Nutcutlet - perhaps it depends on where the original poster lives. If, like me, it is in rural spot, there are lots (and lots) of these plants growing in the wild. It would probably explain how it came to germinate in a domestic garden. So the Orange Tip is likely to have more than a sufficiency of plants for habitat (they do here in Devon, and are very pretty butterflies - much better than cabbage whites, at least).
