It's a rose bud!
Use it for whatever you would use a regular rose for: Valentine's Day, sit around being pretty, ... actually I don't know what people use cut roses for.
Enjoy!

Requires no support but DOES require a brim.  Dual or single color capable.

Note: The render image shows the brim as a full base - there is not real flat cylindrical base to this model.
