A quick reference to orchid structures—labellum, spikes, roots—to help confirm genus at home.
Key Traits
Orchids (family Orchidaceae) usually display bilateral symmetry; a specialized petal (the labellum or lip) guides pollinators. Many have thick aerial roots and may grow on trees (epiphytes).
Popular Genera at Home
- Phalaenopsis: flat, moth-like blooms; arching spikes; broad leaves at the base.
- Dendrobium: blooms along canes; some species are deciduous; diverse flower shapes.
- Oncidium: many small, ruffled flowers; dancing-lady look.
Photo Checklist
- Whole plant (leaves, roots, spikes).
- Flower front, side, and close-up of the lip.
- Any pseudobulbs or canes.
Care Notes
Bright, indirect light; thorough watering followed by drying; airy potting (bark, sphagnum); avoid standing water in crowns.
