A drought-tolerant perennial native to western North America with distinctive large, arrow-shaped basal leaves and cheerful yellow daisy-like flowers in spring. Excellent for dry gardens, meadows, and hillsides.

Why grow it

Arrowleaf balsamroot stands out among spring-blooming perennials for its ability to thrive in poor, shallow soils where many competitors falter. Its large basal leaves emerge early and persist through summer, providing visual structure after flowering, while the deep taproot makes it exceptionally drought-resistant once established. This combination makes it particularly useful for stabilizing eroded slopes or filling dry meadow gaps where establishment of other natives can be unreliable.

Watch out for

Plants take several years to reach mature size and flower reliably, so patience is needed during establishment. The large taproot makes it sensitive to transplanting and difficult to divide, so direct seeding or purchasing young plants is preferable. In areas with adequate summer moisture, vigor can become uneven or the plant may decline, suggesting it performs best in genuinely arid settings rather than merely well-drained garden sites.
