The lemon lily is a bulbous herbaceous perennial that produces showy, fragrant yellow flowers during the months of July to August. These flower are large, with red spots in their corolla throats. In California, populations numbering in the thousands are found in high-elevation meadows and smaller populations occur in canyon with perennial water. Yet in Arizona, small populations, most numbering less than 100, are found along wet canyon bottoms near perennial water.
Distribution & Occurrence
Occurs along streamsides in canyons and wet meadows at 1700m - 3000 m in elevation. Soil is high in organic material and remains saturated throughout most of the year. (Arizona Game and Fish Department 1999)
|7 populations, 6 of which are stable in Ramsey Canyon|
Conservation, Ecology & Research
Herbivory may also be detrimental to flowering plants.
Pollination is by hawk moths (Hyles lineata and Sphinx perelegans) in California. Pollinators are unknown for Arizona plants (Newman 1992).
Small population size
(Arizona Fish and Game Department 1999)
Suggested management projects include moving trails away from populations and obtaining water rights on land where the species occurs to ensure that hydrology is not altered.
