Sulphur indian paintbrush have colorful white bracts surrounding a greenish-white flower.
Castilleja, commonly known as paintbrush, Indian paintbrush, or prairie-fire, is a genus of about 200 species of annual and perennial herbaceous plants native to the west of the Americas from Alaska south to the Andes, northern Asia, and one species as far west as the Kola Peninsula in northwestern Russia.
Castilleja are food source for pollinators including butterflies and hummingbirds.
The roots of Castilleja species tap into the roots of a host plant for survival. It is hemiparasitic, obtaining water and nutrients from other plants by tapping their roots. Grasses and sedges makes good host plants. Plants should be planted at the same time, or if the host plant is already established the seeds can be scattered at the base of the plant if the lower part of the plant is slightly bruised (knife works well).
Type: Hardy perennial
Hardiness zones: 4-8
Height: 30cm, 12"
Location: Sun to part shade
Seeds per packet: 10
Sow just under the surface of the soil and water in. Leave them at room temperature for 6 weeks. This helps break the phytohormones which inhibit germination. They will not grow yet. Then a cooling period is required. Cover them with plastic and place in a fridge for 80 days. Be sure they stay moist. After the cold stratification period they are then brought back to a cool room (15-18C, 59-68F) for them to germinate. Germination can be erratic, generally 30-90 days after the warming period for most seeds, though some can take longer.
