Rehmannia glutinosa
Rehmannia glutinosa, commonly known as adhesive rehmannia, is a species of flowering plant native to China and Japan. This perennial herb grows up to 1m in height and has a deep-rooted, woody stem. Its leaves are deep green, heart-shaped and covered in a thin layer of velvety hairs. Rehmannia glutinosa has attractive yellow and purple flowers, which bloom during the summer months. All parts of the plant have medicinal and therapeutic properties, particularly the root which has been used in traditional Chinese medicine for centuries. The prickly tuberous root can be dried and ground into a powder which acts as an antibacterial and anti-inflammatory agent. Adhesive rehmannia is an easy-to-grow plant and can be propagated from both cuttings and its seed pods.

watering
Adhesive rehmannia (Rehmannia glutinosa) should be watered once per week in the summer months, and less often in the fall and winter months (approximately every 2 weeks). The soil should be moist but not soaking wet. To check if the soil is dry, press your finger into the soil up to the first knuckle. If it’s dry, it’s time to water. In the summer months, it is important to watch the soil closely for dryness. If it starts to dry out too quickly, water more frequently.
sunlight
The adhesive rehmannia plant (Rehmannia glutinosa) prefers bright, indirect light and does best in full sun or partial shade. For best growth and flower production, it should receive at least 6 hours of direct sun per day. If grown indoors, it should be situated near a south-facing window for optimal sunlight exposure. If the adhesive rehmannia receives too much direct sunlight, its leaves may burn or become discolored. Therefore if grown outdoors, placement in an area with partial shade during the hottest parts of the day is recommended.
pruning
Adhesive rehmannia (Rehmannia glutinosa) should not require extensive pruning. Generally, only light pruning is necessary to remove old or dying branches, as well as any shoots that are competing for space. Pruning should be done in late winter or early spring, before new growth begins. Make sure to sterilize any pruning tools with a solution of rubbing alcohol and water to keep the risk of spreading any diseases low.
