Also known as Golden Garlic. It is native to the Davis Mountains of west Texas. One of the brightest and most unusual spring-flowering North American alliums, it is becoming endangered by livestock overgrazing. In garden cultivation, the golden garlic will occasuionally extend its flowering season into the summer if precipitation and sunlight are to its liking. It requires spring moisture and careful summer watering.
