Amicia zygomeris is a striking perennial native to Mexico, valued for its bold foliage and unusual pea-like flowers. The stems are tall and angular, carrying large, bright green, heart-shaped leaves with purple stipules. In late summer, clusters of yellow and maroon flowers appear, adding exotic charm. It thrives in sheltered, sunny borders and makes a dramatic statement in temperate gardens.

Plant Type
Herbaceous perennial
This herbaceous perennial behaves as a subshrub in mild climates, dying back in cold regions and regrowing from the base in spring. It belongs to the pea family, Fabaceae, and is admired for both its structural foliage and decorative blooms. In frost-free areas, it may retain some stems year-round, lending it a semi-evergreen presence.
Mature Height
Up to 2 m (6.5 ft)
Amicia zygomeris typically grows to around 1.5–2 m (5–6.5 ft) tall and spreads to about 1 m (3 ft) wide. The upright stems give it an architectural quality, making it suitable for the middle or back of a mixed border. With adequate warmth and moisture, its lush growth forms a bold vertical accent through the growing season.
Light Requirements
Full sun
This plant prefers full sun for the best foliage colour and flower production, though it will tolerate light shade in hot climates. A sheltered position protects its tall stems from strong winds. When grown in partial shade, flowering may be reduced, but the foliage remains lush and attractive throughout the season.
Water Requirements
Moderate
Amicia zygomeris enjoys consistently moist but well-drained soil. Regular watering during dry spells keeps growth vigorous and prevents leaf scorch. It prefers humus-rich soil that retains moisture without becoming waterlogged. Mulching helps conserve moisture and protect the crown during winter in cooler regions.
Cold Hardiness
-5 °C (23 °F)
Hardy down to around -5 °C (23 °F), Amicia zygomeris tolerates light frost but may die back to the ground in colder weather. In areas with harsher winters, protect the crown with a thick mulch or overwinter in a frost-free greenhouse. New shoots emerge in spring once temperatures rise.
Propagation tips
Propagate by softwood cuttings in late spring or early summer, or by division in spring as new growth begins. Cuttings root easily in a warm, humid environment. Seeds can be sown but may take longer to establish. Protect young plants from frost and keep evenly moist during establishment.
