Araucaria columnaris, known in India as the Christmas Tree or Cook Pine, is a striking evergreen conifer with a tall, narrow, distinctly tiered silhouette and whorls of upward-curving branches clothed in soft, scale-like green foliage. Young plants make elegant, symmetrical specimens grown in pots indoors and on balconies, while mature trees become towering landscape features and are often planted as living Christmas trees. Native to New Caledonia, it adapts well to warm, frost-free Indian conditions. It prefers bright light, well-drained soil and protection from harsh dry winds, rewarding growers with a formal, architectural form year-round.
