Mangrove propagules can both breed and attract bees

In one of my survival worlds I got a mangrove propagule and there was a bee and th3y came towards me while I was holding the mangrove propagule ant the button to breed the bee showed up and I went in a test world and none of the other saplings worked but it would make sense for a cherry sapling because of the flowers but the mangrove propagule doesn't make any sense
