False Heather (Cuphea hyssopifolia) is a tropical sub-shrub native to Mexico and Guatemala that brings delicate, profuse blooms to gardens in zones 9-11. Though called heather, it's not related to true heathers at all, belonging instead to the lythraceae family. Growing 1 to 2 feet tall with a rounded, densely branched habit, it produces small trumpet-shaped flowers with six spreading lavender petals that appear continuously from summer through frost. In cooler climates, gardeners grow it as an annual or container plant that can be overwintered indoors, while in warm zones it thrives as a low-maintenance perennial shrub.

The prolific blooming is what captures attention first, with delicate lavender flowers crowding the stems continuously through the growing season. The glossy, lance-shaped leaves stay dense and attractive even when the plant isn't in bloom, and the whole shrub maintains a naturally tidy, rounded form without demanding heavy pruning. Butterflies and hummingbirds visit regularly, and the plant handles both heat and some drought stress with ease, making it forgiving for gardeners in warm, sunny spots.
False Heather serves as an ornamental flowering shrub in warm-climate gardens where it provides continuous color from summer into frost. In cooler regions, it thrives as a container plant for patios and decks, bringing the same prolific lavender blooms in a portable form. It's also grown as a houseplant in warm, sunny indoor locations, particularly where gardeners want to overwinter tender plants between seasons.

Start seeds indoors 8-10 weeks before your last frost date, then transplant seedlings outdoors after frost danger passes and soil has warmed.
Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days before planting. Space plants 9-30 inches apart depending on desired mature size and density.

“Native to the tropical regions spanning from Mexico to Guatemala, False Heather arrived in cultivation as gardeners recognized the charm of its heather-like appearance and prolific flowering habit, despite the plant's lack of any botanical kinship to true heathers. The common name reflects this visual resemblance rather than taxonomic relationship, and the plant has been widely adopted in warm climates and as a tender annual or houseplant in cooler regions. Its ease of propagation from tip cuttings and reliable performance in containers helped it spread through the ornamental plant trade.”
