The Plant store is now closed for orders.

  • I'm planning on one last round of sales toward the end of September of plants that I'll be potting up from a nursery bed I planted in the fall of 2022. I'll post the details and the time once I have the plants ready to go
  • 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.

Agastache nepetoides

Yellow Giant Hyssop

  • Average to moderately dry or moderately wet soils
  • Full Sun, light shade
  • 5’ to 6’ tall, 18” to 24” wide
  • Late Summer to Fall Blooming
  • Ontario Native Species, Beginner friendly, thrives in Meadow, Open woodland and Dry meadow ecosystems. 

Still new to my garden (last year’s seedlings are still small) I’ve started some for this spring with seeds from the Ottawa Wildflower Seed Library.

Like most, if not all, Agastaches these are very popular with pollinators offering a very long blooming season in later summer with plentiful nectar for bees and butterflies preparing for travel or overwintering.

Recommended for dappled shade settings, these will also do well in full sun if sufficient moisture is available. A large species for the back of a garden border, as a focal point or as part of a tall meadow community.
