The flowers are white[5][7] or pink[5] flowers are borne in April[5] or May.[5][7] Calyx (the collective term for sepals) is 5- to 9-parted and persistent. Corolla (the collective term for petals) is also 5- to 9-parted, rotate,[5][7] with a very short tube[7] and elliptic-lanceolate segments. Stamens occur in the same number as the corolla lobes (5-9)[5][7] and are positioned opposite them.[5] 1-3 Peduncles, 1-flowered, filiform, and ebracteate.[7] The ovary is one-celled.

Etymology

The former genus name Trientalis is derived from the Latin triens ('a third'), and is an allusion to the height of the plant, which is one third of a foot, or 4 in (10 cm) high.[5][9] Latifolia is derived from the Latin words latus ('broad or wide') and folia ('leaves') and means approximately 'broad-leaved'.[9]

The alternative name "Indian potato" refers to a small subterranean swelling at the stem's base, which is not listed as being edible by modern sources.[10]
