How to Plant Angel Trumpet Seeds


Angel trumpet, known botanically as Brugmansia, is a small, tropical flowering tree with an upright growth habit and pendulous trumpet-shaped flowers in the spring and summer. According to the University of Washington Botanic Gardens website, Brugmansia can be easily be propagated from fresh seed and will germinate within 20 days and produce a mature flowering plant within nine months.

Step 1

Plant your Angel trumpet seeds immediately when you receive them as fresh seeds germinate more readily.

Step 2

Prepare a seed flat or nursery pot with good drainage and fill with fresh, sterile potting mix to within an inch of the lip.

Step 3

Nestle the seeds into the surface of the soil covering with just a one-fifth inch of soil over the seed. Allow 3 to 5 inches between seeds when planting more than one per pot.

Step 4

Water the seed and surrounding soil until all of the soil in the pot is wet and the excess water drains through the bottom of the pot. Replace the soil over the seed if it gets displaced with watering. Keep the soil wet at all times.

Step 5

Cover the nursery pot or seed flat with a clear glass plate or a sheet of clear, plastic film to create a humid, greenhouse effect.

Step 6

Keep the pots in location with bright indirect light and ambient temperatures between 64 and 79 degrees Fahrenheit.

Step 7

Transplant the seedling into a larger pot or into the ground once it germinates or outgrows the current container.
