Tigridia is an easy-to-grow summer blooming perennial bulb. The showy flowers have six petal-like tepals that are white or a vivid solid color—orange, pink, red, yellow. The blooms make a somewhat triangular outline.
Tigridia has several common names including tiger flower, peacock flower, and Mexican shell flower. The Latin name tigris refers to the centers of the blooms which are prominently spotted. That is a reference to the Central American tiger known as the jaguar. Tigridia is native to Mexico and Guatemala.
Tigridia flowers last just one day, but flowers appear on the plant in succession over several weeks. Flowers are borne on stems above fans of lance- to sword-shaped leaves.
