Fun Facts
- 🌱 Candybelle hydrangeas change color based on soil pH: acidic soil (pH below 6.0) produces blue flowers, while neutral to alkaline soil (pH above 7.0) produces pink flowers. Intermediate pH levels create purple or mauve blooms.
- 🌱 Unlike many hydrangea varieties, Candybelle is a repeat-blooming cultivar, producing flowers continuously from early summer through fall, extending the display season by several months.
- 🌱 Hydrangeas are among the longest-blooming ornamental shrubs, with some flowers persisting on the plant for 2-3 months before fading to papery, dried flower heads that remain attractive well into winter.
