Rhubarb

The rhubarb is a hardy plant
That humans found some uses for.
As a laxative it can grant
Relief from constipation more.
Though tart in taste, rhubarb does be
Cooked sweet with sugar for dessert.
But just the stalks are edibly.
The leaves contain poison to hurt.
Marco Polo and Ben Franklin,
Both fans, brought rhubarb near from far,
To open up new markets in
More places where more humans are.

Of course humans often dispute
Rhubarb - vegetable or fruit?
