"I will give him my pleasure-garden"

Pleasure gardens or vatikas in Ancient India were primary spots of recreation, with many personal gardens being maintained by royals and the rich, for visitation and indulging in sensual enjoyment with spouses, lovers and consorts. The art of gardening is mentioned in Vatsayan's Kamasutra. Many travellers have mentioned elaborate gardens in their writings on ancient India.

The earliest Buddhist monasteries evolved from orchards and pleasure gardens that had been donated to the Buddha. The most famous of these were the Bamboo Grove (Venuvana) and Jīvaka’s Mango Grove at Rājagaha (now Rajgir) and Prince Jeta’s Park at Sāvatthi.

The Mahaparinirvana Sutta mentions how the Buddha described the serenity of Rajgir,  while residing at Griddhkuta (Vultures’ peak) - "Pleasant, Ananda, is Rājagaha, pleasant are these places. Whosoever, Ananda, has developed. Therefore the Tathagata could, if he so desired, remain throughout a world-period or until the end of it." 

An interesting blog, Women and the Garden, explores the history and the art of gardening and also throws insight on why gardening evolved in the Eastern part of the world.
