Planting Seeds of Angel's Trumpet

I have some pods off an angel trumpet plant that are four or five years old. Are they still good to plant? How long are seeds good for?

Longevity of seeds varies with the type of seed and storage conditions. Angel trumpet, also known as Brugmansia (formerly Datura), seeds usually remain viable for 3 or 4 years when stored in a constantly cool location. So I think it is worth a try. Plus experimenting is half the fun of gardening. Remove the seed from the pods and in spring plant them in a warm moist seed starting or potting mix. Once the seeds sprout move them to a warm sunny location or under artificial lights. The transplants can be moved outdoors after the danger of frost has passed. Handle the seeds, seedpods and plants carefully as all parts are poisonous if eaten.
