Summary
Scarlet paintbrush is one of the most widespread and visually striking paintbrushes in western North America, known for its tall stature and vivid scarlet bracts. Although its corollas are edible, this species frequently grows in montane soils that may contain selenium, making consumption minimal and cautious.
Physical Characteristics
Castilleja miniata is a PERENNIAL growing to 0.8 m (2ft 7in) by 0.5 m (1ft 8in) at a medium rate.
See above for USDA hardiness. It is hardy to UK zone 4. The flowers are pollinated by Hummingbirds, bees, .
It is noted for attracting wildlife.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers moist soil.

Plant Habitats
Edible Uses
Edible Uses & Rating: Edible corollas may contain sweet nectar. Best rating among the four species, but still low-to-moderate due to selenium risk [2-3]. Taste, Processing & Kitchen Notes: Corollas have pleasant sweetness; bracts are resinous and bitter. Corollas can be used fresh as garnish. Nectar is best extracted by immersing corollas in water and reducing into a sweet infusion [2-3]. Seasonality (Phenology):Blooms June–August (earlier at low elevations, later at high). Harvest during open bloom.

Cultivation details
Growing Conditions: Found in moist mountain meadows, forest edges, riparian areas, and subalpine slopes. USDA Zone 3–8. Habitat & Range: Widespread across western North America: Alaska to New Mexico, especially the Cascades, Rockies, Sierra Nevada, and coastal mountains. Size & Landscape Performance: Generally 30–80 cm tall, spreading 20–40 cm. In gardens, thrives when paired with compatible hosts (e.g., penstemon, grasses, asters). Cultivation (Horticulture): More easily grown than many paintbrushes but still host-dependent. Requires well-drained soils with consistent moisture. Identification & Habit: A perennial herb 30–80 cm tall, with broad, lanceolate leaves that may be slightly lobed and a dense spike of bright red to orange-red bracts. Stems are upright and often numerous. Flowers bloom from early to mid-summer.
