Digitalis ferruginea, also called rusty foxglove, makes very long spikes covered in small bell blooms in creamy yellow flecked with rusty brown.
Sow on the surface and press into soil, as seeds need light to sprout. Sprouts in 14-21 days at 65-70ºF. Start indoors 8-10 weeks before last frost, then plant outside after frost 12 inches apart.
