  • This page will remain accessible as a library page until I have all 200+ species profiles added to the new store software
  • Please see the Using the Plant Library  page  for some tips on how to make the most of the information here to select species for creating a healthy native plant community suited to the conditions of your site.

Polanisia dodecandra, Clammy Weed

Polanisia dodecandra

Clammy Weed

  • Annual 
  • Full Sun
  • Thrives in dry soils
  • Grows 2’ or more in height and width
  • Summer blooming
  • Native to Ontario, thrives in dry, sunny conditions and low fertility soils

New to me this year, grown from seeds from Prairie Moon Nursery 

https://www.prairiemoon.com/polanisia-dodecandra-clammy-weed-prairie-moon-nursery.html 

This is a bushy annual species that, to my eye, bears a strong resemblance to Cleome, the showy annual species also known as Spider flower. Which isn’t surprising when I check their family tree, which places them in the same tribe as that, also native to this continent, species.

While they naturally thrive in open, dry locations, I’ll also try growing a few of these in containers this year, in my ongoing project of finding how well a range of native annual species adapt to container conditions.

Please check out the Prairie Moon listing at the link above for more details.
