This particular torenia is a welcome addition to the shade garden, providing a beautiful amethyst color that isn't that common in shade-blooming annual flowers. 'Summer Wave Large Amethyst' torenia is a natural for hanging baskets and container planters, cascading over the edges with nicely branching foliage. The snapdragon-like blooms have wishbone-shaped stamens, so plant this annual where you can see it up close.
