Forgiving and beginner-friendly.
Watermelon peperomia earns its name from the silver-and-green striped leaves that really do look like watermelon rind. It is compact, pet-safe, and easy — it stores water in its leaves, so it forgives a missed watering more than it forgives a soggy pot.
About Watermelon Peperomia
Watermelon peperomia (Peperomia argyreia) takes its name from the rounded leaves striped in silver and green, which really do echo a watermelon rind. It comes from South America. It is compact, easy, and pet-safe, and it stores water in its thick leaves, so for a renter it is about as low-maintenance as a decorative plant gets in a small 2-litre pot.
Because it holds water in its foliage, it forgives a missed watering far more readily than a soggy pot. Let the top of the soil dry between waterings, and keep it in bright indirect light to hold the crisp leaf stripes. It likes to be a little snug, so there is no rush to pot it on. It stays small, mounding to around 0.2 to 0.3 metres.
What it’s like to grow
Watermelon peperomia is easy and forgiving, a good plant for a beginner or a forgetful waterer. Its main hazard is overwatering, which brings mushy stems and dropped leaves. Faded markings and leggy growth mean it wants more light. Keep it bright-ish and on the dry side and it looks after itself. It is non-toxic to cats and dogs, so the pot is safe around pets.
What to expect
It’s forgiving, so it’s a good one to learn on. No sunny window? It also does fine under a clip-on grow light.
