Clematis integrifolia

Hello all,

Does anyone grow forms of Clematis integrifolia? In general I have success with Clematis even in my heavy very alkaline soil. But although C. integrifolia will grow, they aren't flowering or bulking up. I do have a very serious slug/snail problem and am wondering whether they are suffering more from this than the climbing varieties.

    I grew a Hendryetta very successfully in deep, fertile alkaline soil in my last garden.  It sometimes would suddenly dry to a  crisp in midsummer but would then regrow and flower again.  I also had an Arabella in another bed which had more neutral clay and it was a very happy plant. but both benefited from slug traps to protect them in spring when the tender new growth started.

    However, I also planted the shorter integrifolia alba, rosa and a purple leaved version with white flowers but they all failed after one or two seasons.  I think maybe they found winters just a bit hard because other clematis did well in the same bed and aspect

    Lots in the garden here on alkaline soil, here is Alionushka and Blue Rain, all grow very well, but I find it best not to plant deep as per some clematis, and we never feed or water them.

    My new Lilac Wine, I have just Registered, grows underneath a huge Bramley apple tree and is very happy, bone dry.

  • Thank you for the lovely photos! It could be the winters. One I am certain went down to slugs. The other two I have, 'Rooguchi' and 'Alionuschka' have been regrowing each year (now three years since I planted the first and two since I planted the second) but remain at a single stem each and have never flowered. I am now trying to remember whether I planted them deeply or not. I do find them lovely so hope they will pick up some speed.

    Obviously if yours is thriving under a tree, Richard, then shade is not likely to be the issue...

    Your Lilac Wine is just luscious Richard.   Hope it's a success for you and the nursery.

  • I love Lilac Wine too. I have had my eye on a quirky one with twisted petals called 'Hanajima', which is pink.

    The pink form of integrifolia, rosea, is a good pink. Here in our border in Summer

    Rosea is a good pink which is why I chose it to grow with my Sceptr'd Isle, William Shakespeare and Gertride Jekyll roses but she only flowered well for 2 years and then failed to re-appear one spring.  To be fair William Shakespeare was a wuss too and yet it was the sunniest and most sheltered bed in the garden.   Princess Diana, Sunset and Betty Corning loved it and Hendryetta too when she wasn't having a crispy strop.

    I've bought a Jan Fopma to try here.
