Why go to the bother of collecting all those tiny seeds? The first reason is thriftiness. No need for anything in your garden to go to waste. Compost, recycle, and re-use. The second reason is frugality. Why buy new plants every year when you can grow your own for free? Even further, why buy unproven plants or seeds when you know the ones you are collecting from did well and obviously flourished in your yard.
Another reason to collect seeds is to ensure the propagation of heirloom varieties and rare, native plants that are not available through other means. Commercial growers and catalogs will often only carry the most popular plants and seeds. By collecting seeds from particular flowers and edibles, you are safe-guarding the future of these species. You are guaranteeing we will have a wide variety of genetic diversity in our future and not just the current “top growers.”
The final reason to collect seeds is to trade them. You may have 100s of Cleome seeds and another gardener has 100s of Poppy seeds. Why not trade a few hundred with each other? Again, you are getting new plants for free or close to it. Seed trading is a whole world unto itself. There are online groups, pen pal lists, and clubs for seed swapping.

Neighborhood: Fort Totten
From the Fort Totten metro station, walk to the left (north) out of the station and then turn left (west) down a paved path across a grassy field across from the parking lots -- you'll see the garden just over the crest of the hill.
