I'm still waiting for my seedling to bloom. I believe the flowers are pink. Usually, Echium seeds are extremely easy to grow from seed, and indeed self-seed, even in zone 5, however this seed was difficult for me. Only one germinated, while the E. vulgare and E. wildprettii in the same tray germinated in 2 days.
