Specialize in milkweed seeds for raising monarchs. Our favorite is Asclepias curassavica ‘Silky Gold’ variety. (They are a bit pricey, so don’t forget to collect your own seed from your first batch!) See also Milkweed Propagation tips from Monarch Watch; interesting that they also recommend Asclepias curassavica for easy propation and maintenance.
A wholesale seed source for those really big jobs. Includes many grasses and wildflower mixes. Their offshoot Albright Seed Company has a slightly more manageable $50 minimum order.
