The "Little Lime" Hydrangea Tree (Hydrangea paniculata 'Little Lime') is a compact and dwarf version of the popular Limelight Hydrangea Tree. It is known for its smaller size, making it well-suited for smaller gardens or landscapes.

Here are some key features and information about the Little Lime Hydrangea Tree:

1. Type: Little Lime is a deciduous flowering tree belonging to the panicle hydrangea group (Hydrangea paniculata).

2. Size: Compared to its larger counterpart, Limelight Hydrangea, Little Lime is more compact. It typically reaches a height of 5 to 6 feet with a slightly smaller spread.

3. Flowers: The main attraction of Little Lime Tree is its large, cone-shaped flower clusters. The flowers emerge in mid to late summer and start as lime-green before gradually turning shades of pink, red, and burgundy in the fall. The color change adds to its ornamental appeal.

4. Foliage: The foliage is dark green and has a serrated edge. It provides a lush backdrop to the vibrant flowers.

5. Growth Habit: Little Lime has a rounded growth habit. It tends to be more compact and sturdy than some other hydrangea varieties.

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

7. Soil: Well-draining soil is ideal. Little Lime is adaptable to various soil types but prefers slightly acidic to neutral soil.

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

9. Landscape Use: Little Lime Hydrangea Tree can be used as a focal point in the garden, or as a container plant. Its smaller size makes it suitable for urban or smaller garden spaces.

10. 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.

Little Lime Hydrangea Tree is valued for its reliable and showy blooms, versatility in landscaping, and ease of care. As with other hydrangeas, factors such as soil pH can influence flower color. Providing consistent moisture, especially during dry periods, contributes to the health and vigor of the plant.
