English Rose (aka David Austin) - not an official class. The idea was to create a new group of roses that featured blooms with old-fashioned shapes and fragrances but with modern repeat-blooming characteristics and the larger modern colour range as well. This example is 'William Morris'
Hybrid Tea Rose - the most commonly used type of rose in floristry. They generally have blooms at the end of long stems, are upright, vase shaped and vary in leaf color. They repeat blooming about every six weeks. This example is 'Cesar E Chavez'
Floribunda Rose - These are a similar shape to the Hybrid Teas although they may grow a little taller. The difference is that the blooms grow in clusters and therefore tend to be a little smaller than the Teas. These are best if you want clusters or bunches of blooms on a stem. This example is 'Gene Boerner'
Polyantha Rose - Literally "many-flowered" roses, from the Greek "poly" (many) and "anthos" (flower). They feature small flowers, 1 inch, carried in large sprays in white, pink and red. This example is 'The Fairy'
