Brugmansia can be grown from seed but you are going to need artificial heat and light, and patience, to get them going.
First soak the seeds in warm water for twenty four hours.
The seeds should then be placed on a seedling compost mixed with perlite. Do not cover the seeds, just lay them on the surface and gently press them on to the compost. They need heat so put the seed tray on a grow mat at about 15C.
Keep the seeds moist with a fine water spray. The seeds like high humidity so try to house them in an enclosed propagator or enclosed plastic container.
Brugmansia seeds germinate via light and will not germinate without artificial light. The seeds need about 20 hours light per day to get going.
They will take up to four weeks to germinate
