Prairie Dock produced a lot of seed. It’s unusual for the finches to leave me enough to collect. The ray flowers of the Prairie Dock are the only part of the composite head to produce seeds. The seeds are the broad, flat objects arranged around the outside of the central disk.
Pale Indian Plantain, Cacalia atriplicifolia has some nice large seeds. This is an interesting plant that’s easy to grow from seed. Given minimal care, this plant can exceed six feet in height. The blooms are highly favored by wasps and attract a variety of species.
Tall Boneset produces huge masses of seeds. You don’t have to visit many plants to collect several thousand seeds.
I collect the entire Monarda seed head, let it dry completely and then shred it to release the tiny seeds.
The pods of the Wild Senna must be completely dried and then crushed to release the seed. I use a strainer to separate out the seed. A lot of seed is left in unbroken bits of the pod, so I save the debris and scatter it back out into the field.
False Gromwell has one of the neatest seeds around. These look like little jewels rolling around in the bottom of the collecting bucket. Seed characteristics are often used to identify species or varieties of plants. These seeds display a basal collar and surface pitting that distinguish the plant as Onosmodium molle var. hispidissimum.
