About Thornapple
Datura ceratocaula, commonly known as thorn-apple or devil's trumpet, is a fast-growing annual plant, notable for its large, trumpet-shaped white flowers that open at dusk and emit a sweet, intoxicating fragrance. Its leaves are large and velvety, and it produces spiky seed capsules. It is ideal for night gardens, large pots on patios, or as a striking focal point in garden borders where its nocturnal bloom can be appreciated.

Care tips
This plant requires full sun for abundant flowering, though it can tolerate some partial shade in very hot climates. Watering should be regular and generous, especially during dry and hot periods, ensuring the soil does not dry out completely between waterings. It prefers a rich, well-draining substrate with organic matter, ranging from slightly acidic to neutral. A common mistake is underestimating its water needs; insufficient watering can lead to wilting leaves and reduced flowering.
