We have both flower seeds and vegetable seeds.  Many wildflowers make wonderful ground-covers for bulbs during their dormant stage.  With the right combination, you can have year-round flowers!  Here you can find good prices on moderate amounts of bulk seeds which the average gardener can put to good use.  Among other things, Alyssum, California Poppies, Dichondra and vegetable seeds are available by the ounce.
