The 'Vanilla Strawberry' Hydrangea Tree, or Hydrangea paniculata ‘Renhy’, is a popular small-sized tree with vibrant blooms. Here’s why the Vanilla Strawberry Hydrangea Tree is the perfect addition to your garden:

Flowers: The main attraction of Vanilla Strawberry is its large, cone-shaped flower clusters. Its blooms emerge creamy-white by mid-summer, and transition to pink and later strawberry red by the fall. As it reblooms throughout the summer you'll see these three colors mix to create a truly memorable show.

Foliage: The foliage is dark green and has a serrated edge, providing a lush backdrop to the vibrant shades of pink-red flowers.

Growth Habit: Vanilla Strawberry Hydrangea is a short, compact tree that reaches only 6-7 feet high and 5-6 feet wide. It’s a great ornamental tree option for smaller spaces.

Sun Requirements: It prefers full sun to partial shade. Ample sunlight is essential for robust flower production.

Soil and Watering: Regular watering is required, especially during dry periods. Well-draining soil is ideal, but Vanilla Strawberry adapts to multiple soil types. Soil pH does not affect bloom color. 

Hardiness: This hydrangea is hardy in USDA Hardiness Zones 3 to 8.

Landscape Use: The Vanilla Strawberry Hydrangea Tree can be used as a focal point in the garden or for privacy. Its smaller size makes it suitable for urban or smaller garden spaces.

Pruning: Pruning is generally done in late winter or early spring. The previous year's growth can be pruned back to encourage a more compact and tidy appearance. Deadheading spent flowers can also promote continuous blooming.

Overall, Vanilla Strawberry Hydrangea Tree is valued for its vibrant blooms and small size. Its incredible flowers and transitional colors through the changing seasons is sure to make it a favorite in your garden.
