I have a couple of C. amethystoglossa in bloom. This is the better of the two in color and shape. The plant was obtained from H&R Nurseries of Waimanalo. It is a cross of C. amethystoglossa 'H&R Supreme' x C. amethystoglossa 'Hihimanu'. The slightly cupped flowers have a natural spread of 3-1/4 inches. The front growth is 18 inches tall (measured to the base of the flower stem).
