“Royal blue, tubular flowers burst into bloom from green basal foliage for several months in late summer. Very adaptable in the garden and self-sows readily creating a lot of color and attracting pollinators later in the season. A hummingbird moth favorite and long-lasting cut flower.”
–Wild Seed Project
“Great blue lobelia’s flowers make great landing pads for our native bumblebees, never far away when this species is blooming. A versatile plant, this long-flowering summer perennial can stand moist to borderline-dry soils, and tolerates partial shade very well.”
