About plant names...

Starflowers are native to wooded areas of North America. The genus Trientalis means “a third of a foot,” possibly a reference to the height of these diminutive plants: about a third of a foot (4 inches). Borealis means northern.

Identification: Plants are 4-8" (10-20 cm) tall. From 5 to 9 narrow leaves are arranged in a whorl around a stem, each leaf 1-4" (3-10 cm) long by ⅜-¾" (1-2 cm) wide. Leaves are light green, and may be smooth or have fine teeth. Usually one, or sometimes two or three flowers, each about ½" (1.3 cm) across, appear on each stem. Flowers usually have seven petals, sometimes 5 or 9. They are white, sometimes pink; stamens are yellow. Flowering is during May and June. The shape of the flowers is probably their most unmistakable feature.
