Description
Huge, dinner plate sized flowers sit atop robust, shrub-like plants from mid to late summer. ‘Blue River II’ is long-blooming. Each successive spring will bring larger flowers. This variety produces pure white flowers with no contrasting eye.
The foliage of ‘Blue River II’ bears a hint of blue, giving the plant an overall cooling effect, great for those hot summer days in the garden. It’s hard to believe this tropical-looking beauty is hardy to zone 4!
‘Blue River’ is the result of a cross between H. militaris x H. moscheutos and was introduced by Dr. Harold F. Winters. H. militaris was found growing along the Blue River in southern Oklahoma, hence the name.
These North American native plants bring massive, tropical-looking flowers all the way to zone 4. Although later to emerge than most perennials in spring, these are fast growing plants capable of adding an inch of new growth a day. Excellent at brightening up end of season gardens.
