Hi I bought a Two Daturas (the double frilly ones) Angel trumpet purple and white. They are in a 12" pot by a pond and have bloomed nicely but not grown in height. Now they have big balls I presume these are the seeds? What can I do with them? Shall I remove them and dry them? I most likely will keep them in an unheated greenhouse over the winter or MUST they come indoors? We also have an Yellow single Angel Trumpet bush, that I keep indoors from October and it keeps blooming well into autumn then I over winter it in the basement by an east window and prune it back. The main stem is now like 1 1/2" thick. Its about 1.5 m tall and quite wide in shape. Thank you.
