Plant Profile: Cuphea hyssopifolia

Mexican Heather, also known as False Heather, is a compact evergreen shrub that originates from Mexico, Guatemala, and Honduras. It has become established in Hawaii, where it is often regarded as a weed. This plant exhibits moderate salt tolerance and thrives in well-drained soils under full sunlight. While it can endure high summer temperatures and some drought conditions, it flourishes best with consistent moisture. Typically classified as a perennial in USDA zones 9 and above, it is more commonly cultivated as an annual.

The delicate lavender-purple flowers bloom individually at the leaf axils along the stem, creating a vibrant display that lasts until frost. This shrub typically reaches a height and width of about 2 feet, forming a rounded shape with multiple stems. In warmer climates or when grown indoors, it remains evergreen. Mexican Heather is ideal for use as a border plant, along pathways, or as a decorative container plant on patios or inside homes.
