You will have to rescue some Ginger, you might find some interesting colours! Lupins are an old plant much neglected now but they really do have a lot to offer. I love to see any new colours I get, I have a few set around the yellow one but they make lots of seed which is flung around when they 'pop'. The pod halves also twist around each other on the yellow one, I don't think I've seen the twisting on others. I had a look at the pods today but all the seed has been flung and I'm wondering what the seedlings are going to do, I might have to move some. It's surprising there isn't plants everywhere but I think many get eaten, this year I have taken some from most plants I have and spread some around. If I get flowers and seed from the Tree Lupin I wil have to keep some seed as insurance.
