Ashoka Tree
Saraca asoca
📖 About this plant
The Ashoka Tree (Saraca asoca) is one of the most sacred and historically significant trees in India — revered in Hinduism, Buddhism, and Jainism for over 2,000 years. According to Hindu mythology, the Ashoka tree was planted in the gardens of Lord Indra, and the tree is associated with love, fertility, and the alleviation of sorrow (the name “Ashoka” in Sanskrit means “without sorrow” or “no grief”). In Buddhist tradition, it is said that the Buddha was born under an Ashoka tree in Lumbini. In Ramayana, the Ashoka Vatika (Ashoka grove) in Lanka is where Sita was held captive by Ravana. Beyond its religious and cultural significance, the Ashoka tree is also an important medicinal plant in Ayurveda — the bark is used to treat gynecological disorders (especially menorrhagia and dysmenorrhea), skin diseases, and as a uterine tonic. The tree is a small to medium-sized evergreen with a dense, spreading canopy. One of its most distinctive features is the flowers — they emerge in dense clusters directly from the trunk and main branches (a phenomenon called “cauliflory”), not from the branch tips. The flower clusters are orange-yellow when young, turning red with age, and are extremely fragrant. The new leaves are soft, drooping, and pinkish-red, gradually hardening to dark green — creating a beautiful colour show in spring. The tree is also a magnet for butterflies and is the larval host plant for several species.

💡 Care tips
- Plant in a location with morning sun and afternoon shade — Ashoka prefers partial shade in hot regions. Water regularly during the growing season; the plant does not tolerate drought well. Mulch heavily to retain soil moisture and feed the roots. Feed with balanced fertilizer every 6-8 weeks during the growing season. Prune only to remove dead or crossing branches — the tree has a naturally beautiful shape and does not need heavy pruning. The tree is slow-growing but long-lived — plant it where it has room to grow to its full size (6-9 m tall, 3-5 m wide). Young plants need protection from direct afternoon sun and cold winds. The tree is perfect for temple gardens, large landscapes, and as a specimen tree in parks. The flowers are extremely fragrant — plant near windows or outdoor seating areas to enjoy the scent. The tree is also suitable for bonsai due to its small leaves and slow growth.
