Could anyone tell me where I could purchase a double red fernleaf peony. I'm in the Fort Myers Florida area.Thank you in advance.
I don't think you will ever see P. tenuifolia bloom in Florida. This peony even more than others requires extended cold and winter freeze for the buds to break in spring.
Otherwise these are offered by The Peony Garden of Center Point Iowa. There are other peony nurseries that offer this also.
