I am no lily expert, but I had the privilege of assisting one, Edward McRae, in the preparation of his recent book "Lilies," and here is what he has to say about L. pardalinum 'Giganteum': "'Red Giant', the Sunset lily, was formerly known as Lilium harrisianum Beane & Vollmer. It has been treated either as a giant form of L. pardalinum or as a hybrid between that species and L. humboldtii. Beane and Vollmer described it from a wild population on the banks of Van Duzen Creek in northern California. ... This extraordinarily magnificent lily, usually 5-7 feet tall, bears large flowers, 3-4 inches wide, ... gleaming carmine-red inside from the tip to the midpoint, and chrome yellow from the middle to the base, tinged in the throat with green, with large spots, typically gold-ringed in chocolate brown." Regarding L. pitkinense, McRae writes, "Seedling populations of this species...showed enormous variation in height, flower size. color, and flowering season. They resembled a hybrid population more than a true species. This observation, coupled with the species' singular wild occurrence, suggests that L. pitkinense in fact represents a natural hybrid population. The plants were all strong and easy to grow, much like smaller forms of L. pardalinum." I grew 'Red Giant' for many years, having bought it from Russell Graham's nursery in the 1980s and planted it in moist woodland conditions. It can indeed get very large and has the long scaly rhizome Diana described. (L. pitkinense is also stoloniferous.) This discussion has stimulated me to make a trip to Eddie's nursery on the east side of Mt. Hood this summer and take some photos of these and other lily species for the wiki.
