I think I enjoy yellow leaf trait of Japanese Asagao as much as the variegated leaf, and am excited to see the leaves of some plants grown from seeds I received in a trade from Naomi. They are almost the same hue as is seen in Ipomoea batatas 'Margarita'. The yellow color can even be seen in the cotyledons.
This one, labeled as 'Budo Nezumi', should make a chocolate brown colored flower.
This one will make an intense red speckled patterned flower. I can't wait to see all of them!
