Q: How large are 'Phantom' hydrangea flowers?
A: 'Phantom' produces the largest flower heads of any panicle hydrangea, with cone-shaped panicles reaching up to 15 inches (40 cm) long .

Q: Do the flowers change color?
A: Yes, the large panicles emerge in midsummer as creamy white with lime-green tints, then gradually mature to a soft, blushing pink as the season progresses into autumn .

Q: Does it need full sun?
A: It performs best in full sun to partial shade. In hotter climates, it benefits from some afternoon shade to prevent stress . It also requires consistently moist, well-drained soil, especially during the first growing season .

Q: When and how should I prune it?
A: Prune in late winter to early spring (January to March) before new growth begins. Since it blooms on new wood, you can cut it back hard to encourage vigorous new shoots and the largest possible flowers . This also helps maintain a compact shape and prevents the plant from getting too large.

Q: Is it resistant to flopping?
A: Yes, 'Phantom' is specifically selected for its strong, sturdy stems that hold the huge flower heads upright without flopping, even after rain or wind . This is a key advantage over many other large-flowered hydrangeas.
