Plant Description

Aluminum Plant

The Aluminum Plant, scientifically known as Pilea cadierei, belongs to the Urticaceae family. It is native to Vietnam and China, where it thrives in the tropical and subtropical climates. This perennial herbaceous plant is known for its stunning foliage, featuring dark green leaves adorned with intricate silvery patterns that resemble aluminum. The leaves are oval-shaped, measuring about 2-4 inches in length, and are arranged in an opposite pattern along the stems.

The Aluminum Plant is a relatively compact houseplant, typically growing between 12-18 inches in height. In its natural habitat, it can be found growing in shaded areas, often along the base of trees or shrubs. Although the Aluminum Plant is grown primarily for its ornamental foliage, it does produce small, inconspicuous flowers in the wild. However, it rarely flowers when grown indoors as a houseplant.


The Aluminum Plant was first discovered in the early 20th century by French botanist Henri François Pittier, who collected specimens of the plant during his expeditions in Vietnam. He named the plant after the French botanist and priest, Michel Cadière, who had conducted extensive botanical work in Vietnam. Pilea cadierei quickly gained popularity as an ornamental plant, with its unique foliage making it a highly sought-after specimen for collectors and houseplant enthusiasts alike.

Natural Habitat:

In its native range, the Aluminum Plant is found in the moist, humid environments of Vietnam and China, where it grows as an understory plant in subtropical and tropical forests. It is well-adapted to growing in shaded, humid conditions and is often found growing alongside other moisture-loving plants, such as ferns and orchids. In these environments, the Aluminum Plant is an important component of the forest understory, helping to maintain soil stability and supporting the rich biodiversity of the region.

Growth Patterns:

The Aluminum Plant is a relatively fast-growing houseplant, with new leaves emerging from the stem tips throughout the growing season. It has a bushy, spreading growth habit and can become leggy if not properly pruned.

To maintain a compact, attractive shape, it is recommended to pinch back the stem tips regularly, encouraging the plant to produce side shoots and become more bushy. This will also help prevent the plant from becoming top-heavy and encourage a more balanced growth pattern.

Identification of Plant

Aluminum Plant (1)

The Aluminum Plant is easily identified by its striking foliage, which is the primary reason it is grown as a houseplant. The leaves are dark green, oval-shaped, and measure between 2-4 inches in length. They have a unique silvery, metallic pattern that creates a stunning visual effect. This shimmering appearance is the result of specialized cells called iridoplasts, which reflect and scatter light, giving the leaves their characteristic aluminum-like sheen. The plant itself typically grows between 12-18 inches in height, with a bushy, spreading growth habit.

Although it rarely flowers when grown indoors, the Aluminum Plant does produce small, inconspicuous flowers in its natural habitat. These flowers are white or green and are relatively insignificant compared to the plant’s dramatic foliage. When grown outdoors, the Aluminum Plant may also develop a woody stem base, adding to its overall attractiveness.

Types and Varieties

While Pilea cadierei is the most well-known species within the Aluminum Plant group, several other Pilea species with similar characteristics are also grown as houseplants. Some of these varieties include:

  • Pilea cadierei ‘Minima’: A compact, dwarf variety of the Aluminum Plant, ‘Minima’ grows only about 6-8 inches tall. It has smaller leaves with the same characteristic silver patterning but is more suited to small spaces or terrariums.
  • Pilea glauca ‘Aquamarine’: This variety is known for its small, rounded, blue-gray leaves that form a dense, mat-like carpet. ‘Aquamarine’ is perfect for hanging baskets or as a ground cover in terrariums, as it has a trailing growth habit.
  • Pilea involucrata ‘Moon Valley’: With its heavily textured, deep green leaves and contrasting red stems, ‘Moon Valley’ is a visually striking variety. The leaves have a quilted appearance, and their deep grooves catch the light, creating a unique effect.
  • Pilea nummulariifolia ‘Creeping Charlie’: This fast-growing, trailing variety has small, rounded, green leaves with a slightly fuzzy texture. It is an excellent choice for hanging baskets, where its long trailing stems can cascade down for a stunning display.

Facts about the plant

  • The Aluminum Plant’s unique metallic foliage is due to specialized cells called iridoplasts that reflect and scatter light, giving the leaves their characteristic shimmering appearance.
  • Pilea cadierei is named after the French botanist and priest, Michel Cadière, who conducted extensive botanical work in Vietnam.
  • The Aluminum Plant is non-toxic to cats and dogs, making it a pet-friendly houseplant option.
  • In its natural habitat, the Aluminum Plant is an important component of the forest understory, helping to maintain soil stability and supporting the rich biodiversity of the region.
  • Despite being a tropical plant, the Aluminum Plant can be grown as an annual in temperate climates, adding a touch of the exotic to outdoor containers and borders during the warmer months.

Tips to Grow Aluminum Plant

  • Light: Provide bright, indirect light for the Aluminum Plant, as direct sunlight may scorch the leaves. A location near an east or west-facing window is ideal.
  • Water: Keep the soil consistently moist, but not soggy. Allow the top inch of soil to dry out slightly between waterings to prevent root rot.
  • Soil: Use a well-draining, peat-based potting mix to provide the appropriate balance of moisture retention and drainage.
  • Humidity: The Aluminum Plant thrives in a humid environment. To maintain adequate humidity, place the plant on a tray filled with pebbles and water, mist the leaves regularly, or use a humidifier.
  • Fertilization: Feed the plant with a balanced, water-soluble fertilizer every 4-6 weeks during the growing season (spring and summer). Reduce fertilization to once every 8 weeks during the fall and winter months.
  • Pruning: Pinch back the stem tips regularly to encourage bushy growth and prevent the plant from becoming leggy.

Major Problems

While the Aluminum Plant is generally easy to care for, it can encounter a few common issues. Some of the major problems include:

  • Overwatering: Excessive moisture in the soil can lead to root rot, a common issue for Aluminum Plants. To avoid this problem, allow the top inch of soil to dry out between waterings and ensure proper drainage.
  • Pests: The Aluminum Plant may be susceptible to common houseplant pests, such as spider mites, aphids, and mealybugs. Inspect the plant regularly for signs of infestation, and treat promptly with insecticidal soap or neem oil.
  • Legginess: Insufficient light or inadequate pruning can cause the Aluminum Plant to become leggy and unattractive. To prevent this, provide bright, indirect light, and pinch back the stem tips to encourage bushy growth.

Frequently Asked Questions

Can the Aluminum Plant be propagated easily?

Yes, the Aluminum Plant can be propagated through stem cuttings. Take a 4-6 inch cutting, remove the lower leaves, and place it in a pot with moist, well-draining soil. Cover the cutting with a plastic bag to maintain humidity, and roots should begin to form within a few weeks.

How often should I repot my Aluminum Plant?

The Aluminum Plant should be repotted every 1-2 years, or when it becomes root-bound. Choose a pot that is 1-2 inches larger in diameter and use a well-draining, peat-based potting mix.

Why is my Aluminum Plant losing its silver patterns?

A lack of sufficient light can cause the Aluminum Plant to lose its characteristic silver patterns. Ensure the plant is receiving bright, indirect light to maintain its vibrant foliage.

How can I encourage my Aluminum Plant to produce more side shoots?

Regularly pinching back the stem tips will encourage the plant to produce side shoots and maintain a bushy, compact growth habit.
