There are over 1000 types of dendrobium, also known as bamboo orchid.

They come in a range of sizes, from a few centimetres to around 1m high. Their flowers generally appear between February and June. The blooms can be tiny or large, in almost every colour imaginable, and can last for up to six weeks. Dendrobiums reproduce by forming baby plantlets, called keikis.
Dendrobiums make excellent houseplants. Most, such as Dendrobium nobile and D. speciosum, require cooler growing conditions and a less humid environment than the popular moth orchid, Phalaenopsis – 16°C-18°C is ideal. Grow in a bright spot and shield from direct sunlight. Water when the growing medium is becoming dry.
In autumn, reduce watering and move plants to a bright windowsill or porch, where they can remain cool and dry until spring. When temperatures increase in spring and flower buds begin to appear, water regularly and bring the plant indoors to a cool, bright spot.

Spotted a keiki?
Leave it attached to the mother until it has produced some new leaves at least a few inches big and has started to produce roots. You can then remove it from the mother and pot in up. While it establishes, give it a hand by regularly misting it.
