Just thought I give you an update on my cumingiana. It does very well in our summer heat here and and is budding and flowering on several shoots.
It is very fragrant, but - isn't it supposed to smell of Citrus and Coconut? The topnote is surely very strongly Citrus. About the coconut? I haven't detected that at all, it smells a little like Pledge ( if one could perhaps compare it to grapefruit scented pledge) or other floor wax. It isn't unpleasant, just strange.
Has anybody else noticed that?
