Star-shaped white flower at the end of a slender naked stalk that arises from the leaf joint at the top of the plant. Individual flowers are ½ inch across, have 6 to 8 petals, with 7 petals most common, and yellow-tipped stamens that turn brown with maturity. One plant commonly has 1 or 2 flowers.
Leaves and stem:
5 to 9 leaves (commonly 7) of unequal size are in a single whorl at the top of the main stem, just below the flowers. Leaves are up to 4 inches long and 1¼ inch wide, toothless and hairless, with a pointed tip and tapering at the base. There may be a few small leafy appendages alternately attached on the otherwise naked main stem.
Starflower tends to grow in colonies. Formerly known as Trientalis borealis and in the Primulaceae (Primrose) family, it has been shuffled around to new species name Lysimachia borealis (same genus as the yellow Loosestrifes) and moved to the Myrsinaceae (Myrsine) family.
