How to Plant Angel Trumpet Seeds

Angel’s Trumpet is the common name for plants in the Brugmansia or Datura family. While Angel’s Trumpet plants started from cuttings are more common, you can sometimes find its seeds as well. Here is how to plant Angel’s Trumpet seeds.


  1. 1
    Prepare a potting mix.
    • Use sterile seed starting mix.
    • Moisten the mix with water until it holds together.
  2. 2
    Fill new or thoroughly cleaned pots or flats with seed starting mix.
  3. 3
    Plant seeds 1” (2.5 cm) deep, one to a pot, or 6” ( 5.2 cm) apart in flats.
  4. 4
    Enclose pots or flats in clear plastic bags or use a plastic flat cover.
  5. 5
    Provide bottom heat by setting the planted pots or flats on a seed starting mat.
  6. 6
    Keep the pots or flats in a sunny, warm room, heated to about 75ºF (23.8ºC).
  7. 7
    Keep the seed starting medium moist at all times until seeds sprout.
  8. 8
    Remove the plastic covers when the seeds sprout.
  9. 9
    Allow the seed starting medium to dry out slightly before watering after the seedlings sprout.
  10. 10
    Fertilize the seedlings with a houseplant fertilizer at half the strength recommended when the seedlings have one set of true leaves.
  11. 11
    Transplant seedlings out of flats into pots when they have two sets of true leaves.


  • Angel’s Trumpet may take a year or more to bloom from seed.
  • Provide good air circulation in the room where you start the seeds to prevent dampening off, a soil fungal disease that kills seedlings.
  • The first set of leaves to emerge are called seedling leaves and often don’t resemble the mature leaves. The second set of leaves will look different and those are called “true” leaves.
  • Look for seeds online or ask friends who have plants outside to save any seeds that form for you.


  • All parts of this plant are poisonous.
  • Do not use a regular heating pad for bottom heat to start seeds. This can start a fire and is generally too warm for the seeds.

Things You’ll Need
