Flowers of calochortus ambiguus
are very pretty, showing the three-fold symmetry and striking colors typical of all members of this genus. Most of each petal is pure white (occasionally tinged light pink), but towards the base is a thin band of dark red-brown (sometimes not continuous), then a wider strip of greenish-yellow with prominent yellow hairs, and finally a purplish patch at the base. The six thin stamens are white, topped by purple-maroon anthers, while at the very center is a pale-colored, three-pronged structure. The grass-like leaves grow at the base, and wither away by summer.
