Spotted Joe Pye Weed

Spotted Joe Pye is a striking that grows tall with sturdy stems that rarely need to be anchored. The purple-speckled stems are nearly the same colour as the dusty rose-colored blooms, which bloom from midsummer to early October. Because it self-propagates well, it should be planted with caution in small landscape contexts. This is a tough, good-looking plant that blooms in late summer and early fall in the northern half of North America, reaching a height of five to six feet.
