Favourite Perenials?

I would certainly agree with Tigerlilly about the two Geraniums. I understand that they are both sterile hybrids - which in part explains why they flower for such a long time. [The purpose of flowers is to attract insects to fertilise them, and then produce seed - once fertilised the flowers fall off as they are no longer needed. But sterile plants never get fertilised].

My own approach is to find long flowering plants and I listed some in another thread. http://www.gardenerscorner.co.uk/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=1;t=003578

 

Ive got a whopping long shopping list Thank you for all the suggestions, I just wish I could get out in the garden and start!
