Heavenly Hydrangeas
May 2006
If heaven is landscaped with our most favorite
flowers (and surely it is), there must be plenty of
room among the clouds that's been allocated for
hydrangeas - those big, round, luxuriously fluffy
flowers that almost beg you to stick your face into
them so you can feel their softness on your cheeks.
For some folks, hydrangeas conjure up nostalgic
memories of the big, pink or blue, ball-shaped
blossoms in their grandmother's garden. In today's
market, hydrangeas have become explosively popular
as cut flowers, especially when used in wedding
work. The massed, spherical form and supple texture
of hydrangea blooms makes them a preferred choice in
upscale floral arrangements. Rare indeed is the
'home interior' magazine these days that doesn't
show a picture or two of a bouquet of hydrangeas
among its pages.
Hydrangeas come in a wide variety of sizes, shapes
and colors, from climbing
vines to small trees. The potted hydrangea plants
most likely to be found in flower shops at this time
of year are the shrubby Bigleaf Hydrangeas
(Hydrangea macrophylla), which are sometimes also
known as Mophead Hydrangeas. For decades, these have
been the most popular hydrangeas for growing in
gardens and home landscapes. Bigleaf Hydrangeas are
beloved for their large, rounded flower heads, which
are actually composed of dozens of tightly clustered
individual florets. The showy flowers occur in a
range of colors, from the common pinks and blues to
more vivid purple, amethyst, and nearly red hues.
These flowers also come in white, which is
exceedingly popular in hydrangea bridal bouquets and
other wedding decorations.
An attractive variant of the Bigleaf Hydrangea is
the Lacecap Hydrangea. The inflorescence of the
Lacecap Hydrangea has a flattened center composed of
tiny, bead-like, unopened flower buds situated very
closely together. This compact center is surrounded
by a delicate ring of open florets, which seem to
hover weightlessly at the perimeter of the bloom.
Among hardy hydrangeas for the landscape, the
Oakleaf Hydrangea is the standout favorite. Easy to
care for, the Oakleaf Hydrangea (Hydrangea
quercifolia) is one of the few hydrangeas that are
native to the United States, the others hailing from
China and Japan. The Oakleaf Hydrangea is a
dramatic, white-flowering, deciduous shrub with four
seasons of interest. Its elongated panicles of
florets are persistent through the summer; its
large, deeply lobed leaves turn several shades of
orange and red in the fall, and the peeling bark on
its stems provides great winter texture. It blooms
best in areas where summers are somewhat hot, but
the Oakleaf Hydrangea is winter hardy further north
than the Bigleaf Hydrangea. A tremendous advantage
of the Oakleaf Hydrangea is that it can thrive in
much drier locations than its cousins (in fact, the
word "hydrangea" is Greek, meaning "water vessel" -
a reference to the majority of the species' extreme
need for water).
Hydrangea care is fairly easy. The most important
thing to remember is that hydrangeas love water (as
their name implies). Keep the soil of a potted
hydrangea moist at all times, without permitting it
to become waterlogged. Place the plant in a bright
location away from strong, direct sunlight. Keep the
hydrangea in as cool a location as possible,
especially at night, to prolong blooming. When
blooms have faded, and after any danger of frost,
the hydrangea may be planted outside. Cut the plants
back, removing the spent blossoms. Plant hydrangeas
in a rich, loamy soil in a semi-shaded location that
gets plenty of moisture. Florist hydrangeas are
generally hardy to USDA Climate Zone 6, but may need
protection from winter freezing that far north.
Bigleaf Hydrangea plants bloom on the previous
summer's growth, so in order to preserve the next
season's flower buds, prune im! mediately after
flowering, if necessary. Care must be taken never to
prune them during winter or spring.
With extra care, it is sometimes possible to change
the flower color on the Bigleaf Hydrangea. It has to
do with the acidity level of the soil and the
presence of available aluminum. To maintain or
change a hydrangea's flowers to pink, keep the soil
pH level around 6.0 to 6.2 or higher (hydrangeas
cannot assimilate aluminum at higher pH levels). Add
dolomitic lime to the soil several times a year to
raise the pH. Fertilize using a plant food that is
relatively high in phosphorous (the middle number in
the three-number ratio on the package), which also
prevents aluminum uptake.
To change the hydrangea's flower color to blue (or
to keep it that color), aluminum must be present in
the soil. Authorities recommend that a solution of ½
oz. (or 1 tbsp.) aluminum sulfate per gallon of
water be applied to plants (which are at least 2-3
years old) throughout the growing season. The pH of
the soil should be around 5.25 to 5.5 so as to make
the aluminum available to the plant. The soil should
also contain plenty of organic matter, such as peat
moss, which will tend to naturally acidify the soil.
Fertilize with a plant food that is relatively low
in phosphorus and high in potassium (the last number
in the analysis). In some native soils, however, it
may never be possible to change a hydrangea's color
to blue if the soil is highly alkaline (chalky).
Similarly, take care not to plant them next to a
concrete foundation or driveway since lime gradually
leaching from the concrete will make the soil
artificially high in pH. In that case, it may be be!
tter to grow your blue hydrangeas in big pots where
you can have better control over their care and the
soil makeup.
As
we noted earlier, hydrangeas have become very
popular for use in wedding work. The soft texture
and the voluptuous rounded form of the hydrangea
flower heads gives them a romantic, feminine appeal
that works well in wedding centerpieces. Their grand
size makes them appropriate for altar arrangements
at the wedding ceremony. A single, large hydrangea
bloom can even become the basis of a bridal bouquet,
with smaller flowers like roses or freesias arranged
around and through it.
Hydrangeas are among America's most favorite
flowers. They have a commanding presence in a summer
garden. They're lovely as cut flowers all year long.
For weddings, they can't be beat. And in spring,
long-lasting potted hydrangea plants are especially
nice as Mother's Day gifts! Your local florist can
arrange to have a big, beautiful, blooming hydrangea
plant delivered to your Mom, whether she lives
locally or out of town. Phone or stop in to place
your order, being sure to allow several days' notice
for best selection and timely delivery. With those
big, fluffy, cloud-like blossoms, hydrangeas might
just be a little bit of heaven on earth!
