How to grow persian buttercup

When to plant persian buttercup

Plant Persian buttercup tubers, claws pointing down, several weeks before the last frost date, or start them indoors and plant out in spring before hot summer weather (NC State). They are a cool-season grower that goes dormant in summer; dig the tubers and store them dry and cool to save them for the next season.

Persian Buttercup is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
