Salvia Divinorum is a semi-tropical perennial. That means that Salvia Divinorum can grow year after year, but only if Salvia Divinorum is not exposed to freezing temperatures. Salvia Divinorum is a green plant with large leaves and a distinctive thick, hollow, square green stem. Salvia Divinorum can grow several meters (yards) high if conditions are favourable. When Salvia Divinorum grows high enough, the branches will bend, or break, and may root if they come in contact with moist earth. Although Salvia Divinorum can flower under natural lighting conditions, it almost never sets seed that will sprout.So the Salvia Divinorum plant is almost always propagated by cuttings. The leaves are oval, weakly notched (serrated) and can be quite large (up to 9 inches in length). They are usually emerald green, but under some conditions, may be yellow-green or even yellow. They are covered with a fine coating of extremely short hairs (trichomes), giving the leaves a satin like velvety appearance in certain lights. Salvia Divinorum plants grow best in partial shade, in well watered, but well drained, soil. The roots must not be kept constantly soaked, or root-rot will set in and kill the Salvia Divinorum plant.
