Do some research on Desmanthus species, Phalaris grass is another area to look into. Keep in mind it can be a pain to I.D grass, I have had no luck identifying either of these wild, but it can be done. Seeds for either are available cheap and can grow across most of north America, you could even extract from them in a relatively short period of time.

Travel like a king
Listen to the inner voice
A higher wisdom is at work for you
Conquering the stumbling blocks come easier
When the conqueror is in tune with the infinite
Every ending is a new beginning
Life is an endless unfoldment
Change your mind, and you change your relation to time
Free your mind and the rest will follow
