I have grown Jellyfish Jealousy for many years. It has been noted elsewhere to be a slow increaser. I think that it is slow to get established, but once gets established, it increases at a moderate rate. This year it was spectacular. I had nine scapes and all were at different heights throughout the clump, so the spacing of the blooms was spectacular. Most scapes had three way branching with about 15 buds per scape. It bloomed over a long period of time. If I correctly recall, it was the first spidery plant I added to my collection. This is one that will remain in my collection. I can say that the pollen is fertile. I did not try to set any pods on it this year. Visitors frequently comment on it as the blooms appear to be floating on air.
