Thinned out due to drying out too much - 50% off shelf - not as pictured - The Heart fern (also known as heart-leaf fern or Hemionitis arifolia), is a petite fern famous for its adorable leaves, springy stems, and heart-shaped leaves. This plant can be grown in a pot, or in a terrarium. Heart ferns prefer bright, indirect light, although they are somewhat low-light tolerant.
