Longest blooming perennials
Suppose you want to make sure that there's always flowers blooming somewhere in your yard with limited space, you can plant at least a few "anchor" perennials that are long blooming.
I was looking through and notice the long blooming plants were:
Corydalis Lutea (yellow Corydalis) - blooms for 20+ weeks from May to October.
Dicentra Luxuriant (Luxuriant bleeding hearts) - bloom for 17 weeks from April to Sep.
Tiarella Iron Butterfly (iron butterfly foamflower) - bloom for 14+ week from May to Aug.
Tradescantia Virginia (Concord grape spiderwort) - bloom for 12+ week from May to Aug
Salvia Superba (meadow sage) - bloom for 12+ weeks from May to Ocxt
