Grew these for the first time this year. Beautiful when mass planted together! Especially next to Calendulas. The seeds germinated really quickly and were easy to grow. Here in the PNW (Zone 7b), they held up great in the spring and summer, very hardy & drought tolerant but they ended fast in the rainy autumn weather. I noticed that the slugs never ate them, even as seedlings.

A fun little flowers to grow! I paired them with Johnny jump ups, both look great together. Very pretty blue& easy to grow.
