I agree. I quite like it in the garden, it does seed about but has attractive flowers and foliage.

Break a stem and get a surprise Alistair - the sap is an unusual colour! and it used to be used very effectively for getting rid of warts.

I had a gift of one of these in a pot this spring. it is pretty.
