Japanese Morning Glory 'Gray Lady'

That's a great note from Ron_Con.
I also grew mine for the first time this year. I started it indoors in Apr. and earthed it late...Read More June. It grew well and hearty. It began to bloom the first of Aug. The first bloom was mauve! That went on for a week or 2 and then the whitish gray game along and blooms about 12 or 14 blooms daily. At least twice a week, the little mauve one appears.

Very pretty pastel grey with a hint of mauve undertone. From certain angles it appears to be a shimmery white but will change as you move...Read More angles...This is a very intresting flower of about 4 inches in diam. but this is also the first year for me to grow it and these are my first flowers so I may ammend my comments later.
