Botanical name: Eschscholzia californica • Bloom season: Spring to summer‍ ‍• Bloom color: Orange‍ ‍• Host plant (elsewhere in North America): Mormon metalmark, dotted blue, Plebejus acmon, Plebejus neurona

Silky orange cups on blue-green, finely divided foliage, opening with the sun and closing in the evening and on overcast days. It has no nectar at all; rather, it is a pure pollen flower, and native bees work it heavily for exactly that. Sown thickly, it produces stunning sheets of orange.

Growing Notes

Full sun and average garden soil with regular water. Plant out after the last frost. Space about 12 inches apart. It sulks in the worst of a Reno July and then comes roaring back as the nights cool in September, so do not judge it by August.

Maintenance

Deadhead relentlessly; this is the one plant here where the maintenance and the performance are the same thing, because it stops flowering once it sets seed. Cut it back by a third if it gets leggy midsummer and it will refresh. It self-sows moderately, and the volunteers are welcome in most gardens.
