Clerodendrum inerme is a hardy, salt-tolerant evergreen shrub or scrambling climber widely used for hedges, topiary and coastal landscaping. It has glossy green leaves and clusters of fragrant white tubular flowers with prominent purple stamens that attract butterflies. Exceptionally adaptable, it withstands sea spray, wind and poor soils, making it a favourite for beachfront gardens, boundary screens and clipped formal hedges. Fast-growing and responsive to shearing, it is easily shaped into dense walls or decorative forms. Tough, low-maintenance and tolerant of pruning, this versatile shrub thrives across coastal and inland regions of India.
