Henderson’s triteleia is a magnificent perennial wildflower found in dry foothill woodland, chaparral, openings in mixed evergreen forest, and on rocky slopes. Henderson’s triteleia has mainly yellow or sometimes white flowers with a dark purple or brown midvein and blue anthers. These flowering scapes have 2-3 narrow basal leaves and grow to about a foot tall. It blooms in late April to June depending on elevation and goes summer-dormant after flowering. Henderson’s triteleia has a restrictive range and is native to Siskiyou County in northern California and southwest Oregon up to Lane County. On a local level, within its range in southwest Oregon, Henderson’s triteleia can be quite common, but it is considered a rare species in California. Mature flowering plants may take several years when grown from seed. Henderson’s triteleia prefers sun to part-shade and well-drained soil. It is very drought tolerant and does not need any summer irrigation once established.
