Peperomia - the radiator plant - is a genus of the Piperaceae family with more than 1500 species the majority being native to tropical America. Most of them are compact, small perennial epiphytes growing on rotten wood. Though varying considerably in appearance they generally have thick, stout stems and fleshy leaves, with flowers in yellow to brown conical spikes.
They are small compact perennials usually not exceeding 12 inches (30 cm) in height, grown for their ornamental foliage as houseplants, except for the succulent species.

Identify my radiator plant
The radiator plant is a perennial with evergreent fleshy leaves, alternate or verticillate, elliptical or cordiform, on long petioles. The flowers are for the most part discrete and white with erect ears.
Plant my radiator plant
You can plant your radiator plant, in pots, in bottles or other small containers, in a fibrous mix of compost or heathsoil and pottinng soil.
The principle is that the mixture must be draining and rather neutral or acid, because the radiator plant "drinks" rather by its leaves.
Water my radiator plant
Peperomia does not like excess moisture, water once a week in season, but spray foliage often with non-calcareous water.
Fertilize my radiator plant
In summer, add liquid fertilizer for green plants every 2 weeks. Stop all fertilizer treatments at the end of summer.
Repot my radiator plant
Every 3 or 4 years, at the end of winter, transplant your peperomia carefully to a slightly larger pot than it's current, adding a mixture of heather earth, topsoil and garden soil.
Check on my radiator plant
Red spiders enjoy the dryness of the air.
Increase the humidity if you notice a transparency of the leaves. On the other hand, if you notice leaf swelling, the ambient humidity is too high, reduce the intakes - do the same in case of roots rotting.
Prune my radiator plant
Vigilant deadheading once or twice a week will prolong the blooming period !
