Silphium terebinthinaceum, Prairie Dock

Silphium terebinthinaceum 

Prairie Dock

  • Full sun, light shade
  • Average to moderately wet or moderately dry soils
  • 6’ to 9’ tall, 2’ to 4’ wide
  • Mid to late summer bloom
  • Ontario Native, Feature Plant

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

This species is one of the largest for a prairie setting, with huge leaves and bloom stems that can extend above other tallgrass prairie species, like Big Bluestem. They are slow to mature, drought resistant once established and not easy to move because of the mass of their root system and overall size. A striking, long-term addition to an ecosystem, they should be placed with the same type of attention to their mature size as shrubs or small trees. 

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