    Default Anyone grow tropaeolum speciosum (flame flower)?

    I've seen this in gardens I've visited and love it. Thought it would be great to prettify my fugly leylandii hedge.

    Chiltern Seeds sell it but it's always out of stock. A month or two back I had an email saying it was back in stock, but by the time I looked (approx 1 hour after the email) it had already sold out again. Now it's back in stock again.

    Germination instructions are so fiddly - file it, sow, warm place, freezing place, cool place, wait for months. I must admit I had thought it was perennial but apparently it's only annual, according to Chilterns. Is it worth it? Does it self-seed?

    RHS site implies it's perennial as it says "Time to ultimate height: 5-10 years"

    I'm on acid clay but on a slope so it drains.

    Sod it, I'm ordering.

    Definitely perennial once it gets going, I bought a plant as it seemed fussy from seeds. It needs an acid soil to do well, so ideal under a conifer hedge, where the pine needles keep the soil acidic.
    Good luck!

    Difficult to propagate and difficult to get rid of once it's established but such a cutie

    I can’t imagine wanting to get rid of it. Sounds like my difficulties won’t be over even if I succeed with germination.

    I've just looked it up- I don't think I'd worry about being over run!

    Scarlet one of the times I was visiting the RHS Gardens in Edinburgh they were stripping tropaeolum from their hedges and it took at least three trailer loads while I was there, it is difficult to establish and like all nasturtiums it does well in poor soil, I have also heard, it grows better from cuttings if it is borrowed without permition

    it may be a struggle to reach the top, but once your over the hill your problems start.

    I've seen it growing like a weed at Edinburgh Botanics and it looks lovely. I therefore know it is possible in my neck of the woods.

    However I've tried twice from potted plants. First time a snail ate the whole plant before I could even get it planted out. Second time it grew for a season, looked fine, but never came back the following year. Neither plant was cheap to buy so I haven't tried since. I've since moved and may give it a go in my new garden. Growing from seed - sounds like a good option.
