i planted delphinium volkerfrieden in February this year indoors and they have been out all summer. They are now around 20-30cm tall. What should I do with them over the winter? Bring them back indoors?
Delphinium 'Volkerfrieden' is a fully hardy perennial , and should overwinter with no problems . If still in pots though , it wouldn't hurt to move into a cold greenhouse or coldframe for their first winter ; more as a protection against excessive wet .
