Rudbeckias gone mad

AlxNicAlxNic Posts: 259

Last year I planted a couple of rudbeckias - the yellow ones with black centre and I was pleased that they grew and flowered. This year there's so many of them they are taking over the flower bed.

Is that what they do? Can I split them (dig some up and move them?)

    What a bargain! They look great but if they increase in number again next year it will be too many.

    Runners? Guess they are running under the surface (like strawberry plants? you can tell I am a novice).

    If I remember correctly, rudbeckias die back after autumn (last winter I thought they'd died) so do I need to be doing my splitting sometime soon? I'll keep an eye open for runners.

    Thanks, verdun

    Can I but in with a rudebeckia question, please?

    What is the ideal situation for them. Mine is doing ok but seems to suffer in the sun. It goes floppy. Would it be better in the shade or does it need sun and lots of water?

    Near my rudbekias, which have come back for the second year and look good (but not prolific like yours) are some verbena bonariensis which I planted last year.  They have popped up all over the bed this year so like you, I am wondering what to do with the self-seeders because I don't want a bed of solely VB.

    I think this demonstrates that, as Verdun says, if a plant is happy, it will proliferate.  On GQT this week, they said that it's difficult to propagate VB so I feel blessed but since that is their happy place and I don't want many more of them, I'll prolly grow on the youngsters and give them to friends and neighbours.

    My rudbekias are getting tons of sun and not much water and seem to be surviving but not self seeding like AlexX's.  They're on fairly deep, enriched (but hardly!), clay soil in a South facing

    island bed.  Hope this helps and wish this forum wouldn't do whatever it was it just did!!

    VB are lovely - and I can recommend the verbena rigida ( like VB but much shorter). Isn't the colour fantastic?

    My rudbeckias are also in clay soil, south facing. It's a bed that can turn into concrete in dry weather - but we haven't had a lot of dry weather for the last 6 weeks. I bought 2 plants last year - now I have a half a metre bed. I said it was a bargain
