Appeal for help from anyone who knows these Penstemon. Bought 2 in pots in May when they were about 6" high and planted the same day.
I bought them because I was dazzled by the photograph of the flowering plant on the pot label and because I had read they had proved to be prolific flowerers, strong growers and hardy in all weather conditions. Mm!
Well, here they are now 2 months on and they still cannot support themselves. Each one had three stems when bought but whilst they have grown just over a foot tall, they can't stand on their own and the stems are still soft. Now one is producing buds but I'm sure the stems will not be able to support them.
I was thinking of pulling them up and replanting them somewhere else - but don't want to lose them if there's anything I can do to tough them up to become self-supporting.
HELP anyone? Should they be as floppy as this and have I not done something I should have to get them to firm up?
