buddleia colvilei

Hi all, I've acquired some cutting material from Buddleia colvilei. How would I best treat it? The wood is fairly mature but probably not quite hardwood.

     I love the word "acquired"

    Is that the one with slightly furry leaves? I've never grown in but most buddleias I have acquired,  I shove it in a gritty compost with a dab of rooting powder. If its got furry leaves I would not cover with a plastic bag, as I think condensation would cause rot.

    A buddlei globosa I acquired while out walking  next doors dog,is doing ok, nearly ready for a final home.

    This one was acquired in the presence of it's owner fb. He says it's not as hardy as some, he's got it in a sheltered place. I'll set as you suggest with a view to bringing it indoors if it gets very cold perhaps?. My GH is cold. Keeping the cuttings in a glass of water on the kitchen windowsill til tomorrow, it was dark when I got them home

    I'd like to have a few different buddleia species. I've grown B. loricata from seed this year. Don't think that's too hardy either.

    Burncoose list it as on the tender side, so I have never tried it this far north, even though I have had a lot of different buddlejas over the years.

    I seem to be ok with davidii cultivars- pink, white, nanho blue, dartmoor, harlequin (weak), and globosa and x weyerana, and alternifolia.

     I found B. fallowiana pretty, but weak and I lost it.

     The butterflies seem to prefer the wild pale purple  davidii type, in preference to the other colours.

    I doubt if we're much warmer than you and it may be daft to be growing them but I like producing plants. I could fiddle around propagating for hours

    I have a lot of plants that started out as small cuttings. My grandmother started me off. She grew an entire hedge of lavender by just pushing in cuttings in a line, taken from a bush a neighbour had discarded. She did have very sandy soil, so that probably helped. I just thought it was amazing.

    Maybe  B. colvilei would grow in a pot, and then have the shelter of the cold greenhouse in winter. It does look a beautiful flower. Its supposed to be a bit hardier as it gets bigger, so maybe plant it out second year?

    Yes, that could work. I like to have a few pots around, with something a bit different in them. I'm hoping these will take, my record with cuttings isn't great

    Maybe a bit of bottom heat?. Have you got a plug in propagator, with the large dome top?

    I have, hadn't thought of that. Haven't  used it for years but expect it still works. Thanks for reminding me. Maybe I'll put the Bupleurum fruitcosum cuttings in there as well
