Known for being a prolific bloomer, the Pink Mayla Winter Hardy Lily has immense double fuchsia flowers, with some slight green foliage. It also features plum colored leaves, and it is a prudent selection for medium to large pools.
Other than zones 9 and 10, it does need full sun, although it often does better with a little shade and cooler temperatures. That is especially true during the dog days of summer. Its purple-red tint will surely leave an impression on people checking out your pond.
