Datura is a lovely flower that can be grown in pots for the patio or in the ground as a stunning late summer bloom that is sure to attract attention. Also known as angel's trumpet, datura is not a commonly grown plant, mostly because eating any part of the plant can be deadly, so plant with caution, and keep the seeds in a safe place.
In some parts of the United States, datura has become naturalized as it reseeds itself under the right conditions. In cold climates, datura is grown as an annual.
Planting seeds at the correct time is imperative if you want to have the proper sized seedlings when it is time to plant them in the ground. Datura seeds need to be sown 6-8 weeks before the date of the last frost in spring. For instance, if your typical last frost is May 15, you should sow the seeds around March 15.
Soak the seeds overnight in a wet paper towel on a plate. This will greatly improve the germination rate.
Place 4 cups of the planting medium in the garbage bag and add 1 1/2 cups tepid water. Close the bag and knead the soil until all of the water is absorbed. Repeat as many times as you need for your planting flats/trays.
Put the moistened soil into the flat and fill to just below the top. Make sure to fill in the edges and corners.
Make rows with the pencil and carefully plant the seeds an inch or so apart. Cover the seeds with 1/4 inch of soil and gently firm the soil to make sure the seed has good contact with the soil.
Lay plastic wrap over the top of the flat--not to seal but just to help keep moisture in.
Place the flat on the grower's mat where it will not be disturbed and away from drafts.
Bottom-water to prevent soil from drying out.
Plants should germinate in approximately 2 weeks.
