They also need some time to produce those spores. They don't spring up fully mature in the spring. They grow up, gather a little bit of energy, and very soon start producing spores, long before they are full-size. But when unfolded, the spore pods are there but not carrying spores quite yet.
Just like the mushrooms. They start producing spores a little before the gills open, and keep producing spores as long as they last. They don't pop up fully mature, either.
