Datura plants, also called angel trumpets, have large, showy trumpet-shaped flowers that add interest to any patio or garden. Datura plants grow best in full sun, but can tolerate partial shade. With adequate water, Datura will grow up to 6 feet tall. If watered less, they will grow to about 3 feet in height. The large flowers are fragrant, and often bloom during the night. The most common flower colour is white, but there are Datura varieties that produce red, yellow and lavender flowers.

  1. 1

    Obtain Datura seeds. You can purchase Datura seeds from a reputable nursery. The nursery will probably call the plants angel trumpets. If you have a Datura plant, gather the spiny seedpods that develop at the end of the growing season and remove the seeds.

  2. 2

    Fill the planting flat with potting soil. Moisten the soil, but make sure it is still loose. Keep the soil at the same moisture level until the seeds sprout.

  3. 3

    Plant the Datura seeds in the planting flat just under the surface, about an eighth of an inch deep. Pat the soil lightly with the palm of your hand after planting the seeds.

  4. 4

    Place the flat in a warm spot until the seeds germinate. They will germinate in two to four weeks. Once the seedlings sprout, place them in a location with natural light or direct sun. They will do best over the winter if they are not over watered.

  5. 5

    Transplant the young plants outside when there is no danger of a frost. Choose a sunny location with soil that drains well. Carefully separate each plant to minimise root damage. Each plant can grow up to 6 feet wide, so leave about 4 to 6 feet between each plant if you transplant them to a planting bed. If you transplant them to a pot, one plant will fill a large pot as it matures.

  6. 6

    Gather the seeds from the new plants at the end of the growing season if you want to plant more plants for yourself or share them with friends. If you don't gather the seedpods, the seeds that fall will often sprout in the spring. If you want to preserve these seedlings, transplant them to a pot or location where they will have plenty of room to grow.

Tips and warnings

  • Datura seeds can be planted outside in the spring, but you risk damage from frost or pests.
  • Datura can be grown indoors as a houseplant, but should be kept cool and dry during the winter months.
  • You can propagate Datura plants by cutting off and replanting a portion of the root.
  • Datura plants are toxic. They should not be planted in areas accessible to children.
