A native to South America the Peperomia argyreia is a small plant grown for its attractive leaves. They grow up to 12 inches tall and the mini watermelon peperomia only grows up to 6 inches. Because of their small bushy rosette appearance they're best suited when grown outdoors as a ground cover or grouped together with other plants indoors.
Foliage: For the size of this plant as a whole the leaves are fairly large. These peltate leaves (stem attached centrally) are kind of oval in shape and display an outstanding mixture of green and silver stripes. The leaves have a fleshy feel to them that are attached to thin non-woody red stems.
Flowers: Non showy flowers can appear during summer on slim stalks (flower spikes) that are greenish in color. They are not even worth a mention if a grower is looking for attractiveness in flowers. They're all about foliage.
Care level and growing: These are very easy to grow and can make a good plant choice for the beginner. Keeping to the basics of care instructions will allow these plants to thrive. Most important is enough light, no overwatering and cold conditions.
I would display them close to other plants that have similar care needs to help them look more attractive, otherwise they can look a bit isolated because of how small they're. They can be placed in a planter and look great, but you will need to make sure other plants share the same care needs.
|Names:||Watermelon Peperomia (common). Peperomia argyreia [Syn. P. sandersii] -- (botanical/scientific).|
|Max Growth (approx):||6 - 12in tall.|
|Poisonous for pets:||Non-toxic to cats and dogs.|
|Temperature:||Prefers temperatures of 65-75ºF (18-24ºC), and no lower than 50ºF (10ºC).|
|Light:||A bright room with the plant placed in a shaded spot is ideal, without direct sunlight. In their natural habitat they reside undercover within forests with some sun and shade so we need to try and replicate this. Sitting back from a west, east or even south facing window is best.|
|Watering:||It's important not to water these plants too much or underwater them. Over-watering can cause rot and under-watering will make them wilt. To get watering just about right, allow the soil to dry to the touch at the top and then water thoroughly, but much less during winter.|
|Soil:||A peat based soil is best used that drains well. 2 parts peat and 1 part perlite is a good mix.|
|Re-Potting:||You will not need to re-pot one of these very often as they quite like to be pot bound. After about 3 years you may need to move to a slightly bigger pot, to be done during spring. You can replace the top soil once very spring.|
|Fertilizer:||During the spring while the plant is growing use a diluted liquid fertilizer once every 2 - 4 weeks until the end of summer.|
|Humidity:||Average indoor humidity should be fine. You can mist the leaves every now and again during summer months if the air becomes dry. Being around other indoor plants will improve humidity.|
|Propagation:||The most common and easiest way to propagate a peperomia of this type is by leaf cuttings. Remove leaves with petioles (stalks ) and use rooting hormone on the cut before planting in seedling and cutting compost. About 1 inch of stalk with a leaf should be fine and keep the soil moist and warm.|
