String of hearts houseplants are exactly what they sound like: heart-shaped leaves dotted along trailing, string-like stems. If you already own one, or you know someone who does, it's really easy to learn how to propagate string of hearts and earn yourself some free plants.
Just as you can propagate pothos and other houseplants, you can multiply your collection of string of hearts plants through propagation. There are two key methods – in soil, or in water – and both, eventually, will grow a single cutting into a full-blown houseplant.
