Emerald Gem Homalomena (sometimes known as Queen of Hearts plant) is an upright plant with dark green, waxy, spade-shaped leaves.  Although an Emerald Gem plant is a relative of the easy-care philodendron, it is a bit more finicky and requires more attention. Homalomena will produce flower spathes, although they rarely open and are inconspicuous. Removing the spathes as they form will keep Emerald Gem producing more foliage. At maturity, this plant is about 18 to 30" tall and wide so it's great for small areas.
