Pilea is a genus consisting of about 600 species of frost tender, tropical foliage plants
that includes both upright bushy types and trailing varieties.
Several smaller species are commonly cultivated as house plants because they are so easy to grow and care for.

These inexpensive little plants are excellent for growing in dish gardens
and are great starter plants for young or inexperienced growers.
Their foliage varies considerably, ranging from 3" strongly textured,
lance shaped leaves to tiny heart shaped, moss-like foliage.
Pileas occasionally bloom, but their pink or cream colored flowers are very tiny and often go unnoticed.

Growing Requirements for Pilea Plants

Willy the Garden Gnome Pileas are only hardy in USDA zones 10-12. They all have the same basic growing requirements.
Pilea plants should be grown in bright, indirect light, but never in full sun.
They will thrive under fluorescent 'grow lights'.

Always keep your Pilea and any other house plants away from heating vents and out of drafts.
Pilea plants grow best in warm daytime temperatures of 75°-80° with 10 degrees cooler at night.
Pileas need about 50% humidity in order to thrive, so they should be kept on a tray filled with moistened pebbles or misted regularly, or they can be grown in a terrarium.

Keep the soil slightly moist while your Pilea is actively growing,
but allow the top inch of soil to dry between waterings when growth slows in the winter.
Feed monthly in the spring and summer using a half-strength solution
of a liquid house plant type fertilizer with a N-P-K ratio of 3-1-2..
Watch closely for spider mites!

Pruning and Potting Pilea Plants

Pinch the tips of new growth on branching forms of Pilea to help keep the plant compact.
Even with diligent pinching and regular clipping, Pileas tend to become leggy and
unattractive because their lower leaves naturally drop with age.
Luckily, Pilea cuttings root easily, so you can replace your old specimens with fresh new plants every year or two if you'd like.

Pileas grow best in smaller, 4" pots or planters where their roots will be somewhat restricted.They should be planted in a peat moss based commercial potting mix with leaf mold and perlite added, or a mix specifically for African Violets.

Propagating Pileas with Stem Cuttings

Pileas are very easy to propagate with stem tip cuttings.
Take tip cuttings in the spring. Strike 2 or 3 cuttings in a 3" pot
filled with moistened potting mix. Place the pot in a propagating case or in a sealed plastic bag to hold in humidity.
If kept at 75° your new plants will be rooted and growing in 3-5 weeks.
An Aluminum Plant, Pilea cadierei

Aluminum Plant
Pilea cadierei

Aluminum Plants are native to Vietnam. They are fast growing, easy to care for plants that branch freely and grow 12"-18" tall. These plants have 3", deep green, lance shaped leaves arranged in pairs along their upright, succulent stems. The fleshy leaves are accented with bold bands of metallic silver. Good plants for growing in dish gardens or as specimen plants.

Friendship Plant
Pilea involucrata

Friendship Plants are native to Central and South America, where they are known as Panamiga plants. They are creeping plants that form dense, 8"-12" tall mounds of deeply textured, oval, 2½" leaves. The foliage color varies, but the most common variety has dark, reddish brown leaves gilded with silver or copper. The leaves have purplish undersides.

A Moon Valley Pilea, Pilea involucrata 'Moon Valley'

Moon Valley
Pilea 'Moon Valley'

Moon Valley is cool little cultivar of the Friendship Plant, Pilea involucrata. It is a bushy, fast growing upright plant that grows to about 12" tall. Their greatest feature is their saw toothed edged, chartreuse leaves with deep texturing like the craters and valleys on the moon. (sometimes you have to use your imagination..) Excellent for terrariums or dish gardens.

Artillery Plant
Pilea microphylla

The Artillery Plant is a short lived perennial from Central America that forms
an umbrella like canopy of tiny, bright green leaves on fleshy, 6"-12" stems.
The name Artillery Plant comes from the way that its seed pods forcibly eject their
pollen or seeds when the frond is touched. An excellent plant for terrarium environments.

A Miniature Peperomia, Pilea depressa

Miniature Peperomia
Pilea depressa

Miniature Peperomias are low growing, creeping plants with pairs of tiny, opposing round leaves on rigid stems that readily root at each node that contacts the soil.
Unlike other Pileas, this ground cover plant prefers lower humidity and drier soil.
A nice, but fairly plain plant for hanging baskets or to cover the soil in large planters.
