Moth Orchid

Brief Description

An epiphytic orchid with broad, flat, fleshy green leaves and long, arching flower spikes that can produce multiple blooms.

Care Instructions

Provide bright, indirect light and plant in an airy orchid bark mix. Water once a week or when the roots look silvery, ensuring excellent drainage. Fertilize monthly with orchid-specific fertilizer.

Medicinal Value

We do not currently provide medicinal value for plant identifications.

Sunlight

Bright indirect light like an east-facing window; avoid direct afternoon sun which can scorch leaves. 10-12 hours of light is ideal.

Watering

Water approximately once per week. Allow the medium to almost dry out; roots should turn from green to silvery-gray before watering again. Avoid leaving water in the leaf crown.

Soil

Requires high drainage and aeration; use a dedicated orchid bark mix or sphagnum moss. pH 5.5 to 6.5.

Hardiness Zone

USDA zones 10-12; generally kept as an indoor houseplant between 60-85°F (15-29°C).

Growth Habit

Monopodial perennial; grows from a single stem with opposite leaves. Indoors, it typically reaches 1-2 feet in height including the flower spike.

Bloom Season

Can bloom at any time of year, with flowers lasting 2-4 months. To trigger re-blooming, a slight drop in nighttime temperature is often required.

Toxicity

Generally considered non-toxic to humans, dogs, and cats according to the ASPCA.

Propagation

Most commonly through 'keikis' (baby plantlets that grow on the flower spike) or by laboratory tissue culture; seed propagation is extremely difficult for hobbyists.

Common Pests & Issues

Root rot due to overwatering, mealybugs, scale, and crown rot. Bud blast (dropping buds) can occur due to sudden temperature or humidity changes.

Similar Species

Vanda orchids (which have thinner leaves and different root structures) and Cattleya orchids (which have pseudobulbs).

Interesting Facts

Phalaenopsis means 'moth-like,' named because the flowers were thought to resemble moths in flight. They are one of the most popular houseplants in the world because their blooms last exceptionally long.
