Did you know that in several states of USA, it is illegal to buy or sell the ornamental plant Butomus
Flowering rush - Butomus umbellatus
Butomus is the sole genus in the monogeneric plant family Butomaceae, containing the single species Butomus
umbellatus, also known as flowering rush or grass rush.
The plant is a rhizomatous, hairless, perennial aquatic plant. Its name is derived from Greek
bous, meaning "cow", "ox" etc. and tome, a cut (the verb 'temnein' meaning
"to cut"), which refers to the plant's swordlike leaves. Butomus,
áccording Theophrastus, is from the Greek bous and temno, because the leaves cut the mouths of
cattle; and the second Latin name refers to the umbellate inflorescence.
