I’ve grown some perennial plants from seed (Gaura, Dierama, Potentilla, Penstemon barbatus, Verbena rigida and aquilegia) and I was wondering whether they can overwinter in a plastic greenhouse. I am planning to pot them separately and plant them out next spring. Is that a good idea? Thank you.
They are a bit small, March would have been best to sow the seeds, but some will overwinter as they are hardy.
The guara may not survive outside, some places it doesn’t survive the winter as big plants.
