INDIAN PAINTBRUSH Castilleja indivisa (Sorry no USA sales for this item)
Indian paintbrush is a hardy perennial with stunning colorful color that lasts for several months throughout the growing season! Plants form a nice clump, which requires very little attention, is drought tolerant, and disease resistant.
Type: Hardy perennial
Hardiness zones: 3-11
Seeds per pack: 5
USA restriction: These seeds cannot be shipped to the USA.
Germination: As with many perennial seeds, these seeds can benefit from a period of moist cold to help them break dormancy. This is done by giving them a cold 'winter' period (artificial or natural), and then a warming to simulate 'spring', and time to grow! Here's how this can be done:
Obtain a planting container that has holes in the bottom for excess water to drain. Place the seeds just under the surface of your growing medium, and water. Place your container in a cold area (but not freezing, perhaps a refrigerator) for 4-6 weeks. Once the cold period is completed, place the container at room temperature for them to germinate. Be sure to keep the soil moist during this entire germination period. Seedlings will sprout a few weeks after the warming period.
