|Pilea peperomioides and offspring|
Pilea peperomioides (/ /), the Chinese money plant or missionary plant, is a species of flowering plant in the nettle family Urticaceae, native to Yunnan and Sichuan provinces in southern China.
In 1945, the species was found by Norwegian missionary Agnar Espegren in Yunnan Province when he was fleeing from Hunan Province. Espegren took cuttings with him back to Norway, by way of India, in 1946 and from there it was spread throughout Scandinavia.
Pilea peperomioides is an example of a plant that has been spread amongst amateur gardeners via cuttings, without being well-known to western botanists. They did not know its true classification until the 1980s. The first known published image appeared in the Kew magazine in 1984.
Pilea peperomioides is an erect, evergreen perennial plant, with shiny, dark green, circular leaves up to 10 cm (4 in) in diameter on long petioles. The leaves are described as peltate, i.e. they are circular with the petiole attached near the centre. The plant is completely hairless. It grows to around 30 cm (12 in) tall and wide in the wild, sometimes more when grown indoors. The stem is greenish to dark brown, usually unbranched and upright, and lignified at the base when mature. In poor growing conditions, the plants lose their leaves in the lower part of the stem and thereby assume a distinctive habit. The flowers are inconspicuous.
The plant has a superficial resemblance to Umbilicus rupestris but is not related.
This species occurs only in China: in the southwest of Sichuan province and the west of Yunnan province. It grows on shady, damp rocks in forests at altitudes from 1500 to 3000m. It is very rare and possibly endangered in its native habitat. However, it is kept in China and worldwide as an ornamental plant.
With a minimum temperature of 10 °C (50 °F), in temperate regions, P. peperomioides is cultivated as a houseplant. P. peperomioides is propagated from plantlets that sprout on the trunk of the parent plant (these are called offshoots) or from underground shoots (called rhizomes). It forms fast-growing foothills, which are often passed on as a lucky plant ("lucky thaler") or friendship plant. Since constant temperatures and high humidity have a positive effect on plant growth, this plant species is suitable for planting terrariums.
Although the plant is endangered in its native habitat, it is a popular houseplant -- it is among the most popular houseplants today. It’s in high demand because it’s slim, easy to grow and tolerate of dry environments. But it’s not a new fad and has been further popularized by Instagram and TikTok trends.
Caring for a Pilea isn’t difficult. The plant can take a few days of dry soil between watering. Too much water can cause the leaves to drop. A week of neglect won’t kill it, either. It will retract into its pot and wait until you notice it again.
