Tecophilaea cyanocrocus, the Chilean blue crocus, is a flowering perennial plant that is native to Chile, growing at 2,000 to 3,000 m (6,600 to 9,800 ft) elevation on dry, stony slopes in the Andes mountains.

The single flowers are approximately 1 in (2.5 cm) across, goblet shaped, and are an unusual deep gentian blue color, with a whitish center.

[2] The genus Tecophilaea was named after Tecofila Billiotti, botanical artist and daughter of the botanist Luigi Aloysius Colla of Turin.

By crossing these with each other and with the solid blue type form, other cultivars such as 'Storm Cloud' have been developed in recent years.

Where winter freezes may occur, such as the Pacific Northwest, tecophilaea is best grown in containers that can be protected from very cold weather.

The corms go dormant during summer, and water should be entirely withheld once the foliage fades after the springtime period of active growth.

When active growth begins in the fall, tecophilaea will benefit from being fed with a dilute solution of a low-nitrogen fertilizer once every week or two.
