This is an orchid that likes to climb. It can grow very long and this plant was bought from MH nursery many years ago. I tied it the a soursop tree and over the years it has grown into a large plant with 4 growing branches. Recently 2 of the branches started to flower. The first one was so high up that its quite impossible for me to take a picture. This one is lower so I managed to get a close-up shot of the flower spike.
This orchid can really grow quite messy due to its rambling habit. I decided to grow it for nostalgic reason: my grandfather used to grow them when our old house was at Jalan Hock Chye. It would climb on top of the front gate and was very free flowering.
