Aurora Deep Purple Delphinium

Aurora Deep Purple Delphinium (Delphinium 'Aurora Deep Purple')

Aurora Deep Purple Delphinium is a sturdy elatum-type selection producing tall spires of rich, saturated purple double blooms in early summer with a possible late-season repeat. Upright clumps with strong stems bring vertical emphasis and classic cottage-garden presence to sunny borders.

Distinctive Features

Uniform spikes on robust stems resist flopping better than many delphiniums, delivering densely packed florets with long vase life. Refined foliage forms a neat base that showcases the flower towers.
