lily of the valley has something. the plant is well known to everyone. Especially in the perfume industry, the plant (its flower scent) is frequently used. This variegated lily of the valley is slightly different. It used to be sold as Convillaria liniette (which I actually think is a nicer name), because of its continuous yellow stripes in the leaf. This variety also flowers well. So this gave rise to growing and marketing it sparingly.
