POLIOMINTHA longiflora. Mexican Oregano. One of my recent favorites among the shrubby mints. It resembles the true oreganos closely in the aroma and flavor of the leaves, but is otherwise quite distinct. It grows about 2' tall, suckering freely from the base to produce small thickets. The slender twigs are lined by pairs of shiny, deep green, pointed-oval leaves. Tubular lavender blossoms, resembling those of the salvias, decorate the plant throughout the summer months. A good choice for dry, exposed banks. Sun, well drained soil, occasional watering when established. Hardy to 18^oF or less.
