About Desert thornapple
Datura pruinosa, commonly known as Toloache, is an annual or short-lived perennial plant native to North America, valued for its large, trumpet-shaped white flowers that open in the evening and night, releasing a sweet and intoxicating fragrance. Its grayish, velvety foliage gives it a distinctive appearance, making it ideal for moon gardens, large pots, or as a focal point in flower beds where its spectacular blooming can be admired.

Care tips
It requires full sun for abundant flowering and well-drained soil, preferably sandy or loamy-sandy. Watering should be regular during the growing season, keeping the substrate moist but not waterlogged, and reduced in winter if the plant persists. A common mistake is underestimating its size, as it can become quite large and require space or staking. The entire plant is toxic if ingested.
