The rose, which is cultivated in these gardens, is said to have originally come from Busorah, and at Patna is culled by that name; but in Bengal it is called the Patna rose. It does not seem to differ materially from the common red rose of European gardens (Rosa gallica). It is propagated by cuttings in the rainy season. The cuttings are planted in a bed until they take root, and are then placed three or four together in one hole, the holes being from two to three cubits distant. Every two or three years the bushes are pruned. They flower from the middle of February to the middle of May, and must be watered in the dry season. The flowers, which are rather smaller than those in Europe, sell to the distillers at from 1000 to 4000 for the rupee.

Those who extract essences have several flower gardens at Patna and Bar. At the former two or three persons have rose-gardens, containing from one-fifth to one-third of an acre. The rose which is cultivated in these gardens is said to have originally come from Bussorah, and at Patna is called by that name; but in Bengal it is called the Patna rose. It is propagated by cuttings in the rainy season, and flowers from the middle of February to the middle of May, and during the dry season must be watered. The flowers, which are rather smaller than those of Europe, sell to the distilleries at from 1,000 to 4,000 per rupee, and are allowed to expand fully before they are sold.
