Blooming at 33" around June 7 in my garden two years after planting a rhizome from Mid-American, 'Flash of Light' is not subtle.
From Mid-America's website:
(T.Johnson '08) From the centers of dark blue falls comes a blazing flash of white light. Ruffled white standards have just a hint of blue around them. Dark violet-blue falls shade inward to dazzling white sunbursts illuminated by bright gold yellow beards. Super show branching and double budded sockets in a color & pattern normally shy of buds. Makes very showy clumps. Vigorous healthy growth. Late 36” (91cm) Sdlg. TX49B: Snowed In X Queen’s Circle
