Botanists have ranked the Sierra Nevada alpine zone floral bloom as one of California's foremost wildflower displays, with flowers of fantastic color and abundance. [8] Many of the alpine species are notable for large and showy flowers, which must compete for the pollinators during brief growing seasons. [5]
