You may find more  info under  the  name Isopyrum henryi.    These  ranuculaceae are  ephemerals and so there  may be  an anxious wait  for them ti reappear  in Spring!

Plant Delights nursery  has  some  advice  : https://www.plantdelights.com/collections/isopyrum

and  it  may be  a  good  idea to ask Bjørnar Olsen  ( "arisaema"  in the forum) of Chinese  alpines!

David Shaw had rather big plants last year, you could try contacting him!

In general, think of it as a Paraquilegia growing in a warm temperate climate. Water from above shouldn't be damaging, C China gets heavy thunderstorms and rains in summer, and it gets hot in day time, occasionally 30C or more. Winters are generally mild, weather statistics for Xiangxi for the last 8 years gives a low of -4C in January. Winters in China have become a lot warmer over the last 20 years, so I would not be surprised to see it hardy down towards -10C, just avoid prolonged freezes.

Lisa at Growild is going to do an experiment with GA3, she didn't have luck in the past, so I'd be very interested in any reports on successes. The seeds look very much like Aquilegia, so we don't think they're ephemeral - but again, we have no data to go on.
