Stachytarpheta jamaicensis ‘Blue’

Stachytarpheta jamaicensis ‘Blue’, commonly known as blue porterweed, produces long, slender spikes of small, vivid blue flowers from summer through fall. A true pollinator magnet, it draws butterflies, bees, and hummingbirds to the garden. Its loose, spreading habit and heat tolerance make it a great choice for sunny borders and pollinator gardens.
