the "Angel Face" rose is easy to grow in home gardens. Barbra Streisand "Barbra Streisand" is another hybrid tea rose with a strikingly deep lavender color and a strong, citrus aroma. It has very large flowers and will bloom repeatedly throughout the late spring and early summer months.
Lagerfeld Named after the famous fashion designer, the "Lagerfeld" is a beautiful pale lavender and light gray color. This grandiflora rose has an understated old-rose fragrance Sterling Silver The "Sterling Silver" hybrid tea rose is said to be the first lavender rose that gained popularity for its distinctly silver and purple color. While the color may not be as vibrant as other lavender roses, this classic beauty has a traditional rose smell.

Climbing roses provide a colorful accent that can be trained onto trellises, around windows and doors or along eaves. The old-fashioned blooms have new life with today's modern hardscapes and landscape structures. Roses need at least six hours of sunlight a day, and the Texas climate provides that in spades. Climbers can flower just in spring, or flower repeatedly, giving a color show well into fall.
Old Garden Roses Roses in older gardens are often cultivars that don't exist anymore. They can be found creeping over walls and fences or even in cemeteries with no one to care for them. These climbers are being preserved through cuttings and reintroduced into cultivation. Schulenburg Apricot, Katy Road Pink and Highway 290 Pink Buttons are examples of some of the old garden roses. Old roses, which are any variety produced before 1867, are resistant to many common rose problems and can be trained as an espalier or trellis form. Lady Banks grows 20-foot-tall canes, and Cecile Brunner is not far behind with 15- to 20-foot canes. Either would be excellent choices for their old-fashioned pastel blooms and hardy climbing nature. 1950s Cultivars A lot of new cultivars were introduced in the 1950s. One of these, Climbing Pinkie, is an 8-foot-tall bush with semi-double pink flowers. The canes are thornless and the blooms carry a light fragrance. Don Juan Is a citrus-scented red rose that blooms fully even in the worst Texas heat. For vigor you can't beat Dortmund, a 1955 introduction. It can grow up to 30 feet tall and bears deep red flowers with a white center and bright yellow stamen. The roses have overlapping petals that give the blooms a frilled appearance. The thorns on this bush deserve respect as they are large and sharp.
Earth Kind Earth Kind is a designation from Texas A&M University that rates roses for their health, environmental friendliness and tolerance to Texas' extreme climate. Sea Foam is a moderate climber that only gets 3 feet tall and then cascades downward. None of the roses in the Earth Kind program have been treated with any chemicals or even fertilized. New Dawn was the first rose to be patented in the U.S. it is a fast climber that can grow to 20 feet tall, sporting white flowers with pink centers. Reve 'd Or is another vigorous species climber. The Earth Kind rose designation is now being used in other states to categorize rose bushes for responsible growers.

A Lady Banks rose (Rosa banksia) produces cascades of yellow or white flower clusters. It grows in U.S. Department of Agriculture plant hardiness zones 7 through 10. This wild rose looks best when allowed to grow in its natural form, but infrequent pruning can help keep it in bounds while still ensuring ample flowering.
Ready Your Shears Two types of shears are needed to prune a Lady Banks rose. Basic loppers handle most pruning needs, but you will need smaller hand pruners or bypass shears for shaping the bush. Wipe the shear blades with a cloth soaked in rubbing alcohol to disinfect them before you prune. If you cut out diseased wood or are moving between plants, wipe the shears again. Some varieties of Lady Banks roses have thorny stems, so wear leather gardening gloves and long sleeves if you are trimming a thorned variety. Timing Is Everything Lady Banks roses flower on 2- or 3-year-old canes, so they don't require annual pruning except to remove damaged wood. Pruning too frequently will remove the flowering canes so there are no blooms and only foliage. These roses only flower once a year in late spring or early summer. Prune Lady Banks immediately after this annual flowering, before the plant begins to set new buds for the following year. Thinning It Out Thinning allows for air circulation within the rose bush, which improves flowering and minimizes disease concerns. Yellow and brown canes are completely dead, so remove these at ground level using the loppers. You can also remove the tallest and thickest canes at ground level to open up the center of the plant for air circulation. Pruning these out also lets in more light, so the smaller canes can leaf out and set flower buds. Also, remove any damaged canes, either cutting them off at ground level or cutting them back to the nearest outward facing bud or leaf on healthy wood.
Shaping Up Light shaping every two years helps keep the sprawling, climbing canes of the Lady Banks rose under control, but you don't want to over prune and lose the plant's natural form. Begin by cutting back any overgrown canes, especially those that extend over walkways, or are wrapping around structures or tree branches. Cut these back to a bud or leaf at the desired cane length using the bypass shears. You can also prune back dull green canes to manage their height, but don't prune back the bright green canes because these are your future flowering stems. After pruning, remove the clippings from the bed, and compost or dispose of them.

Cloning roses is the process used to grow a new rose from the cutting of an old one. Typically a cutting or piece is taken from a fading rose bush or from a bouquet containing a variety that appeals to you, and you'd grow the same variety from that cutting. Cloning a rose is a long process that requires patience and attention to the cutting. Often clones begin to show progress in as little as a week, but some rose varieties can take much longer. Step 1 Remove your cutting from the plant below the point where the stem and main cane join (heel). An ideal cutting is 5 inches long with five groups of leaves (leaflets) and a spent (past bloom) flower. Step 2 Wrap the cutting with moist paper towel and place it in a sealed bag. Step 3 Add 1/8 teaspoon of Miracle-Gro and of baking soda (prevents fungus) and a few drops of dish soap into a 16-ounce spray bottle full of water and shake. Step 4 Fold the top of a zipper bag down about 2 inches and pour three cups of potting mix in. Step 5 Pour slightly less than a cup of water into the bagged soil and knead into the soil. Step 6 Press the bagged soil down and poke a hole into the center of the soil with your finger. Step 7 Remove the cutting from the paper towel and cut the stem about ½ inch above the leaflets at the top of the cutting. Step 8 Remove bottom leaves, leaving one large or two regular sized groups of leaves on the top of the stem. Step 9 Cut across the heel of the stem, or below the lowest point where the leaf stem joins the cane (eye bud). Step 10 Dip the cutting into liquid rooting compound and place it slanted into the hole you made, pressing the soil firmly around it. Step 11 Unfold the bag and spray inside with the spray bottle solution. Step 12 Close the zipper from both sides, leaving an inch open. Blow into the bag so that it expands before closing it completely. Step 13 Place the bag in an area with bright, indirect sunlight and watch for new growth.
Step 14 Remove dead leaves, bud, and fungus if necessary. If the soil cracks around the stem move it gently into the crack to firm it up. Step 15 Spray inside the bag and re-inflate it each time you open it. Step 16 Begin opening the bag (one inch for three hours the first day) when you see two or three new leaflets, growth at the top of the soil but no roots, or if you see new roots inside the bottom of the bag for several weeks. If it droops or the leaflets turn brown, blow up the bag and close it. Try again in a few days. Step 17 Close the bag after three hours if the cutting is unaffected. On the following day double the size of the opening and the length of time you open it (2 inches for 6 hours). Step 18 Continue opening the bag a little more each day for a longer period of time until the bag is fully open. Step 19 Fold down the top of the bag once the bag has remained open for a full day with no ill effects to the rose, and leave it open for four days. Step 20 Spray once each day after opening. You'll begin to see roots forming at the bottom of the bag indicating the rose is ready to pot after about 10 to 30 days.

No matter what the color, roses are beautiful flowers, but purple roses are particularly special. They are a symbol of enchantment to send to someone you admire. Roses of a purple hue are widely available, although less often seen planted in a garden or featured in a bouquet. Yet their unusual color is what makes them visually striking and desired by home gardeners wanting a distinctive colored rose to make their flower beds stand out.
Melody Perfume The melody perfume rose looks like a quintessential red rose in shape, but differs in color. Its blooms begin as a medium-dark lavender and transition to a pretty lilac as they age. It's named for its aromatic qualities that can fill an entire room with its intoxicating scent. The rose bush is medium size, about 5 feet tall at maturity, and stands upright. It has shiny, dark green foliage. Plant this rose in zones 5 through 9. Blue Moon Blue moon is a hybrid tea rose. Its purple-blue shade is what makes this rose unique. Blue moon produces large, ornamental blooms. One rose generally grows at the end of a long stem, which makes it suitable for displaying in a vase. It's a fragrant rose variety, which has a scent similar to a sweet tea. Plant this rose in warm weather climates, such as zones 5 through 9. It requires full sunshine to grow lots of flowers. When cultivated in the right growing conditions, it produces flowers all summer and fall.
Burgundy Iceberg Despite its name, the burgundy iceberg rose produces vibrant purple roses. This almost thornless rose variety has a mild sweet scent. Unlike other purple varieties, burgundy iceberg roses are hardy and tolerate cooler climates. Plant them in zones 4 through 9. Expect the rose bush to grow to 3 to 4 feet tall when fully grown. Burgundy iceberg is disease-resistant. Veilchenblau The unusually named Veilchenblau climbing roses have deep purple, flat petals with bright yellow centers. Streaks of white radiate from their center. Over time, their color lightens to a bluish gray. Flowers bloom in bunches. These hybrids produce one annual bloom. Cultivate it in zones 5 through 9 and train them to grow up a trellis or fence. They are drought-resistant and can handle moderately shaded areas.

Scientifically known as the Rosa rugosa, the beach rose is a sturdy, easy-to-grow shrub that enjoyed by landscapers and home gardeners alike. Not only are beach roses cold-tolerant and disease resistant, they will also withstand conditions that would send most rose bushes into a full wilt. They thrive in poor soil, salt air, windy environments and full sun. However, while they don't require the attention other rose bushes demand, they do need periodic trimming to look their best. Pruning beach roses eliminates old, unattractive or damaged wood, while promoting the growth of new foliage and flowers.
Step 1 Examine the rose bushes prior to the spring growth spurt. Not only will the beach rose recover more quickly from pruning during the dormant period, it will make spotting unwanted canes easier as there is bound to be little, if any, foliage on the branches. Step 2 Remove any branches that have been killed by frost. These will be a dull brown color and will have no buds or new growth on them. Hold the pruning shears at a 45-degree angle and cut the branch, removing as much of the dead plant tissue as possible. Cut the branch back to the base of the shrub, if necessary. If you're not sure where the dead wood ends and the healthy growth begins, simply look at the center of a cut branch. Living canes are white in the center, while dead canes are brown. Step 3 Trim any damaged canes, cutting them back to the place where they connect with larger branches. Additionally, remove any branches that are growing inward, toward the heart of the plant, rather than out toward the open air. This thins the shrub and allows air to circulate more freely around the branches, which helps to discourage the development of diseases. Step 4 Eliminate crossed branches by cutting away the smaller of the two. If left unattended, the canes will rub against each other as they grow, damaging the protective bark and leaving the shrub vulnerable to invasion by pests.
Step 5 Examine the base of the shrub. Locate the bud where the branches emerge from the roots and trim away any growth found below this nodule. These offshoots are known as suckers and their development drains the energy resources of the plant. Step 6 Sculpt and shape the shrub, if desired. Cut the canes back, removing up to one-third of each branch to control height. Alternatively, you can remove whole canes, cutting them completely back to the base of the shrub, to control the width. Take care not to remove more than 30 percent of the total plant material.

The ability of a plant to obtain necessary plant nutrients depends largely on the pH of its soil, measured on a scale of 1 to 14. Acidic soil, sometimes called "sour" soil, has a pH below 7, considered neutral. Alkaline soil, sometimes called "sweet" soil, has a pH above 7. Most rose cultivars prefer a pH between 6 and 7. If your soil pH is below 6, you can increase the number by adding lime.
Climate and Soil There are between 150 and 300 species and 6,000 cultivars in the Rosa genus. Roses will grow in most soils that have a high organic content, in U.S. Department of Agriculture plant hardiness zones 4b to 10b, depending on the species and cultivar. To determine if you need to add lime to your soil you have to know its pH. Test it either in the fall or spring. Testing Soil pH Use a spade, spoon or trowel to take a sample from the top 6 to 8 inches of soil. Do not do this when the soil is wet. Spread the sample on plastic wrap and let it dry overnight. When it's completely dry, remove stones and solid matter and put the soil in a plastic bag. It's now ready to test using a home soil testing kit that you can buy from most garden supply centers. Alternatively, you can have it tested by a commercial testing service that will also tell you of any mineral deficiencies in the soil. If your soil pH is too low for roses, add lime to raise the number. How Much Lime to Apply Finely ground limestone, calcium carbonate, available at most garden supply centers, is typically recommended for home gardeners. How much lime to apply to raise soil pH to 6.5, ideal for roses, depends on the type of soil. For clay soil: Add 29 1/2 ounces of lime per square yard to raise pH from 5.5 to 6.5, 41 1/4 ounces per square yard to 5 pH clay soil, and 53 ounces per square yard for 4.5 pH, per recommendations from The Royal Horticultural Society. For loam soil: Add 23 1/2 ounces of lime per square yard to raise pH from 5.5 to 6.5, 35 1/4 ounces per square yard on 5 pH loam soil, and 44 1/4 ounces per square yard on 4.5 pH. For sandy soil: Add 20 1/2 ounces of lime per square yard to raise pH from 5.5 to 6.5, 29 1/2 ounces per square yard to 5 pH sandy soil, and 38 1/4 ounces to 4.5 pH.
How to Apply Winter is a good time to apply lime. If you apply more than 14 3/4 ounces of lime per square yard, dig half of it into the top 6 inches of soil and sprinkle the other half on the surface when you're finished. If you apply less than that amount per square yard, dig all of it into the soil. If digging is impractical, sprinkle all of it on top of the soil. It's best to add lime before you plant roses. If you sprinkle it around plants, it can take years to have any effect.

Sometimes roses are so beautiful that you may wish they would last forever. Luckily, with a bit of time and knowhow, your roses can be preserved. Although air drying is a simple, tried and true method, many experts believe that drying roses in silica gel is the best method of desiccation for roses and other flowers that have thick petals. Silica gel is a drying agent that will extract the moisture from the blooms while leaving their shapes and colors intact.
Step 1 Gather roses that are similar in size. If you are picking the roses from your own garden, harvest them in mid-morning on a dry day. Use only healthy, disease-free roses that are nearly at their peak. Step 2 Remove the leaves from the stem and cut the stem down to 2 or 3 inches. Step 3 Spread an inch of silica gel in the bottom of an airtight plastic container. Step 4 Arrange the roses on top of the silica gel. Step 5 Add silica gel around and on top of the roses until the blooms are completely covered with the gel. Add the gel a little at a time, jiggling the container after each addition to settle the gel around the roses before adding more. Step 6 Check the roses after three to five days. Remove the lid and use a soft paintbrush to remove enough silica gel to enable you to access the rose. Touch a rose petal gently. The petal should feel papery and dry. If the rose isn't quite dry, replace the gel and check again the following day. Step 7 Remove the roses from the silica gel when the blooms are completely dry, and use the soft paintbrush to gently brush excess silica gel from the blooms. Don't over-dry the roses, as the petals will become brittle and break easily. Step 8 Create a stem with 20-gauge florist's wire. Push the end of the wire horizontally through the base of the rose, with about 2 inches of wire extending from the side of the stem base. Bend the short end of the wire down and wrap it around the longer wire and the rose stem. Cut the long end of the wire to the desired length, then wrap the wire with florist's tape.
Step 9 Gather a small bunch of about three to five roses with their foliage removed. Secure the bottom of the stems together with a rubber band. Step 10 Hang the roses upside down from a hook in a dark, dry, well-ventilated room. Leave the roses for two to three weeks. Step 11 Remove the dry roses form the hook. Spray the roses lightly with aerosol hair spray to strengthen their petals.
