I bought this online from Crocus and the leaves had a slight white tinge as if a fertilizer had been put on them. It was ok for a couple of weeks then…
It will grow better in full sun and will tolerate a little light shade. It might need some staking if it has heavy blooms. This is a vigorous spreader.
By seed or by division in the spring.
