Facts About

Accepted Synonym: Hexalectris warnockii

Bletia warnockii, the Texas Purple Spike, is widely scattered in Texas and reaches its northern limit in Arizona and extends its range far to the west in Baja California, Mexico. This leafless orchid has a reddish-purple stem that supports 3-10 flowers of a similar color. The labellum is 3-lobed with heavily veined purple lateral lobes and a central lobe that is mostly white with a purple spot at the apex and ridges that are bright yellow. This orchid grows in the moderate to heavy shade of oak woodlands, often among rocks or near fallen logs.

Bletia warnockii is considered imperiled, although information concerning its distribution is incomplete. Individual plants usually do not bloom in successive years and may remain belowground for several years. It does occur in Big Bend National Park where its habitat is protected.
