Key Largo's 6-8" flowers vary in color from browns to purples, depending on weather and care. But whatever the color, the flowers are always fascinating. With some pruning, the bush becomes well-branched and tall. The flower has great texture and petal strength, and the colors are the result of crossing Fifth Dimension and Joan Hingerton.
