Nemophila menziesii

Full disclosure, I never specified this plant on a project, so it is very unfamiliar to me despite being a California native species. It is rare for me to specify annuals on a design, since my focus rarely includes seasonal color. Now that habitat restoration and native species are not just trends but support a collective need, I am looking into species unfamiliar to me. On the home front, I am considering seeding N. menziesii to replace all the non-native Nigella that keeps cropping up every year. Both have pale blue flowers and are of similar size. So, what do the books and other sources say?

The first search popped up an all-women punk band from Japan, encouraging me to broadcast seeds more aggressively. Can you imagine? Blaring, heavy guitar action while gardening...does anyone do that? Seeds ordered. More to report on performance.... seeds, not the band.

My go-to website for natives is the California Native Plant Society's Calscape. Their website has a handy map that illustrates where various species were observed in the wild. For N. menziesii, or baby blue eyes (awww), the species appears to be widespread throughout California. Its sun exposure and watering requirements appear to conflict in references; where Calscape lists the species as requiring full sun to part shade and low moisture, Sunset Western Garden Book (2012) states the "plant is quickly killed by heat and humidity," while the reputable grower, Park Seeds, lists only part shade and moist conditions for its success. Has anyone out there planted this species in the Bay Area?
