hi, i have a very tall plant, about 5 ft, it has a thick stem with many fonds of leaves that look like maiden head fern leaves and along these are clusters of very delicate purple flowes. i dont know the name of the plant even though i planted it myself last year as a very small plant. the main problem is what to do with it now it has finished flowering and what is its name help please
Did you take a photo pam? Could be a thalictrum but the description could be something else
In the sticks near Peterborough
Sounds like Thalictrum to me.
Have a look at Thalictrum delavayi and see if that matches if you can't load a photo.
well done! i googled thalictrum and it is the delavayi, how did you know? do you have one and do you know what to do with it now its finished flowering? thanks
The RHS says cut down when flowering is over.
I let it form seed because it doesn't last long as a plant. In later years the seedlings take over.
Ive got one Pam and I let it go to seed then give it a good shake and cut it down sometime during autumn usually.
thanks everyone, i'll see how it gets on nexy year
