|'Amadis' is a Boursault rose which produces large, cupped, semi-double deep crimson and purple flowers that are borne in clusters. This plant is a thornless climber with long, arching shoots which mature from green to a brownish-purple. It blooms early in the season. Partial shade brings out the subtle colors.
In general, roses are a large group of flowering shrubs, most with showy flowers that are single-petalled to fully double petalled. Leaves are typically medium to dark green, glossy, and ovate, with finely toothed edges. Vary in size from 1/2 inch to 6 inches, five petals to more than 30, and in nearly every color. Often the flowers are very fragrant.
Most varieties grow on long canes that sometimes climb. Unfortunately, this favorite plant is quite susceptible to a variety of diseases and pests, many of which can be controlled with good cultural practices.
