What is the bloom time of the Lily-leaved Twayblade?

May to July is the bloom time of the Lily-leaved Twayblade (Liparis lilifolia).

Specifically, this wild orchid blooms from late spring into mid-summer. It may be easy to miss since the plant often does not reach the upper limits of its mature height of 2-10 inches (5.08 - 25.4 centimeters). But the plant's dainty bloom nevertheless welcomes visitors of stream bank and woodland habitats.
