Peperomia rotundifolia is a newly released Peperomia that produces masses of 1cm jade-green leaves on long runners.
It likes moist soil but can be sensitive to overwatering. I find that it's best watered from the base of the plant. Bright, indirect light will help to keep it happy.
It does like to be quite pot bound so be careful not to over pot - always only go up one pot size when potting up. Potting up is best done in spring. It can be fertilised in the warmer months with a half strength dose of liquid plant food.
