Appearance
Hydrangea Serrata Beni is a compact shrub that grows up to 1.5 meters in height and width. It has glossy, dark green leaves that are serrated and oval-shaped. The plant produces beautiful clusters of pink, red, or blue flowers that bloom in early summer and last until fall, depending on the variety.
The flower clusters are flat-topped and consist of both sterile and fertile flowers. The sterile flowers form the outer ring and are large and showy, while the fertile flowers are smaller and located at the center of the cluster. The color of the flowers depends on the pH level of the soil. Acidic soil produces blue flowers, while alkaline soil produces pink flowers.
Care Guide
Hydrangea Serrata Beni is relatively easy to care for and can thrive in a variety of growing conditions. Here are some care tips:
Water
Hydrangeas need regular watering to keep the soil moist. Water the plant deeply once a week, or more often if the weather is hot and dry. Avoid overwatering, as this can lead to root rot.
Fertilization
Feed the plant with a balanced fertilizer in early spring and mid-summer to promote healthy growth and blooming.
Soil
Hydrangeas prefer well-draining soil that is rich in organic matter. The soil should be slightly acidic with a pH between 5.2 and 6.2. Amend the soil with compost, peat moss, or other organic matter to improve drainage and fertility.
