In cooler weather, Red Metamorph's flowers are a deep burgundy, but when the weather warms, watch as splashes of yellow appear on the petals! Then when cooler weather comes back around, the blooms change back to solid burgundy. Beautiful as a garden hedge, this French marigold is stout and dense at about 2'-3' tall. French marigolds are edible, but with a very strong flavor similar to its pungent scent. Prolific bloomer attracts beneficial insects.
