Pholidota imbricata (Necklace Orchid)
Few orchids tell a story as vividly as Pholidota imbricata. Widely known as the Necklace Orchid or Rattlesnake Orchid, this species produces crowded clusters of pseudobulbs, each carrying a single pleated, leathery leaf and a wiry flowering spike lined with up to sixty small, fragrant, cream to greenish-white cup-shaped blooms arranged in two neat ranks — the effect is exactly what the common name promises: a delicate strand of blossoms, cascading like beads on a chain.
The genus Pholidota takes its name from the Greek for “scaly,” a nod to the overlapping bracts along its flower spikes — a detail echoed in the species name imbricata, meaning “overlapping.” Native across a wide range from South China and India through Southeast Asia to Australia, this orchid grows naturally as an epiphyte or lithophyte, at home on tree bark or moss-covered stone alike — making it a resilient, forgiving addition to any collection.
