And no im not talking about the thing you do to small girls.
Reason: It would be awesome as decoration along with poppies and flax. Also good for latter uses when you implement dyes.
For now it should be used in a quern along with a clay jar to get oil, which you can use in a latern to get light. But since this is not enough you could also use/make-it-mandatory it when frying things.
It should have the same design as flax, just yellow, please please please
