Native to China, this deciduous shrub is often called the Mexican Hydrangea, though it’s not a true hydrangea. It captivates gardeners with its large, fragrant blooms and adaptability to various settings.

Its growth habit allows it to thrive in both containers and full gardens, making it versatile for different spaces. Whether in a pot or directly in the ground, it adds a pop of color during the summer months.

For optimal growth, the Clerodendrum bungei prefers partial sun and consistent water. It flourishes in USDA zone 7 but can adapt to zone 6 with proper care. This plant’s seasonal cycle, with dormancy in winter and blooming in summer, makes it a great addition to garden designs seeking year-round interest.

How to Grow Mexican Hydrangea: Step-by-Step Guide

Success with the Clerodendrum bungei begins with careful site selection. This plant thrives in USDA zones 7 and can adapt to zone 6 with proper care. Choose a location with full sun to partial shade, ensuring it receives at least six hours of sunlight daily. Proper drainage is essential to prevent root rot, so avoid areas where water pools after rain.

When planting, wait until late spring or early summer when night temperatures stay above 50°F. Dig a hole twice the size of the plant’s root ball, adding organic matter like compost to improve soil quality. Space plants 3-4 feet apart to allow for mature growth. Water thoroughly after planting and keep the soil consistently moist during the first year.

Seasonal care is key. During summer, maintain regular watering and fertilize monthly with a balanced fertilizer. In fall, reduce watering as the plant prepares for dormancy. Apply a thick layer of mulch to protect roots from cold. By following these steps, you’ll enjoy vibrant blooms and healthy growth year after year.

Remember, proper site selection and consistent care will reward you with a robust, flowering shrub that enhances any garden. Start with the right conditions, and your Clerodendrum bungei will thrive, bringing beauty and life to your outdoor space.
