Q: How should I prune 'Annabelle' hydrangea?
A: Prune in late winter or early spring (before new growth emerges). Since it blooms on new wood, you can cut it back hard to 6-12 inches above the ground to encourage very large flowers and a compact habit, or simply remove dead stems for a taller plant with smaller blooms .

Q: Does it flower on old or new wood?
A: It flowers on new wood (the current season's growth), making it very reliable and hardy, as flower buds are not damaged by winter cold .

Q: Does the flower color change with soil pH?
A: No, unlike bigleaf hydrangeas (H. macrophylla), the flower color of 'Annabelle' is unaffected by soil pH and remains pure white. As the blooms age, they may fade to a soft, pale green .

Q: How much sun does it need?
A: It performs best in full sun to partial shade (at least 4-6 hours of sun). In hot summer climates, it benefits from afternoon shade to prevent wilting and protect the large flower heads .

Q: Are the flowers good for cutting?
A: Yes, the huge, long-lasting white flower heads make outstanding cut flowers and can be used fresh or dried for arrangements.
