It reaches a bushy height of about four feet and is smothered with modest sized yellow flowers with brown centers by late summer. I tried germinating Datura at a temperature of 75 F and was surprised when they germinated in eleven days instead of cooking. As a test, I am trying some Brugmansia seeds with bottom heat. So far the first germinated in sixteen days. As usual, I have a number of annuals going.
Germination is swift with bottom heat.
After they pop up, I move them off the warmth of incubation to grow cold and strong under fluorescent lights in my basement. I use a fan to blow gently across them to keep them cool even from the modest heat given off by the fluorescents while the seedlings are very small and the lights are very close. The fan is a 110 volt clock motor with blades cut from aluminum flashing. Air speed is adjusted by changing the pitch of the soft aluminum blades. At the end of last month, the Watson Garden Center in Lafayette NY held its Spring festival to benefit Hospice.
