Penstemons offer...10 for £10...how would I over-winter them?
Dorset, United Kingdom
If I bought these plants...10 different beautiful varieties...now, just as the cold weather starts...how would I look after them? I don't have the ground space for them & the frosts can be vicious, (tho' they are said to be hardy), even in the greenhouse so would I have to keep them indoors in a container & keep them waterered? Would they grow bigger during the winter or sit dormant?
Sorry...lots of questions!
