Avalanche Lily, Erythronium montanum, blooms right after the snow melts, and in some meadows carpets the ground. The large, showy, white flowers become pink as they age. What we might call six petals are actually tepals, a term used when petals and the underlying sepals look the same. In many flowers, sepals are green, while some flowers have only sepals. Avalanche Lily has three petals and three sepals (slide 12).
