      Outstanding My favorite plant, I recommend to others all the time and explain the reasons why I like it so much.
    • Bought 4 of these plants and planted side-by-side. One of the 4 died even though they all received the same amount of light, water and nutrients. I expected more from a Proven Winner.

      Marginally Adequate Performed below expectations but may be willing to try again.
    • Very prone to rust.
