The blue flowers of Large-flowered Triplet-lily are bell-shaped when open, and reminiscent of a gentian when closed, as most seemed to be on the plants I observed at around 4500 feet elevation on June 8 in the Boise Foothills. The flower has 6 tepals (typical of the lily family) – 3 inner and 3 outer – and 6 stamens.

The flowers of Triteleia grandiflora are in a terminal umbel atop a leafless stem, on pedicels which give the umbel a very onion-like appearance.
