Suggested uses include rock gardens, drought-tolerant gardens and borders. It is native to western North America and especially California.

About

Zauschneria cana is a perennial from western North America, especially California, adapted to dry, sunny sites. It prefers full sun on well-drained sandy or rocky soils with a neutral to slightly acidic pH. Plant in an exposed, south-facing position where soil moisture ranges from dry to medium.

In the garden

Zauschneria cana is a perennial native to western North America, with a natural affinity for dry slopes and exposed sites. In a UK garden give it a warm, south-facing position where it will receive full sun; it performs best where wind exposure and direct sunlight keep the canopy dry. The species is adapted to sandy or rocky substrates and tolerates neutral to slightly acidic conditions. Prepare a sharply drained planting hole or use a gritty, free-draining mix if potting; incorporate no heavy loam or water-retentive compost. Soil moisture should be maintained between dry and medium—avoid waterlogged ground. Position the crown at soil level and allow the surface to remain open to aid drainage in winter. Plants established in exposed sites generally need less attention than those in sheltered, damp corners. Use Zauschneria cana in rock gardens, drought-tolerant borders, or on gravel banks where its preference for sandy, rocky soil is met. A south-facing, exposed site will suit it best and reduces the need for additional watering in summer. For best results, plant where the soil is sharply drained and neutral to slightly acidic so conditions match those of its native habitat.
