Hardy Hydrangea
These
Hydrangeas Bloom Every Year - Guaranteed
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." |
