Nephrolepis cordifolia ‘Duffii’ is a small variety of the popular Boston fern. Usually growing no larger than 1′ tall, Lemon Button Ferns feature tiny golden-green button-like leaflets on arching stems. These compact ferns prefer a shady location with filtered light that’s free from frost. In optimal soil and light conditions, they can multiply freely. They are an excellent choice for mass planting and use in woodland gardens as ground cover. They can also be used as indoor houseplants.
