hi, i have had my garden for almost 4 years this plant pictured has been there all this time but this year has gone crazy , it must be due to the rotted manure i put on the roses next to it last year !!! but it wonderful for a short time then almost disappears , someone suggested it may be a skunk cabbage but i cant a similur one pictured ! the roses next to it are very old original to my victorian house i have been told ! The garden was in a state when i bought the house and have tried to keep the bones as much as possible, but this plant has me straching my head !!!
