About False Heather

Mexican Heather or False Heather is a Mexican and Central American tender evergreen shrub grown as an annual across most of the US and as a low perennial in Florida and coastal California. Forming dense mounded plants 10 to 24 inches tall with fine hyssop-like foliage, it produces countless tiny six-petal lavender, pink, or white flowers from spring through frost. A popular border and container filler for its fine texture and constant bloom.

History

Illustrated historical scene for False Heather

Cuphea hyssopifolia, commonly called Mexican heather, false heather, or Hawaiian heather, is an evergreen subshrub native to Mexico and Guatemala. Spanish botanist Mariano Lagasca described the species in 1821, the epithet hyssopifolia alluding to its foliage resembling hyssop. The plant forms a dense 30 to 45 centimeter mound covered continuously in tiny six-petaled lavender, purple, pink, or white flowers from spring through frost.

Although hardy only to USDA zone 8 or 9, it handles heat, drought, and humidity excellently, making it a mainstay of Gulf Coast, California, and Hawaii landscape and container plantings as either a perennial or annual. Proven Winners and Monrovia release popular selections such as Allyson and FloriGlory, and the plant is naturalized in Hawaii and parts of Florida.

Native to Mexico and Guatemala, introduced to American horticulture in the 1800s and popular in Victorian bedding schemes. Remains a standard Florida and Southern California landscape plant, beloved for the constant stream of small flowers that feed butterflies and tiny native bees all season.
