I planted three small plugs in my garden in April 2008. They didn't show much growth until the weather became consistantly warm. Princess is a beautiful maroon color. The leaves are wider than purple fountain grass although the color is similar. They resemble New Zealand flax in form.

Its only mid July 2008, but I am really pleased with their color, size, and form. They are close to 2 feet tall now, but I am expecting an additional foot of growth before the year is through.
