Silphium laciniatum, Compass Plant

Silphium laciniatum

Compass Plant

  • Full sun
  • Average to high moisture soils
  • 5’ to 8’ tall, 3’ to 4’ wide
  • Summer to early fall bloom
  • Ontario Native, Good for meadow or garden settings. Very long lived 

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

Slightly shorter than their close cousins, Prairie Dock, these are still very large herbaceous plants. Their common name comes from a tendency for their leaves to be oriented on a north-south axis along the upright blooming stems. Given their stature and the fact that they are known to live upwards of 100 years, carefully consideration is recommended when selecting a location for one of these.

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

Pickups will begin the following week.

I will be offering plug sized plants for $1.25 each or 5 for $5. 

I'm in the process of adding species that I expect to offer this spring to the listings since they are starting to germinate and I'm starting to get an idea of which will be available in abundant quantities.

Since the list is much longer this year I've added several categories to help narrow down your options based on a variety of criteria.

For those who have already adopted seedlings, planting instructions can be found here.
