Hi

If anyone could help with the identification of this plant I would
appreciate it very much.

This is a hardy plant which will self seed around the garden. Strangely it
never seems to grow near itself. It carries purple flowers on the top of
the main stem and on top of each branch.
The plant branches symetrically, so you always get two branches (one either
side of the stem) each time.
I can grow between 2 and 6 feet tall. The plant does not seem to have that
many leaves for its size.
The bees and butterflies like it.

Here is a pic of the flowers I took earlier this year.

If there are any other questions i can answer to help with the ID please
post them and I will ge back to you.

Many thanks

Phil
