Heliopsis helianthoides - Does anyone grow?

Hello,

I'm looking for something tall and perennial to pad out a harvest colours border, (red, yellow, orange) and I think I have never tried the above.

If you grow them, do they have any weaknesses/preferences that you are aware of? Are they reliably perennial and hardy? Are snails likely to eat them?  I thought the leaves looked fairly robust in photos but can't be sure.

Border is improved clay but still heavy, dries out in summer but not boggy in winter.  Sun from south west/west.

    I don't have that variety, but I did sow some Heliopsis Summer Nights in 2017.
    They've done well and I love 'em.
    They're mixed in with some Stipa Gigantea and other plants that have arrived on the wind like toadflax, feverfew, foxgloves and the daisies.



    Slugs in early spring do love them though and I have lost a couple due to them being continually munched, but the 5-6 clumps I have of them are quite large now, so I can split them as necessary. They do self-seed a little, so I can sometimes fine a seedling to pot up and bring on.

    The dark stems and dark leaves (early in the season) look good too. The leaves eventually turn green .

    Sometimes I Chelsea chop them which helps keep the height down a bit, other times I don't and some will flop (they get to about 6ft), but they give a great display throughout summer until late October.

    Well that looks lovely @Pete.8, thank you for that.  I don't think my display would look so natural and wonderful but I think they would make a good filler for mid to rear border.  Perhaps I should grow them on in pots if I buy smaller specimens...It's quite a snail heavy area, slugs less so. Thanks for the flowering time info also, I could do with something that lasts later in the season.

    The words natural and neglected are often interchangeable :)

    It's just an area I can't decide what to do with, so I planted the Stipa, then the heliopsis then pretty much left it to get on with it.
    There was a massive eucalyptus there previously where nothing could grow.

    The ground there is stone-hard orangey clay that has never been improved, and the heliposis did suffer badly in the heatwave/drought (I didn't water them) and several appeared to be dead. But soon as the rain turned up they resprouted and flowered profusely.

    I just had 4000L manure delivered, so will be spreading some of that around the area sometime before spring as I think it deserves it.

    But I thoroughly recommend the heliopsis.
    I did previously plant helenium there, but the slugs/snails decimated them to death. The heliopsis must be tougher.

    They were easy from seed, but a good idea to keep small plants potted until they look robust enough.

  • That's good news if the heliopsis are tougher than helenium.  I have helenium in the border and they survive the snail but aren't exactly bountiful. I'm going to order a couple and see how they get on.  Many thanks :)

  • @Victoria Sponge There is one called H Fire Twister that is fairly new from the US I believe. Not sure it is available yet in the GC's.

    @GardenerSuze, thank you, that one is bright as a button!  A little shorter than I need for this space but one I would certainly consider for nearer the front.  A fab pop of colour  :)

    I had a voucher code from Bean Nursery which I have used once before so I ordered Bleeding Hearts and Burning Hearts and will see how they get on.

  • @Victoria Sponge A friend grows Bleeding Hearts and Burning Hearts and she is very pleased with both, She does have deep soil which I think they enjoy.

    I did buy Fire Twister for her as a gift, amazingly found just one pot half price it was fine just needed more water. She has hundreds of plants but didn't have that one so I was pleased .I do know people were talking about it at the flower shows in 2019 but I couldn't find it at the time. It has plant breeders rights on it so that might limit the stock.
