I have several Adenophora sp. seeds that you can have. They are beautiful, but I must warn you they can become VERY invasive. You do not only have to deadhead them in time, but also keep them confined in a container in order to keep control of the 'running roots'.
What do you mean by 'Trailing antirhhinum'? Asarina scandens? If so, I can supply you with seeds of the violet-blue one with a white throat and the mauve-pink variety (gorgeous!).
In exchange I would like to have a large mail telling me about your life during the time you were not active at DG and pictures of your lovely grandson.
babalu, as I have just harvested some seeds from my Abutilon vitifolium I am happy to send you some.
I have one seed pod from the blue one, with 44 good seeds in, one more pod nearly ready.
I also have a white one which was supposed to be blue, which is also very pretty and I have 6 good pods from that so far, haven't counted the seeds though!
I grew mine from seed and they are very easy to grow. I don't really need any of the seeds you are offering, I tried Erica coccinea from finebushpeople in SA but they didn't grow, if I could get that I would be very pleased!
