People confuse corms and bulbs, myself included. Research says that if you cut them in half, a corm is solid and a bulb is made up of layers. That doesn't really help us unless we cut them! So I will now refer to them all as bulbs!
Bessera bulbs are dormant in the winter and bloom in the summer, similarly to a Gladiolus which are a corm too! Ugh!
I feel very lucky to have just a few of these bulbs in a pot. I was given them by my friend Bill McHenry after admiring them in his garden. It's good to have garden friends and to share plants.
