Mexican Oregano, Poliomintha maderensis ‘Lavender Spice’ is a wonderful addition to your Tucson and Green Valley area landscaping, suitable for a perennial and herb garden.
This lovely shrub with bright green leaves has a very long bloom period, with pink to lavender tubular flowers appearing in the spring through fall. Hummingbirds love this plant, so include this with some penstemon species.
Mexican Oregano prefers filtered or part shade and moderate water to produce the most flowers, although is quite drought tolerant once established. It is quite happy growing underneath our native trees, such as the Velvet Mesquite or Blue Palo Verde. It reaches about 3 feet tall and wide. The leaves are a perfect substitute for oregano in cooking.
Feel free to cut this plant back to make it bushier. The brittle stems are so easy to break off, you do not necessarily need to break out the snippers.
