Fun Facts
- 🌱 Dendrobium orchids are the second most commercially important orchid genus worldwide, surpassed only by Phalaenopsis. Purple Charm is one of the most popular hybrid colors in the orchid trade.
- 🌱 The name 'Dendrobium' comes from Greek words 'dendron' (tree) and 'bios' (life), meaning 'living on trees'—these orchids are epiphytes that naturally grow on tree branches in tropical rainforests rather than in soil.
- 🌱 Dendrobium Purple Charm flowers can last 4-8 weeks on the plant and 2-3 weeks in a cut flower vase, making them exceptional value for long-term enjoyment compared to most fresh flowers.
