I am toying with the idea of introducing a cultivated Rosebay willow herb into my borders as I would really like to encourage elephant hawk moth caterpillas into our garden.
I am aware that the cultivated plant is sterile and spreads by rhizomes quite vigorously , but I'm wondering how vigorously? Will it take over my garden? I'm currently fighting a losing battle with hedge woundwort which I stupidly let grow for the bees ( and is now taking over...it stinks by the way!), and I don't want to make the same mistake Again.
does anyone else grow this in their gardens?
