Can you give me specific directions on how to germinate Brugmansia seed and care for the seedlings. Also, at what age or size do these plants flower?
The following information is quoted from the book Brugmansia and Datura: Angels' Trumpets and Thorn Apples (by Ulrike and Hans-Geog Preissel, 2002, p. 74):
The fresh seed should be sown as early as possible, at temperatures between 64--79 F. Cover the seed with approximately 1/5 (.20) inch of humus, which must be kept wet.
The seed is relatively large and is pressed lightly into the hummus to ensure contact with the moist planting mix. Initially cover the seed box with a glass plate to provide optimal humidity. At temperatures around 68 F, the various species of Brugmansia germinate very differently. As a rule, germination takes between 10 and 20 days. The young seedlings can then be planted out directly into small containers.Young plants that are grown from seed go through an immature phase, easily recognized by the change in leaf shape. The plants do not reach flowering maturity until the end of this immature phase. The length of time before the first flowering varies with the species. On average, most Brugmansia flower for the first time when the plant is between 2.5--5 feet in size. If they are well cultivated, then they will usually reach this size in six to nine months.
Plants grown from seed can look very different. They differ not only in leaf shape and size, flower shape, color and size, but also in other traits, such as susceptibility to diseases or willingness to flower. The possibilities are almost endless and many interesting and valuable discoveries are undoubtedly waiting to be made....
