Gardeners' Notes:

The original 'Plum Frost' was a beautiful purple bloom with white frosty patterns at the edge. It was introduced by EmmaGrace (one of many :) and promptly spread to other ipomaniacs (MG lovers) who grew the seed and got a number of beautiful variations such as OhioBreezy's, with much less "frosting" of the blooms and a deeper purple tint.

Mine grew out to be simple, solid pink/purple blooms with a white eye.
