In my experience, Allium falcifolium, Allium siskiyouense, and Allium bolanderi are not aggressive seeders. Allium hyalinum increases rapidly by offsets and I would not recommend it if you want to keep it to a small space, but it did not seed much in my garden. Allium oreophilum, an Old World species, might be suitable. There was a pink-flowered species that I received from the Robinetts under what Mark McDonough felt was the wrong name, and it became quite a pest; I'm still not sure what it is, but I did not bring any from the old garden (which is now owned by people who like native West Coast plants and are not particular about confining them). There are also some western American species that I classify as "middle-sized" (in flower, more than 10 cm and less than 30 cm tall). Allium peninsulare and the similar Allium crispum do not increase much. Allium douglasii is perhaps too aggressive here. For Travis's area in southern Oregon I would stay initially with the western American species, of which there is a very large number. There are some notoriously weedy species among the Old World contingent. Search, and perhaps ask here, before turning them loose.
