The lovely and choice (and not at all invasive) Californian hound’s tongue. The flowers are pinkish or purple changing to blue as they age with a prominent white eye, like a small blue jonquil. The foliage is broad and emerges maroon turning to soft green and not at all coarse.
This species is basically a woodlander in the wild. Like many Mediterranean climate plants it comes up in winter and flowers in spring so is better with shelter from the worst of the weather. It goes dormant in summer so could be a good one for dry shade. Protect from slugs.
