It’s easy to see where the heart leaf fern or heart fern (Hemionitis arifolia) gets its name. This charming plant’s most distinctive feature is its glossy, dark green, heart-shaped leaves, which can add a touch of elegance to any indoor garden.
Interestingly, many heart ferns feature two shapes of leaves. They are dimorphic, meaning some of the leaves are sterile and some are fertile. Sterile fronds tend to be heart shaped, while fertile fronds look more like an arrowhead and are on a thicker stalk.
Because of its compact size (it typically only grows between 6 and 8 inches tall), this plant packs a lot of style and in small space. As a plant native to Southeast Asia, the Heart Leaf Fern likes high humidity and warmth and recreating those conditions will keep your plant happy.
