Overall: I originally grew this from seed and they grew quickly. They have managed to form tubers and survived 3-4 winters here in Berkshire. They are growing in a loam soil that is south facing so thats probably why. Sadly they dont sprout again until september. Ive sown some more so I can get them flowering earlier and dig the tubers up to get them flowering earlier. The shade of blue is indeed impressive. Be warned that if happy they will pop everywhere as they are very good at spreading their seed.
