Summary

Justicia ladanoides, commonly known as Mediterranean Justicia, is a perennial herb native to a wide range of tropical Africa. It can be found in various habitats, including moist rainforests, dry savannahs, cultivated land, grasslands, and forest edges, from sea level up to elevations of 2,600 meters. It exhibits a moderate growth rate, reaching heights of 2-3 feet (0.6-0.9 meters) and spreading 1-2 feet (0.3-0.6 meters). This plant is characterized by its lance-shaped leaves and clusters of white, tubular flowers that bloom profusely in the summer and fall, attracting pollinators such as bees and butterflies.

Justicia is valued for its extended blooming period and adaptability to various soil types. It is often used in border plantings, rock gardens, and as part of Mediterranean-themed landscapes. While it prefers full sun to part shade, it is relatively drought-tolerant once established and can handle medium amounts of water. It is best suited to medium or fast-draining clay, loam, or sandy soils. Gardeners should be aware that although it is not typically prone to serious pests or diseases, it can suffer from root rot if overwatered or planted in poorly draining soils.CC BY-SA 4.0
