Silvery lupine
Lupinus argenteus
Silvery lupine is a hardy native wildflower that prefers full sun to partial shade and well-drained, sandy or loamy soil — it fixes atmospheric nitrogen and naturally improves soil health. Once established, it is relatively drought tolerant and requires minimal supplemental watering. Avoid overwatering or heavy clay soils, as these conditions can cause root rot.
