Everyone knows that hydrangea are hot, hot, hot. But have
you ever thought about where breeding is taking
hydrangeas? For a
better
part on the United States the answer may be improved
hardiness and more reliable flowering.
French Hydrangea -Hydrangea macrophylla
is notorious its hit and miss flowering. This mysterious lack of flowers lies in
the flower buds. The flower buds are formed in early autumn and are
over-wintered. If the buds are
damaged by an early autumn frost, low winter temperatures, a late spring frost
or by an untimely pruning, the plant will not flower.
As the gardening public (and garden centers operators) begin to
understand that French hydrangeas are not reliable bloomers, they're going to be
looking for a hydrangea that is hardy and reliable.
Hardy
hydrangea - Hydrangea paniculata may
just be the plant everyone's been looking for.
It's a very hardy plant (USDA zone 4) and unlike the French hydrangea,
Hydrangea paniculata forms its
buds in early summer just before it blooms in mid-summer. This slight difference
in morphology ensures loads of reliable flowers. The flowers which appear in
July or August make great cut flowers or can be easily dried to create lovely
arrangements. Growing this hydrangea couldn't be easier. Plant it in full sun
and watch it grow. It's adaptable to a wide range of soils and has no serious
pests. For extra large flowers, plants can be cut back very hard in early
spring.
If
the this plant has any drawbacks, its that when we think of Hydrangea
paniculata we only think of the old fashioned cultivar 'Grandiflora' - Pee
Gee hydrangea. This old fashioned
plant, dating back to 1867, has large, almost gaudy flowers that flop every
which way. The good news is that
there are now improved, more refined selections that are just right for today's
garden.
The best new ones are 'Limelight', 'Little
Lamb', Quick Fire, and Pinky Winky
Limelight
Without a
doubt the best looking plant in my garden right now is
Limelight Hydrangea (Hydrangea paniculata ‘Limelight’). When
I first saw this plant in the Netherlands, my initial reaction was “Cool a
hydrangea with soft green flowers, ... but wouldn’t pink be ever better. After
getting the plant back to the U.S. and watching the plant grow, and watching
people’s reaction to the plant (especially the response from women), I began to
realize that this was one very special plant. After growing the plant for six
years I’ve come to realize that this plant is was one in a million.
Limelight has it all! Not only is it drop dead gorgeous, it is also a performer.
Gardeners from Orlando to Manitoba have sent me emails telling me how well this
plant delivers. A landscaper from Chicago told me that he uses the plant in
every design he creates. He told me that nearly all of his landscapes are in new
neighborhoods with few trees. Bigleaf Hydrangea (Hydrangea macrophylla)
reblooming or not, cannot take the heat and sun. They simply collapse under
these conditions. Limelight on the other hand thrives. It takes sun or shade,
sand or clay soils. In the North or in the South it has proven itself to be a
winner.
Besides its unique flowers and its superb adaptability, there are several other
things that make this plant a proven winner. It has very strong stems that hold
up its massive flowers even after a heavy rain. The old standard variety - Pee
Gee Hydrangea (Hydrangea
paniculata ‘Grandiflora’) deserves to be thrown on the compost heap
because it is notorious for collapsing under its own weight. Also, if you watch
Limelight closely you will notice just keeps sending up fresh new flowers. It
blooms continuously from mid-summer until frost. This results in a unique autumn
floral display - while the older flowers change from green to white to pink to
burgundy, new green flowers are added to the color mix. In the autumn this wide
range of flower colors is simply breathtaking.
Want to create something really incredible? A friend of mine has a 50 yard long
hedge of Limelight running along side his driveway. People whizzing past his
house at 55 mph literally slam on their breaks when they see it.
Limelight was developed by world renowned plantsman Pieter Zwijnenburg. Pieter
and his wife Anja own a nursery in Boskoop, Netherlands. Pieter received
the Pennsylvania Horticulture Society’s Gold Medal Award this spring in Chicago.
It was a well deserved award because Pieter is a very special person and
Limelight is a very special plant.

Pinky Winky - Hydrangea
paniculata ‘DVPpinky’ pp# 16,166
Pinky Winky is the creation of Dr. Johan Van Huylenbroeek, a well know
ornamental plant breeder within the Department of Plant Genetics and Breeding at
Flemish Institute for Agriculture. He developed this new variety by treating
seedlings of Hydrangea paniculata ‘Pink Diamond’ with the chemical mutagen
colchicine. In amongst the resulting seedlings emerged a superb new Hydrangea
that had just recently come to market in North America.

What makes Pinky Winky so special
and unique is its white and pink two-toned flower heads that appear in
mid-summer. The large, 16 inch long flower heads (panicles) emerge white and the
flowers at the base of the panicle quickly turn pink. The flowering is
indeterminate, meaning they continue to push new white flowers from the tip of
the panicle while the older flowers transform to rich pink. As an added bonus
the flower heads are held upright on strong stems and don’t droop like the ever
popular Pee Gee variety. The plant also exhibits dark green foliage which makes
for a nice backdrop for its beautiful flowers. Like all paniculata hydrangeas
Pinky Winky blooms regardless of climate, soil, pH or pruning. Use it as a
specimen plant or to create a spectacular flowering hedge.
Yes - Pinky Winky is a strange name for such a beautiful plant but it’s a name
you can’t forget. I ask Johan about the name and he told me it was derived from
a character on a children’s television program called
Teletubbies!
Despite the name, Pinky Winky Hydrangea will find a wide following with adults.
It is distinct, beautiful and easy to grow.
Little Lamb Hydrangea
Little Lamb is aa sweet new compact
hardy Hydrangea from Jelena DeBelder of Belgium. Little Lamb is unique because
it's flower petals are the smallest of any Hydrangea. These diminutive little
flowers are held in tight but delicate little flower heads that look like little
dancing lambs floating above this compact shrub. This special shrub blooms in
mid-summer and last into autumn. The pure white blooms light up a garden and
blend wonderfully with all other colors. Use The Little Lamb in bouquets either
fresh or dried to make a unique floral design. This is an easy to grow plant
with reliable flowering and flower color regardless of soil pH or winter
temperatures. The blooms are well
distributed making a very nice plant and
display.

Quick Fire
Hydrangea paniculata 'Bulk' ppaf
Quick Fire is a Hydrangea
breakthrough, in that it blooms months earlier that older varieties, extending
the bloom time and beauty from early summer thru autumn.Not
only does this variety bloom early, its blooms change from white to a rich
pinkish-red before other varieties even start to flower. A remarkable plant that
is changing the way we garden.This is a very hardy selection that blooms
reliably every year, no matter where you live or how you prune. Absolutely no
fussing or guessing like with other Hydrangea. Quick Fire is a blaze of color.

The genus Hydrangea is a wonderfully diverse and beautiful group of
garden plants. Their popularity is at an all time high.
Martha Steward Living, Horticulture
and Fine Gardening have all
created interest in Hydrangea but unfortunately the varieties she highlights are
not hardy or reliable blooming. These new selections of Hardy
Hydrangea may just the answer. They're hardy and they bloom reliably. They're
easy to grow, great for cutting or
drying and they attract butterflies.
As Martha would say "That's
a good Thing."
