Oh, no, all seed is ordered from the same spot. In the beginning of the catalog, they list all of the organic varieties for you, so if you want strictly organic, you can look at that list and pick your varieties there. After the list of organics, they have the main seed catalog. That is where they list all of the varieties they sell (organic and non), and give descriptions of each variety. The first organic list is just a convenience, and you use the same order form for either list, as far as I can tell.
At the back of the catalog is the Moose Tubers catalog of potatoes, onion sets, etc. Those require a separate order form.
Does that answer your question?
