About Nettleleaf porterweed
Stachytarpheta urticifolia, commonly known as 'Nettleleaf Velvetberry', is a fast-growing tropical shrub featuring spikes of purple or blue flowers that attract butterflies and hummingbirds. Its leaves, reminiscent of nettles, are a vibrant green. It's an excellent choice for tropical gardens, as a border plant, or in large containers, where its continuous blooming adds a splash of color.
Native range
Tropical Americas, from southern Mexico to northern South America and the Antilles.
Care tips
This plant thrives in full sun for optimal blooming and requires well-drained soil, preferably rich in organic matter. Watering should be regular, keeping the substrate moist but not waterlogged, especially during dry spells. It tolerates some drought once established. A common mistake is neglecting pruning, which can lead to a leggy plant; regular pruning encourages compact growth and more flowers.
