This is perhaps the most beautiful of all American lilies. The, 2-6 feet high with arranged in whorls, carries scented, funnel-shaped blooms on oblique, upward-slanting pedicels. The pale-yellow , usually between one and 15, but occasionally up to 50 in number, are spotted brown, with the lower half of each segment incurved and reflexed. Usually found in southern California and Arizona at 6,000-10,000 feet, mostly on granite soils and in situations where the bulb is covered by ice and snow for half the year. Difficult to raise in cultivation; must have free-draining soil consisting preferably of two to three parts of -mould and peat mixed with stone chippings and charcoal. Bulbs should not be planted too deeply, and preferably in situations where the base of the plant is not exposed to full sunlight. Water requirements are unusually heavy during growth but, as soon as flowering has ceased, bulbs should receive surface protection from rain until the onset of frosts.
L. parryi var. kessleri is from the San Gabriel Mountains in California, and is hardier than typiami. (NALS-LYB 1958)
Hybrid production especially with L. pardalinum, L. helloggii, L. humboldtii, and L. ocellahim (Bellingham hybrids).
