Roses are one of the most popular garden flowers in the world, according to Purdue University. These flowering perennials are desirable for their showy blooms and often for their strong, pleasing fragrance. Some roses have elaborately ruffled flowers, while others are much more simple. Some are ever-blooming, producing flowers all summer long, while others flower one time only. There are many different types of roses. Some are species roses and others have been hybridized.
These roses are true to their species. They are as nature intended. Most feature simple, five-petaled flowers. Species roses can be groundcovers, shrubs or climbing roses. They are known for their hardy nature and minimal care needs, according to the University of Illinois. Rosa rugosa is the most popular species rose sold today, although it has also been highly hybridized (cross-bred with other types of roses).
Miniature roses are just like their larger counterparts, only in miniature form. They are usually dwarf versions of the larger-flowering hybrids. These roses range in size from 6 to 18 inches tall. Miniature roses can be used to line borders or in rock gardens. They are often cultivated in pots and can be grown indoors. Most are ever-blooming and hardy.
Hybrid tea roses produce just one, large flower per stem and are most often cultivated for cutting. These flowers have a beautiful fragrance and are a favorite with florists, according to the All-American Rose Selections website. They are usually grown either as individual specimen plants or grouped together with other hybrid tea roses.
Floribundas are a hybridized rose similar to tea roses but with more flowers per stem. The flowers, which are smaller than tea roses, can range from three on one stem to as many as 15, according to the All-American Rose Selections website. Floribundas come in a wide range of colors, from vibrant to pastel, and grow as shrubs. They are known for their prolific blooming and make a stunning accent plant, whether alone or in a group.
Grandifloras combine the best features of the hybrid tea and floribunda roses. These rose bushes are tall and sophisticated, featuring ever-blooming flowers. The flowers are wide, elaborate, fragrant and usually feature one per stem, although the stems are shorter than the true tea roses. Grandiflora rose bushes can grow up to 6 feet tall, according to Purdue University.
