Phalaenopsis
Phalaenopsis · (Phalaenopsis spp.)
Orchid family (Orchidaceae)
Description
With its broad, leathery leaves and long-lasting, butterfly-shaped blooms in white, pink or purple, Phalaenopsis is among the most popular houseplants worldwide and, given good care, flowers nearly year-round; botanically it belongs to the orchid family. The plant contains typical orchid constituents such as flavonoids (kaempferol and quercetin glycosides), mucilage-forming glucomannan polysaccharides, phenolic acids, dendrobine-type alkaloids and minerals including calcium, magnesium and potassium. It is grown purely as an ornamental: its leaves contribute to indoor air quality, and its flowers are traditionally associated with wellbeing and mood, with orchids also carrying ethnobotanical significance in some Asian traditions. According to the ASPCA, Phalaenopsis is classified as non-toxic to dogs, cats and humans, making it a safe choice for households with children and pets. The only caution: commercially sold plants may carry pesticide residue, so leaves should not be eaten.
Phalaenopsis orchids use CAM photosynthesis (Crassulacean Acid Metabolism): daytime stomata remain closed, while at night they open for CO₂ uptake and release oxygen. This makes them one of the rare houseplants that produce O₂ at night.
As a flowering houseplant with long inflorescences, Phalaenopsis demonstrably improves wellbeing in interiors. In many Asian cultures, it is a symbol of fertility, elegance, and good fortune.
According to ASPCA, Phalaenopsis is not toxic to dogs and cats. The moth orchid is thus one of the safest flowering houseplants for households with pets and children.
Ethnobotanically, related Dendrobium orchids (Orchidaceae) were used in Traditional Chinese Medicine (TCM) — e.g., Dendrobium nobile as a yin tonic. For Phalaenopsis itself, a documented western or TCM medicinal use is barely substantiated.
According to ASPCA, not toxic to dogs and cats. Also classified as non-toxic for humans. Pesticide residues on commercial plants possible — do not consume leaves. ASPCA classification (accessed 2026-08-10): non-toxic to dogs and cats.
As a houseplant, no known toxicity; be aware of pesticides on commercial plants.
As a houseplant, no known toxicity.
Considered a safe houseplant for families with children (ASPCA category: non-toxic).
Harvested part: whole plant (decorative)
- Time of day:
- Morning (flowers at full opening; harvest for decorative purposes)
- Drying:
- Use fresh; silica gel drying possible for craft projects.
- Time of day:
- When repotting in spring/summer — do not cut aerial roots
- Alkaloide (Dendrobine-Typ, spp.-spezifisch)AlkaloidWhole plant
Orchidaceae-typical alkaloids; only in traces in Phalaenopsis, little studied phytochemically. Better characterized in related Dendrobium species.
- Flavonoide (Kaempferol, Quercetin-Glykoside)FlavonoidLeaf
Antioxidant flavonoid glycosides, typical for Orchidaceae; detected in leaves and flowers.
- Polysaccharide (Glucomannan-Typ)PolysaccharideRoot
Mucilaginous polysaccharides in the aerial roots; support water uptake and moisture release.
- Phenolcarbonsäuren (Hydroxyzimtsäuren)Phenolic acidAerial parts
Secondary phenols in various orchid tissues; role in pathogen defense.
- Mineralien (Calcium, Magnesium, Kalium)MineralWhole plant
Micronutrients essential for CAM metabolism and flower formation.

Tips:
- Keep in transparent pot — roots photosynthesise too.
- Dunk in water for 5 min weekly instead of daily watering.
- CAM plant: produces O₂ at night, ideal for bedroom.
- After flowering: cut stem above 2nd node — re-flowering possible.
