Ask Mr. Smarty Plants

That is a lovely idea, nice for your guests and nice for the ecology. And since you are already working with invasives, you should be able to identify which seeds perhaps should not be presented to guests from certain parts of the country. In light of that, you might possibly want to have more than one packet or mix available for different parts of the country. So, for starts, let's look at your ideas for a more or less "universal" native wildflower.You can follow each of these links to get an information page on the respective plants.

Achillea millefolium (common yarrow) This found throughout most of temperate North America.

Geranium carolinianum (Carolina geranium) Again, grows just about everywhere in North America.

Silene antirrhina (sleepy catchfly) Shown on USDA distribution map as growing in all of North America.

Eupatorium purpureum (sweetscented joepyeweed) This is apparently found only in the North and Eastern part of North America.

Asclepias incarnata (swamp milkweed) The USDA distribution map shows this not appearing in the northwestern states, or Nevada, but does appear in California.

Chamerion angustifolium ssp. circumvagum (fireweed) THE USDA distribution map shows this plant distributed only in Washington State, Montana, Wyoming, Colorado and Minnesota, but does show up for all of Canada and Alaska.

Aquilegia canadensis (red columbine) Referring again to the USDA map, this plant only appears naturally from North Dakota south to Texas and to the East Coast.

You understand, I'm sure, that the fact that these plants don't show up in our Native Plants Database or in the USDA database as appearing in the states you are interested in doesn't mean they won't grow there. It just means those databases did not have that information. If you would like to widen your search, go to our Native Plant Database, down the page to the Combination Search. We tried this out using the choices of "All States", "herb" as the habit, "Annual" as the duration, and "6 hours or more of sun" a day for light. This gave us 150 possibilities. Depending on what states you expect guests from, you could do one state at a time, add in "perennial" on one choice, etc. The individual page on each plant in our database gives you the growing requirements of that plant, the states in which it is found, bloom time and bloom color.

Finally, go to our Native Plant Suppliers Directory and, again using the appropriate choices, find seed suppliers either near you or providing mail order services. You probably won't be able to find a pre-made mix of the exact plants you want, but since you can buy in bulk, you can break them down into custom mixes of your own for each guest.
