I've had Russian Easter since 2007 and I agree that it adds a nice, soft color to the garden. It is not one that everyone would say "what is that way over there", but it does blend well with other daylilies. Branching is probably two-way as seen in one of the pictures below and probably only about 8-10 blooms per scape.
I have not divided or moved Russian Easter since I purchased it, so I do not believe that it is a fast increaser. I don't recall seeing rust on it. A club member told me once that we don't see rust here in our area until around August, so I will have to check then.
In summary, I think the reason I keep it is because of the soft color, sturdy scapes, and it's nice height. Not saying I won't ever get rid of it, but it is always a pleasure to see it in bloom.
