    B. davidii flowers once- technically, but you get repeat flowering over a period of time if you deadhead regularly, or if you only prune back part of a shrub to delay flowering. 

    I don't know if the earlier flowering B.globosa produces a 2nd flush - maybe in some areas, depending on climate. 
    It's a place where beautiful isn't enough of a word....

    My davidii buddleias flower all summer once they get going but I do dead head them regularly to keep them going.   I have a new globosa which flowered earlier and I have dead headed that too but so far all it has produced is healthy new growth.  Fine by me as that means more flowers next year.

  • Our globosa will continue flowering but only as @Fairygirl says if we deadhead them.

    Oh good.  Looking forward to mine doing that next year then, when it's a bit bigger.

  • Ours is cut right back in the winter so that just the main trunk is left.
    Every year it then sends up new shoots and flowers brilliantly.
    The bees and butterflies love it much more than our davidii. The moths are also on the flowers in early evening and when we did have bats (gone due to developments near us) we could then watch them hunting the moths.
    A great plant.

    On globosa? It's supposed to only flower on old wood. It's why I've let mine grow large because the wildlife absolutely love the flowers.

    So that disproves the theory that the Globosa flowers on last year’s wood!

  • Well all I can say is that the plant we bought decades ago was labelled as globosa, so we have always said that this is what it is.
    Maybe the labelling was wrong but the flowers match up to globosa.

    I bought a globosa a few years ago which turned out to be a weyeriana. If you’re pruning hard early in the year and still getting plenty of flowers, I suspect you’ve also got a weyeriana. I now have a globosa from cuttings I took from plant on a grass verge. This definitely flowers on older wood.
