Question about Black Eyed Susans??

jdreams76August 15, 2008

I have coneflower and black eyed susans spreading around my garden.. Now do they do this so early in the season. When i say spreading i mean they are little seedlings of this stuff in different parts of my garden. Anyone had this happen?? And is there anyway to control it ?? I have been just digging them up and hoping that i am right and they are one or the other. Certianly look like the rest of the stuff all over my garden. And this happend to me last year. So just wondering :) Thanks, Kelly

Kelly-Rudbeckia hirta is the annual kind you're looking at and it does spread around promiscuously, for sure. If you have an interesting form, like Prairie sun or Summer sun, just let them go and remove as many as you can to control them. But, if you just let them go you will have one giant garden of yellow.

Rudbeckia 'Goldsturm' travels by underground runners as well as reseeding itself. It's a chore keeping it under control. I dug up tons of plants this spring and gave them away. Now there are more than I had before. Arghhh! They sure are beautiful this time of year though.

The simplest way to avoid plants re-seeding is to deadhead the flower before it sets and disperses seed.

Ours seem to stay put pretty well, but that may be because we have them hemmed in by some pretty deep garden-edging stuff. Still-- they're lovely and they are pretty pest-free. I'd just let 'em spread!
