I have two clumps that grow bigger each year loaded with flowers. I swear one was red and the other blue (blau glocke) and now they are both blue. My nursery expert says she is doubtful so I bought a red one from her this year. Absolutely no doubt it is red. they are in sandy amended soil and get a fair amount of water where they are at the bottom of a hill I water regularly. Never tried seeds.

I would like to know more about sowing this plant. Is it true that it takes up to 18 months for the seeds to germinate?

When the flowers first open, they are vivid red. They gradually fade to a muted wine color.
