national PLANT NETWORK grower approved selections take the guesswork out of gardening. Heart Throb Hydrangea is a striking deciduous shrub known for its compact size and intensely colored flowers. The large mophead blooms open with green centers before maturing into a deep, vibrant red. The bloom color is directly determined by your soil's pH level, producing deep red flowers in alkaline soils and rich purple or maroon flowers in acidic soils. This hardy hydrangea is easy to grow and thrives in moist, well drained soil. Potted shrubs arrive ready to plant. For best results, plant in a location with morning sun and afternoon shade to protect the rich color of the blossoms, and water deeply 2 to 3 times a week. It is an excellent low maintenance choice for decorative patio containers, front borders, or small garden spaces.
