Gardeners' Notes:

Excellent hollyhock. Soundly perennial; overwinters reliably in Zones 3 & 4; pest & disease free (no rust!); long season of bloom summer well into autumn. Also known as "Russian Hollyhock". Self sows if allowed but never a problem. Have had a nice colony here for 10 years+.

I actually paid for a plant of this species and am glad I did. It is a lovely addition to my growing collection of hollyhocks

I have had luck winter sowing this plant. I look forward to seeing it in bloom.
