Types of Roses|
Bush roses are generally upright-growing plants that bear flowers mainly on top of the plant. Needing no support, these roses may grow from 5 or 6 inches to 5 or 6 feet tall, depending on the type and climate. The types of bush roses include hybrid teas, polyanthas, floribundas, grandifloras, miniatures, and heritage, or old roses.
Climbers have long, arching canes that don't actually climb but must be attached to supports such as trellises, arbors, posts, or fences. There are many different colors and types of blooms available. The large-flowered climbers have stiff, thick canes 10 feet or so long and bloom either continuously or at least several times during summer and fall. Ramblers have longer, thinner canes with clusters of small flowers borne once in late spring or early summer.
Shrub roses grow broadly upright with gracefully arching canes. Most are very hardy and require little maintenance. Depending on the variety, they may be 4 to 12 feet tall with many canes and thick foliage, making them ideal for hedges as well as background and mass plantings. The flowers may be single (five petals), semi-double, or double and are borne at the ends of canes and on branches along the canes. Some types bloom just once in the spring while others flower continuously during the growing season. Shrub roses frequently produce red, orange, or yellow hips (seed pods) after flowering. These are high in Vitamin C and can be used in cooking; plus, the birds like them for winter food, and they can be used in flower arrangements. (For more information on arrangements, see the American Rose Society: Arrangements.
Ground cover roses are prostrate or slightly mounding plants with canes trailing along the ground. Flowers may be produced just in the spring or repeatedly throughout the summer at the ends of canes as well as on branches along the canes.
A tree rose is any one that has been bud-grafted on a straight, sturdy trunk. These trunks may be 1 to 2 feet tall for types like miniatures and floribundas or 3 to 4 feet tall for hybrid teas. Climbers budded on 6-foot trunks create a weeping effect. Any of these require careful pruning and special winter protection in all but the mildest areas.
