Pilea libanensis aka Aluminium Plant

Taxonomy ID: 13461

Pilea libanensis is a small herbaceous plant in the family Urticaceae, formally described by Urban in 1930. It is endemic to Cuba, known only from a single mountain locality — Monte Libanon (also spelled Líbanon) in the Guantánamo province of the Oriente region — from which it takes its species epithet. Herbarium specimens from the early twentieth century document it growing in shaded places on steep rocky cliffs, suggesting it is a lithophytic or saxicolous herb adapted to sheltered, humid microhabitats. The species occurs within protected areas (Parnaso - Los Montes and Pinares de Montecristo) and is considered a Cuban endemic. Its conservation threat status is listed as Data Deficient in available biodiversity datasets.

Taxonomically, Pilea libanensis is accepted under the authorship of Urban (1930, Arkiv Bot. 23: A. No. 5, 28). Two heterotypic synonyms are recognized: Pilea pendula Griseb. (1866) and Adicea pendula (Griseb.) Kuntze (1891). The genus Pilea belongs to the order Rosales and comprises hundreds of species ranging from small creeping herbs to erect subshrubs, many of which are cultivated as houseplants.

No cultivated records, horticultural trials, or commercial availability data have been located for Pilea libanensis specifically. Care guidance for this species must be inferred from its known wild habitat (shaded, rocky, humid cliff faces in tropical Cuba) and from general Pilea genus culture. By analogy with well-studied congeners such as P. microphylla and P. involucrata, the species would be expected to prefer indirect or filtered light, consistently moist but well-drained substrate, warm temperatures, and moderate to high humidity.

More information about Aluminium Plant

How difficult is it to care for Aluminium Plant?

Pilea libanensis is not commonly cultivated and has no established care record, so difficulty is inferred from its wild habitat and genus. Most Pilea species are considered easy to moderate houseplants that adapt well to typical indoor conditions. The species' origin in shaded, humid, rocky cliff environments in tropical Cuba suggests it would tolerate a range of indoor conditions but may require attention to humidity and consistent watering.

How big does Aluminium Plant grow?

Moderate

No cultivated size data is available for Pilea libanensis. It is a small herb in the family Urticaceae; most small-leaved Pilea species in similar ecological niches (shaded, rocky habitats) remain compact, typically under 20–30 cm in height. The genus is not known for large stature. Growth rate in cultivation is unknown.

What temperature does Aluminium Plant prefer?

Pilea libanensis is native to tropical Cuba (Guantánamo province), where temperatures are warm year-round and rarely drop below 15 °C (59 °F). It is therefore expected to be frost-tender and suitable for warm indoor environments. Cuba broadly corresponds to USDA hardiness zones 11–13.

Does Aluminium Plant flower?

Flowers in the genus Pilea (Urticaceae) are typically tiny, inconspicuous, and produced in small clusters. Some species are monoecious (male and female flowers on the same plant) or dioecious. Specific flowering data for Pilea libanensis is not documented in available sources.

What varieties of Aluminium Plant exist?

No cultivars or horticultural varieties of Pilea libanensis are documented. The species itself is rare and known only from wild Cuban populations. Two botanical synonyms exist: Pilea pendula Griseb. and Adicea pendula (Griseb.) Kuntze, which are names applied to the same taxon in earlier literature.

Can Aluminium Plant be grown outdoors?

🇺🇸 USDA 11-12

Pilea libanensis is native to tropical Cuba and would only be suitable for outdoor cultivation in consistently warm, frost-free climates (broadly USDA zone 11+).

How to propagate Aluminium Plant?

No specific propagation data for Pilea libanensis is documented. Within the genus Pilea, most species are readily propagated by stem cuttings or division. Given the species' herbaceous habit, stem-tip cuttings rooted in a moist medium under high humidity would be the most likely approach consistent with genus-level practice.

What pests and diseases affect Pilea libanensis?

No species-specific pest or disease data is published. NC State Extension's profile for the closely related Pilea microphylla notes that root rot can develop if the soil is kept too wet, which is the most commonly reported husbandry problem across the genus.

How is Aluminium Plant pollinated?

The genus Pilea (Urticaceae) is generally wind-pollinated or insect-pollinated; many species explosively discharge pollen. No specific pollination data for Pilea libanensis is available in any accessed source.

Is Pilea libanensis edible?

Pilea libanensis has no documented food use in PFAF or other major edibility databases, and no record of edibility appears in POWO, GBIF, or World Flora Online. Within Urticaceae a few species (notably Urtica dioica) are eaten after cooking, but this does not extend to Pilea libanensis.

What are the medicinal uses of Pilea libanensis?

There is no documented medicinal use of Pilea libanensis in major ethnobotanical or phytochemistry references; POWO records no uses for this species. Some Urticaceae (e.g. Urtica dioica) have a long medicinal tradition, but that does not extend to Pilea libanensis.

What other uses does Pilea libanensis have?

POWO records no uses category for Pilea libanensis. Its only documented role is as a small ornamental houseplant in cultivation; no fiber, dye, or industrial use is reported.

What is the region of origin of Aluminium Plant

Aluminium Plant’s native range is Worldwide.

What are the water needs for Aluminium Plant

💧 Moist
Aluminium Plant should be watered regularly, allowing the soil to dry out between waterings.

What is the right soil for Aluminium Plant

Medium loamy
Aluminium Plant loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

What is the sunlight requirement for Aluminium Plant

To ensure optimal growth, the Aluminium Plant prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

What's the right humidity for Aluminium Plant

The Aluminium Plant does not necessitate supplementary humidity. Plants primarily absorb water through their roots, rather than their leaves. Hence, the most effective way to supply humidity to your plants is by watering the soil.

How to fertilize Aluminium Plant

The Aluminium Plant should be transferred to a new pot once it has increased in size two-fold, or on an annual basis, whichever occurs earlier. Replacing the soil with fresh potting soil containing all the necessary nutrients, is sufficient enough to support the growth of the plant, thus avoiding the need to use fertilizer. It's important to note that plants derive their energy from the sun and not fertilizer.

Is Aluminium Plant toxic to humans/pets?

Ploi does not possess verified information regarding the toxicity of this particular plant. In the event that you, a member of your family, or a pet ingests plant material with an unclear toxicity level, it is highly recommended to seek the advice of a medical professional.

What seasonal care does Aluminium Plant need?

During the cold period, it is common for Aluminium Plant to go dormant and their growth may slow down, so waterings should be spaced out more during this period.
