Mona Lavender (Plectranthus 'Mona Lavender') is a popular, fast-growing evergreen perennial shrub, reaching 18-24 inches tall with dark green foliage, purple undersides, and long-lasting spikes of lavender-purple flowers from late summer to fall. It thrives in partial shade, requires well-draining, nutrient-rich soil, and is frequently grown as a container plant or annual in cooler climates, while acting as a hardy perennial in USDA Zones 10-11.
