when do bulb flowers form?

For sure. I was just expecting it to force one of the tiny dormant buds all
over the corm, but no. And those tiny dorman buds can expand to a
substantial sized leaf!

Out here, when fire goes through a redwood forest, sometimes all the
branches are burned off...the next year thousands of dormant buds burst
through the bark and the tree turns into a pale blue-green brush 30m
tall...once a few years pass, the branchlets compete out and the tree
begins to develop scaffolding branches again plus one apical stem.
