Mexican Heather

Cuphea hyssopifolia · Annual

Mexican Heather is grown as an annual, that matures to about 1–2 ft × 0.8–2.5 ft. It does best in full sun with medium water needs in well-drained, moist and occasionally-dry soil. Expect pink, purple and white blooms in fall and summer. It attracts bees, butterflies and hummingbirds, stands up well to heat, humidity and salt and grows happily in containers.
