I have a few weyerianas; moonlight, goldenglow and honeycombe I think they are. They are still small but I have found that they start flowering later than the davidiis but then carry on for a very long time. They are still flowering now and last year I remember the moonlight flowers having snow on.
They do seem to mainly attract bees but the occasional butterfly too. Commas seem particularly keen. I hope to learn more as the plants grow.
