Seed collection is a great, low-cost method for garden expansion. While collecting and propagating seeds requires time and patience, the results are rewarding whether you collect from your own garden or a friend.
When collecting, look for ripe seeds that pull off the plant easily and have turned from green to brown or black. Seed pods or sheaths will often have a dry, crunchy and brittle texture. Use a brown paper bag or other breathable material to collect as it is best to avoid plastic bags or containers without ventilation as these will trap moisture.
As you are collecting, please be mindful of the small birds and mammals that rely on seeds from native grasses and flowers for winter food. To keep these critters fed, it is recommended to only harvest 20 percent of available seeds.
To clean seeds, remove the dry protective covering or chaff and store them in a cool, dark, dry place such as a refrigerator.
Many plant seeds don’t require treatment to break dormancy, however, some species do require treatment. The most common methods include:
Clockwise: Desert Blue Star seed, Northern Sea Oats seed, Chocolate Flower seed and Little Bluestem seed.
Scarification – crack or abrade hard seed coatings
Stratification – cold, moist conditions
For tips on planting seeds, Fort Collins’ Gardens on Spring Creek offers an online resource that relates to common native plants. Seed stratification can be done by seeding into containers and placing them outside during winter.
