This variety has a lot of good attributes. It's a fast grower with nice dark green foliage and rippled foliage. I love the curly tips and the dark purple flowers.

Very dark green, wavy leaves with a rippled margin that can measure up to 10" long, ovate with a rounded base. Vigorous growing; upright, open, mounding habit about 17" ht x 24"w. Lush royal purple flowers in midsummer.

Parent: "seedling #10" x "seedling #10." 1998 Submitted by Mary Chastain. M. Chastain was noted for her dark leaved hostas, this one is reported to be possibly the darkest cultivar available.

The actual darkness of color is dependant on how much light it receives. The more shade, the darker the leaves. Some have recommended the addition of magnesium to the soil (one tablespoon of Epsom salts in a gallon of water every 2-4 weeks or so) to deepen the color.

This is one of my new hostas for 2005.
