About Ruellia coccinea
Ruellia coccinea, commonly known as Scarlet Ruellia or Wonder Herb, is a perennial herbaceous plant from the Acanthaceae family, prized for its vibrant scarlet-red tubular flowers. It forms dense, compact clumps, making it ideal for borders, rockeries, or as an accent plant in pots and containers in warm climates. Its abundant and continuous blooming attracts pollinators and adds a touch of tropical color to any garden.
Native range
Tropical Americas, including the Caribbean, Central America, and northern South America
Care tips
This plant thrives in full sun for optimal flowering, though it can tolerate some partial shade in very hot climates. Watering should be regular, keeping the soil moist but not waterlogged, especially during blooming periods, and reduced in winter. It prefers well-draining soil rich in organic matter; a universal potting mix blended with some coarse sand works well. Avoid over-fertilization, as it can promote foliage growth at the expense of flowers; a balanced fertilizer once a month during the growing season is usually sufficient.
