Factors' playing a role?
Hydrangeas are also popular browse
for deer, especially the flower buds, so if they commonly visit your
yard, they may be the culprits. If you find it necessary to prune
your hydrangea, do so as soon as it finishes blooming because it
starts setting next year’s flower buds soon after.
Of course, you
often see bigleaf hydrangeas blooming locally. That is common after
a very mild winter, or if they are planted in a protected location.
They also occasionally bloom from flower buds produced during the
current growing season (“blooming on new wood”). As a matter of
fact, plant breeders have exploited this tendency in order to
produce bigleaf hydrangeas that bloom reliably for gardeners in
colder climate. Known as the Endless Summer®
include the mophead forms Endless Summer®
and ‘Blushing Bride’
as well as a lacecap form called Twist-and-Shout™.
Hardy Sorts of
hydrangeas that are completely hardy for us include a vine, climbing
hydrangea (Hydrangea anomala subspecies petiolaris); and the
following shrubs: smooth hydrangea (Hydrangea arborescens); panicle
hydrangea (Hydrangea paniculata); and oakleaf hydrangea (Hydrangea
quercifolia). All typically have white flowers, although a new
smooth hydrangea called Bella Anna™
has been introduced that sports pink flowers.
Hydrangea paniculata 'Tardiva'
Tardiva Panicled Hydrangea
hydrangea and panicle hydrangea shrubs bloom on new wood. They can
be pruned in late winter or early spring when necessary. Oakleaf
hydrangeas flower on old wood and are best pruned as soon as they
hydrangeas do not require much pruning, only to retain their shape.
They are slow to get started, but can climb to 50 - 60 feet. Be sure
to provide adequate support for them, such as a sturdy wall, fence
or building. They climb by aerial rootlets, much like
