It prefers at least 4-6 hours worth of sun each day & it is not a drought tolerant peony, getting smaller each year if grown in drier, unirrigated locations.

Thanks for the information. It has been in the same location for approx. 7 yrs. and has always done very well(large and full with many blooms) yet this year, just a small plant with foliage only. Perhaps it is due to the crazy spring we had with the thawing and freezing cycle carrying into late spring. A number of my hostas are undersized this year as well and I did lose plants this year. Thanks again for your interest.

Is it getting enough sunlight? I have had to do some branch trimming this year. I notice when the plants don't get as big, something has changed in the setting.

My fernleaf also likes being watered in his location near the big oak tree. I think the tree takes a lot of the moisture, so make sure the fernleaf has plenty. Mine stays green pretty late into summer with the extra water. I love the lacy leaves, so try to stretch out their green time. With the branch trimming, more sun, my fernleaf put on a great show this year.
