About Desert thornapple
Datura discolor, also known as desert thornapple or desert trumpet flower, is an annual or short-lived perennial plant native to the desert regions of North America. It is characterized by its large, trumpet-shaped white flowers that open at dusk, releasing a sweet fragrance, and its grayish-green leaves. It is ideal for dry climate gardens, rockeries, or large pots where its nocturnal blooms can be appreciated.

Care tips
This Datura thrives in full sun and well-drained soil; overwatering is its main enemy. Water moderately, allowing the substrate to dry out completely between waterings, especially in arid climates. Use sandy or cactus-specific soil to ensure good drainage. A common mistake is overwatering, which can lead to root rot.
