It's the ground orchid, with two spikes.
Once this orchid blooms, it can go on and on for several weeks, with one bloom opens one day and the next bloom on the next day, and so on. And buds continue to form at the tip of the spike.
I planted these ground orchids in soil and treat them as other garden plants. They are quite easy to keep and bloom very regularly, not following a certain blooming season like other orchids. The white one blooms non-stop, you can hardly ever find it without blooming spikes!
Do you have ground orchids in your garden?
