The Endless World of Orchids: 20,000 Species, 100,000+ Hybrids

Four Growth Habits

• Epiphytes: Cling to trees (most tropical orchids).
• Lithophytes: Grow on rocks.
• Saprophytes: Thrive in leaf litter.
• Terrestrials: Root in soil/sand.

Staggering Diversity

20,000+ wild species (many undiscovered) + 100,000+ man-made hybrids. Every continent except Antarctica. Hawaii = “Orchid Island.”

Debunking the “Difficult” Myth

• Many are tough: Phalaenopsis (moth orchid) thrives in average homes.
• Range: hot/humid to cool/dry. Match species to your conditions.
• Light needs vary—some want bright indirect, others tolerate lower light.

Common Pests & Fixes

• Spider mites, aphids, snails — wash off or insecticidal soap.
• Fungal/bacterial spots — improve airflow, reduce wetness, apply fungicide.
• Viruses — isolate, destroy if confirmed (no cure).

Choosing Your First (or Next)

Catalogs offer filters: flower size, color, fragrance, leaf type, bloom season, temperature tolerance. Start with a forgiving Phalaenopsis or Paphiopedilum.

Care Basics

• Water when media approaches dry; never let sit in water.
• Fertilize weakly, weekly (¼ strength balanced).
• Repot every 1–2 years in fresh bark/moss mix.
