Syzygium campanulatum, popularly called Red Lip, Australian Brush Cherry or Kelat Paya, is an evergreen shrub or small tree in the Myrtaceae family. It is among the most popular hedging plants in Indian landscaping because its young leaves emerge in striking shades of fiery red and bronze before maturing to glossy deep green, giving the plant a constantly colourful, layered look.
Naturally dense and quick to bush out, it responds extremely well to clipping and is commonly trained into formal hedges, screens, balls and topiary. Small creamy-white powderpuff flowers appear in flushes and are occasionally followed by tiny purple-black berries.
Tolerant of heat, sun and routine pruning, it thrives in most Indian plains and is equally at home in large pots, along boundaries, or as a feature accent in gardens and commercial landscapes.
