This short-leaved lomatium is a native Pacific Northwest perennial best suited to rocky, well-drained soils in open meadows or woodland edges with partial shade. It is a low-maintenance plant once established and requires minimal supplemental watering, particularly in its native range. Avoid overwatering and heavy clay soils, as good drainage is essential to its long-term health.
