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.
