The new Bletilla shoots appear during April and open out into a bouquet of leaves in the spring. The flowering is at its best at the beginning of the summer (June, July).

Following the flowering, the foliage, fairly persistent, remains green at least until October before fading and disappearing completely. Bletilla then go into their winter dormancy. At the end of November, when the leaves have faded, the floral scape can be cut, preserving a stem height of 5 cm.

Over the years and following the successive growth and dormancy cycles, Bletillas not only become stronger but also multiply, thanks to the annual appearance of new shoots.
