Would it be okay to purchase Penstomen ‘heavenly blue’ and Penstomen ‘alice hindley’ in 9cm pots now and plant them straight into the open ground or would it be cosidered to late in the year.



Well I wouldn't risk it, especially where you are, unless you're right on the coast. I used to live in Kent and it gets surprisingly cold in winter at times, and when they're very small, Penstemon aren't the hardiest of plants. You could buy now and pot them up, keep them in a greenhouse over winter, or somewhere frost free but not too warm. If we knew we were going to have a long indian summer, right up to the end of October, then that'd be different - but we never do know, do we!

I agree with Bamboo, I purchased some Penstemen plants from a well-known mail order supplier but lost some of them over the first winter. Some of the varieties are hardy but some not so much.
