*Heirloom* (I. purpurea) Now famous as the variety that set the Whealy’s on their path to eventually found the Seed Savers Exchange, Grandpa Ott’s is a real beauty. Of Bavarian origins, its purple trumpets have glowing magenta centers and a dark five pointed star pattern. Climbs over 10’ in a season with trellising and is covered with blooms until frost. May self sow but not in a “hell-bent on world domination” way, like some of its weedy relatives. 70 days. UO
Note: May self-sow but they have not been aggressive for us. If you are concerned, deadhead often! To aid in germination, nick the seeds and soak overnight before sowing.
