I'm going to be unhelpful and tell you I have Hanakisoi that is too young to bloom. However, I saw one of blooming size that was 5 1/2 feet tall in a tiny pot. Has the one in the nursery bloomed already? Some nurseries drop their prices after the peonies have bloomed. (It sounds expensive, but I don't know if that is the usual price where you live.)

No bloom yet. 3 buds ready to go. I'll wait and see if they drop the price. I know that last year they have Bartzillar left by September and I paid $5 for it. Hopefully, they'll have some hanakisoi left by then.

Bartzella for 5$ is amazing. I had gotten one tree for $15 and an herbaceous for $5 last year and I had been pretty darn happy about that :) Over here, Hanakisoi is common in nurseries (the same 5 cultivars are sold all over). There are nurseries that sell it for $55, but there are others that sell it for $30, so I am biased against paying $60 for it.

Some manager/owners are willing to discount a plant after it blooms or at the end of the growing season if you talk to them. Sometimes, they're just eager to get rid of surplus. Though, that has only happened to me at the small nurseries.
