I live in the Pacific Northwest, but at 1600 feet elevation near Mount Hood, with well-drained mineral soil and about 45 inches of rain per year, usually none of it in the summer. Only part of my garden is irrigated during the dry season. Usual winter lows in the mid-teens F. Here are the bulbs that have naturalized in the garden to the extent of self-sowing or appearing to be so well settled that, should I abandon the garden, they would survive until smothered by native vegetation: Crocus tommasinianus, C. speciosus, C. vernus ssp. vernus and ssp. albiflorus, C. pulchellus (!), C. kotschyanus, C. ochroleucus (!!) Dichelostemma ida-maia Triteleia peduncularis, T. laxa Colchicum: all the larger hybrids, and a few small ones, notably C. procurrens Sternbergia lutea Puschkinia scilloides Chionodoxa luciliae (blue and white forms), C. siehei, C. sardensis Hyacinthoides non-scripta Asphodelus albus Paradisea lusitanica Anthericum liliago Anemone nemorosa, A. blanda, A. ranunculoides Iris reticulata Narcissus, all the hardy hybrids and, in the rock garden, N. rupicola, N. calcicola, N. triandrus Camassia quamash, C. leichtlinii, C. cusickii Cyclamen hederifolium, C. coum, C. repandum, C. pseudibericum Nectaroscordum siculum Allium membranaceum, A. unifolium, A. moly, A. neapolitanum Notholirion thomsonianum Cardiocrinum giganteum Veratrum californicum, Disporum smithii, Trillium ovatum, Dicentra formosa, Smilacina (Maianthemum) racemosum, S. stellata, and Maianthemum dilatatum are native to the site. Convallaria majalis Galanthus nivalis, G. plicatus, G. 'Atkinsii', G. fosteri In addition, many of the species Paeonia that are well established have self-sown a little, even P. lutea with its huge seeds, which must be moved around by squirrels.
