The Native Plant Store can Now be Found Here

  • This page will remain accessible as a library page until I have all the species moved to the new page and all the quirks worked out in the new software so it can function as a searchable library.
  • Please see the Using the Plant Library  page  for some tips on how to make the most of the information in this existing library to select species for creating a healthy native plant community suited to the conditions of your site.

~ Parthenium integrifolium, Wild Quinine

Parthenium integrifolium

Wild Quinine

  • Average to moderately wet or moderately dry soils
  • Full sun 
  • Up to 4’ tall, 12” to 24” wide
  • Summer blooms followed by persistent seed heads that look the same as the blooms
  • Native to the mid-west and the Carolinas, Thrives in Meadows 

A very long blooming species, these have been growing in the spaces that I tend for a few years and have proven to be perfectly winter hardy for the Ottawa and Perth area.

They are a food source for a variety of pollen and nectar feeding insects, including beetles. They aren’t the fastest species to establish but they seem to be very long lived and are slow to spread. They seem to be quite drought tolerant.

Prairie Moon has a profile on them here and the Xerces Society has a profile on them here
