Flower farming Java edition

For Java Edition, I would like to propose having the ability to use bonemeal on a one block tall flower of any kind to drop another of the same kind of flower, just like how it works in Bedrock Edition and on double tall flowers. It gets pretty tiring trying to harvest enough flowers to make the various dyes. So far the best way to do so is to find a plains biome and use a truck load of bone meal on grass blocks, and even then it takes forever to get enough flowers to make all the dye I need for my projects. Not only that, but it limits the player to where they can set up their home/base because they are basically forced to live near a plains biome if they want to be able to get the greatest variety of flowers from using bonemeal on grass blocks. Most biomes only spawn red and yellow flowers and thats it! Blue cornflowers are particularly sought after for me. I know I could get lots of blue dye from Lapis Lazuli, but I really don't want to waste my Lapis for dye, as I'm sure most players would agree.
