Extremely rare, and to my knowledge not available in the US elsewhere, is this selection from Dr. Hans Simon of Germany. Plump buds open to pendulous bell-shaped flowers, holding them in almost horizontal position. The leaves are mid-green and pleated. Not hard to grow but very slow in the propagation, yielding only very few a year. May be shipped as bare root early in spring and later as potted, yet not rooted-in plants.
