You all might think I'm 'nuts' for saying this, but I really do think bulbs get bigger and heavier and more robust over winter. This bulb sure is pretty isn't it! You can tell it's heavy! It looks like the bulb is starting to become more oval and will be dividing in another two or three growing seasons. Note the little bump stubs of stem roots just starting to grow.
On the other hand, I usually give the big ones away and keep the smaller ones for myself. Makes somebody really, really happy with joy!
