With its ornate flowers, the angel's trumpet is undoubtedly one of the most decorative ornamental plants. No wonder it is coveted and propagation tempting. Propagation by cuttings is the standard method here - but you can also use the seeds.
Growing from seed is challenging but possible
What speaks for seed propagation
If you want to propagate an angel's trumpet, you can do it quite easily - because the beautiful plant from the Andes can be multiplied very easily using the conventional cuttings method. This does not require much effort and you can count on a high success rate.
Of course it is also possible to grow an angel's trumpet from seeds. However, this is a bit more complicated. What speaks for it, however, is that other flower colors can appear in the plant germinated from seed. With cuttings, on the other hand, the plant is simply “cloned”, so to speak. For those who like to experiment, seed cultivation can of course also simply be an attractive gardening challenge.

How to proceed with seed cultivation
Take only fully mature seeds
If you are collecting seeds from an angel's trumpet specimen yourself, make sure they are fully mature first. Only then are they viable. At this stage they are usually in early fall. An important note: Don't forget to work with gloves, as the seeds are one of the most poisonous parts of the angel's trumpet!
Dry over winter, sow in spring
The seeds must be dried over the winter. Because sowing can only take place in the spring, when the development of light is on the rise. Put the seeds in pots with potting soil, to which you add some slow-release fertilizer.
Uniform temperature and humidity
You should then place the growing pots (€16.68) in a bright place where a constant temperature of 20°C is guaranteed. A conservatory or a warm greenhouse is ideal.
The moisture supply must also be as even as possible. A proven method for creating a sheltered, continuously humid microclimate is to cover the pot with a foil bag. Underneath, the seed has more rest and is protected from drying out.
The seeds should germinate in about two to three weeks. When this is successful, you can remove the foil bag, but continue to keep the plant evenly moist. As it grows, you can gently and gradually acclimate it to more temperature and light changes.
