It is difficult to bring to flower ... I believe they must reach great size – five years, or more – before you can see flower!
This is the photo of my plant. It has stayed at my garden for more than 5 years. I treat it as that for other vandas. It’s a strong plant, and tolerate hot or cold weather here, but it does like warmer weather more. The plant seems to be a mature plant. Hope it would bloom this year.
