UNDERSTANDING Giant Coneflower.....
I have several clumps of rudbeckia maxima in different gardens. This early summer we had some heavy storms and I found numerous stalks that fell over. I took the uprooted stalks, applied root hormone and potted them up. The original stems stayed green for a while, then turned brown, BUT at the base of one pot, new sprouts grew. Hooray!. The other pot, rooted I believe, but the original also turned brown. Is this the nature of the plant? This years stems decline at the end of the season and then new sprouts develop. I have a healthy clump that looks pretty rough every season this time of the year, then spring comes and they are beautiful? Can anyone comment on this plant's reproduction, propagation etc.?
Thank you for your time. :-)
