Why do croissants only bloom male flowers and not female flowers?

Special pollination mechanism. Croissants are pollinated by ticks. Female ticks need to open the male flowers, feed on the nectar in the male flowers, lay eggs in the flowers, mix the nectar and pollen to form small pieces, and finally take them away. In this process, ticks bring mixed pollen and nectar to another flower to realize pollination function, so claw honey only blooms male flowers. The female and male flowers of the genus Crotalaria are unisexual flowers of angiosperms. Only pistils without stamens or stamens are called female flowers, and only stamens without pistils are called male flowers.
