One of Olee's "extra interesting" plants is Lippia dulcis, common name "Aztec Sweet." Known to the Aztecs, the plant is said to be much, much sweeter than sugar. Leaves can be eaten or used to sweeten other foods, although a distinct camphor flavor discourages the latter. Lippia has been used to treat coughs, colds, bronchitis, and asthma. A low-growing perennial, it does well in shade and spreads quickly.
