Various Weed Types for the Wilderness Generation

There are a lot of flowers in Minecraft but there are not that many weeds. Dandelions exist but they are rather colourful being yellow. Weeds are actually often very important for real world ecosystems and provide many benefits to the soil and animals that live among them. They are necessary for the Wild in Minecraft.

In Minecraft they can provide things like having to change navigation to avoid a bunch of thorny bushes that could hurt you very slightly or weeds that would slow you down. They would add More diversity than just grass and ferns. They can change the wilderness by making areas with an abundance of a type of weed pleasant or unsightly to look at. You can of course easily remove weeds if you do not like them.  

Weeds that would make great additions of Minecraft:

• Burdock (uncommon thorny plants that slightly hurt)
• Rumex/Docks (common weed found inland that is distinctive against grasses)
• Phragmite (slows you down and are found on shorelines and riversides) It could be 1-2 blocks tall and feature the distinctive seeds on the top
• Cattails (they are quite distinctive and pleasant to look at) Found less common than Phragmites and would replace sugar cane. Sugar cane can be moved to hotter biomes.

Mechanics

• Weeds would generate in bunches or nearby the same type of weeds when world generation occurs
• Using bonemeal on grass would spawn new weeds along with flowers (this creates a discentive when trying to obtain flowers)
• Some types of weeds could spawn more in different Biomes
