Triteleia is a genus of about 15 species of cormous perennials, all of which are native to western North America. They are grown for their showy funnel-shaped flowers which bloom in umbel-like inflorescences atop leafless flowering stems in spring to early summer. Each flower consists of three petals, three petal-like tepals, six stamens and a 3-lobed stigma atop a single 3-chambered ovary. Triteleias grow from underground corms which last for only one year, but are replaced each year by new corms that develop from fall to late spring. Plants go dormant in summer after bloom.
