DOWNY PAINTED CUP

- / per
Castilleja sessiliflora is a species of flowering plant in the broomrape family known by the common names downy Indian paintbrush and downy painted cup. It is native to the Great Plains of North America from southern Canada, through the central United States, to northern Mexico. It occurs as far west as the eastern slopes of the Rocky Mountains.
This perennial herb produces one or more stems up to 35 centimeters tall from a woody root crown. 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).
This plant grows in several habitat types, including prairie, shinnery, Texas savanna, and shrubsteppe.
Type: Hardy perennial
Height: Up to 39cm, 16"
Hardiness zones: 3-9
Location: Sun to part shade
Seeds per pack: 40
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.
