Wildflower that looks more like scabiosa than fellow knautias to me - but it holds its pincushion flowers up on taller stems. Nice.

Visitors to this page have left the following comments| Chris Maciel | May 11, 2008 | It's great finding someone like you who likes to share his garden. For me, it's specially helpful that you show a wide view of the area where any particular plant is growing as it helps to know where to use a plant, always a question. Your photographs are very good and the identification of the plants always proper.
Thanks. |
| Mike | Nov 23, 2009 | Nice looking plant- flower looks like Monarda villosa, but it is considered a regional noxious weed in British Columbia. One plant can produce 2000 seeds! http://www.agf.gov.bc.ca/cropprot/weedguid/scabious.htm
I included the link so gardeners can see what other common plants also have invasive tendancies.
Thanks for the reference, Mike. It's funny how things vary regionally - this plant has expired from our garden, so it was none too vigorous around here... |
| Missy | Jul 18, 2012 | I transplanted Knautia seedlings and they are growing so slow. Only about 6 inches tall after 3 months. Is that normal? Will they bloom this season?
Yes, that's perfectly normal. They won't bloom this year, but should grow robustly and bloom next spring/summer. |
- Seed from '02 trade. Baggy 70F (70%G, 7-16d)
- Same seed as above. Baggy 70F (30%G, 10-28d)
