Those are Calanthe vestita bulbs and Calanthe roseas. The bulbs have an hourglass shape, and the flowers are a bit smaller than those on the Calanthe vestitas, but very attractive.

The Calanthe vestita colony tray above started with 8 bulbs in the spring.

By the time this picture was taken in early October, the leaves were starting to turn brown...

...but a look underneath reveals that flower spikes are starting to emerge

In this picture, in early fall, the last leaves have died or been trimmed off, and the flower spikes are getting long enough to start showing flowers soon. For growing tips and a look behind the scenes at how I grow them, please visit my Calanthe Care page
