I have some new plants that have just appeared in my garden from nowhere and would like to dive into your fountain of knowledge if you don't mind?
The yellow one comes on a very, very thin stem that has to be supported as it can't stand up otherwise. There is also a pink one beside it. Full sun in a border
The purple one has grown through a shrub, about 1.5m high. Half sun.
The white one has sprouted underneath a tree, half sun I would say.
