In my part of the world, winter has clamped down with snow and ice. Now, there are many ways to enjoy a home-bound day when the weather gives you pause to travel. And one of the nicest is to sit down with a garden or seed catalog, and if you've got a garden, plan it; and if you haven't a garden, then plan a game of "urban hobbitry."
"Urban hobbitry" is the practice of tossing native wildflower seeds into marginal areas: vacant lots, alongside irrigation canals, on the banks of urban streams and creeks. These areas are usually teeming with some kind of plant life (grass, usually, and perhaps a dandelion or two), there are usually critters around - why not support and enhance the diversity of the area with some native wildflowers? The critters love them; some birds and bess really depend on them; and you can never have too much natural beauty in these marginal, disturbed plots.
If you're interested in distributing a mixed variety of seeds, Victory Heirloom Seeds has a very nice selection of regional wildflower mixes.
Or, if you'd like to concentrate on just one type of wildflower, American Meadows let's you buy wildflower seed by the pound.
