Info. on 'corkscrew' or' shell' vine , wisteria won't flower
I have some seedlings growing of a 'corkscrew' or 'shell' vine (vigna caracalla). Would anyone have any experience in growing this & have suggestions for me as to where to plant it .... shade, sun, wet, dry, etc.? I understand it will be an annual here in zone 7.
Also, I have a wisteria vine that I trained on the top rail of a chain link fence. It has never flowered & wonder what I can do to get it to produce flower buds. It is not overwatered or fertilized (I was told over doing this might be the cause)& I have another vine trained as a tree & it is just loaded with flowers every year!
