can I prune Green Coneflower in order to stimulate more flowers?

Lynn NevinsAugust 29, 2010

This is my first year with green coneflowers so I'm not sure how much longer their growing season is but....most of the flowers that were on there are pretty 'spent'....all their petals are gone. Is there such a thing as pruning this plant, say just below a joint that produced a flower, in order to stimulate the growth of additional/new flower-producing stems for this season?

And if so, and I want the self-seeding to proliferate, would I take any of the spent flowers that I DID cut off, and leave them on the ground so that the seedheads can dry up and spread themselves as they normally would later in the year?

If you want viable seeds, you will need to let the seeds mature *on* the plant - no cutting off early. If the seeds mature as they are meant to, the plant will not push other flowers.

I have not grown green coneflowers so someone can correct me if I'm wrong, but I do not think dead-heading will encourage a new flush of flowers with this plant.

Just curious. What is green coneflower?

I assumed the OP meant green-headed coneflower or Rudbeckia laciniata but they could have meant something else.

That looks like R. laciniata to me. I have some growing wild. I tried to tame it but it goes wild in my garden on me!
