Jubilee (syn 'Dr. Rushpler').  This magnificent variety produces very vigorous large dark green foliage and long flower stems.  The flowers are very large, reaching 6 ins. across under good culture, outer petals partially reflexed and recurved, the centre petals upright and very gracefully disposed;  the buds are long and rounded, the petals falling away gracefully, revealing the rich velvety texture; the fragrance is strong, delightfully rich, and lasting. The colouring is alive, a pure red in its deepest tone, shading to a deep crimson red and velvety maroon red in depth of its petals.
