Beautiful shrubs for the Garden!!

 
Old-fashioned Grandeur
Hydrangeas have been garden favorites for many years and understandably so! The diversity found in this family of flowering shrubs is impressive. They are usually grown for their large clusters of showy summer flowers but their value in the landscape goes well beyond their  beautiful blooms!

The Five Types
There are five different types of hydrangea and each has it's own unique characteristics. Most thrive in full sun or part shade and they prefer moist, well-drained soil that is rich in organic matter to perform their best. For pruning purposes, it is VERY important that you know which type(s) you have in your garden - so SAVE the LABELS!
See our 'Tip of the Month' for pruning methods.  

Hydrangea arborescens -
A wonderful species that includes the popular cultivar 'Annabelle' which produces huge white flowers up to 10" across. These hardy hydrangeas bloom from June - August and grow 3'-5' tall. This species prefers partial shade. The flowers are excellent for drying and using in fall arrangements. Zones 4-9.

Hydrangea paniculata - This tall variety grows as a large, upright, spreading shrub or it can be developed into tree form through pruning. It produces large conical flower clusters from July to September and grows 10' - 25' tall. One of the most cold hardy types of hydrangea. Zones 3-8.

Hydrangea macrophylla -
These are commonly grown hydrangeas that produce large
blooms on wood produced the previous year. This species includes the mophead hydrangeas with their huge round flower heads and the lacecap hydrangeas which bear round, flat clusters of tiny fertile flowers surrounded by a ring of showy open petals. The bloom color may be pink or blue depending on the pH of the soil they are grown in (blue in acidic soil, pink in basic or alkaline soil).
Lacecap hydrangea

The flowers of Hydrangea macrophylla are excellent for drying. This species is less hardy than the other species and in colder regions of Zone 6, they may grow well but not be "bloom hardy" meaning that the plant survives but never or rarely flowers because the flower buds are damaged during the winter. Protect the stems in winter by packing them with straw, tying them together, and wrapping them with burlap.
 
Reblooming Types 
Recently, several hardy reblooming cultivars have been developed from Hydrangea macrophylla. These include the Endless Summer Collection. These shrubs bloom on both new and old wood and are hardy to Zone 4.

Hydrangea quercifolia - Named for its deeply lobed oak-shaped leaves, Oakleaf hydrangea is noted for its brilliant deep reddish fall color. Large erect clusters of white flowers grace the shrub in summer with peak bloom in July. This species grows 4' - 8' tall and is hardy in Zones 5-9.

Hydrangea anomala ssp. petiolaris - This is a hardy climbing hydrangea which can reach up to 80' tall if left unpruned. The strong vines have attractive cinnamon brown bark and beautiful clusters of white flowers from June - July. They grow well on brick or stone walls, or on arbors and trellises. Zones 4-7.

Bottom Line
These are amazing shrubs and every gardener should find a place for at least one or two in the garden!
 
Come visit Viette's and see how magnificent these can be as mature specimens in the garden!

Pruning Hydrangeas! 

 

We always get a lot of questions on the radio, on our discussion board, and in our garden center about when is the correct time to prune hydrangeas. This is a great question because when and how you prune your hydrangeas can mean the difference between having multitudes of glorious blooms or . . . no blooms at all!
        
The
trick is knowing which of the five different types of hydrangea you have. So, when you plant, be sure to save the label! That way, when it is time to prune, you can do it correctly without sacrificing the beautiful blooms. Keep in mind that certain types of H. macrophylla may never bloom for you if they are not bloom hardy in your area .

Tips for Pruning Hydrangeas
Even though there are five different types of hydrangea, each of these falls into one of two pruning groups, based mostly on whether they bloom on wood produced in the current year (new wood) or wood produced in the previous year (old wood).
 
Pruning Group 1
This group includes the species that bloom on old wood - Hydrangea macrophylla (aka. mophead, lacecap, bigleaf, hortensia, or florist hydrangea) and Hydrangea quercifolia (oakleaf hydrangea).
Lacecap hydrangea
Lacecap hydrangea
  • Flower buds of these hydrangea are formed in August through October depending on the species.
  • These hydrangea do not necessarily require annual pruning. 
  • Prune these, if needed, right as the flowers begin to fade usually in mid-summer.  
  • To be safe, DO NOT prune them after July.
  • For mature established shrubs, the regular removal of 20% of the oldest stems (cut at soil level) will keep the plant vigorous and blooming well with larger flowers. Do this in the spring. 
  • Deadheading or removing the spent blooms can be done continuously through the season.
  • Some evidence indicates that leaving old blooms on the plant through the winter may help protect the tender buds below them. In colder areas, consider leaving them and removing them in the spring after the shrub breaks dormancy. 
  • Dead and damaged stems should be removed whenever they are noticed.
  • Oakleaf hydrangea does not require annual pruning and should be pruned mainly to remove dead or damaged stems or to limit its height.
  • Watch Mark's video tip on "Why Hydrangeas Don't Flower" 
Pruning Group 2
This group includes the species that bloom on new wood - Hydrangea arborescens (smooth hydrangea), Hydrangea paniculata (Panicle or PeeGee Hydrangea), Hydrangea anomala ssp. petiolaris (Climbing Hydrangea), and reblooming varieties of H. macrophylla such as the 'Endless Summer' Series.
Hydrangea 'Annabelle'
Hydrangea arborescens 'Annabelle'
  • These species of hydrangea produce flower buds on the current season's growth about one or two months before they bloom. 
  • In general, these can be pruned after they finish blooming up until they begin producing flower buds in the spring; i.e., fall, winter, or early spring. 
  • H. paniculata does not require annual pruning except to remove wayward branches and stems. This species can be developed into a single or multi-stemmed tree by maintaining just the desired number of stems/trunks and pruning out all but the upper branches. It can also be cut back to 18" - 24" from the ground to rejuvenate it or to limit its size. 
  • H. arborescens cultivars such as 'Annabelle' can be pruned to the ground in the fall or late winter before active growth begins in spring. This promotes large flowers! If your Annabelle hydrangea tends to flop over from the weight of the flowers, try pruning to 18" - 24" rather than cutting them to the ground. This will allow the stems to thicken and provide stronger support for the large blooms. Watch Mark's video tip on pruning Hydrangea 'Annabelle'
  • Reblooming types such as 'Endless Summer' can be deadheaded throughout the season to encourage continuous bloom.
    Climbing hydrangea
    Climbing hydrangea
  • Climbing hydrangea requires little pruning except to limit its growth to the space you have. Early spring or in summer after flowering is the best time to prune this species. 
  • Dead or damaged stems should always be removed whenever they are noticed.

Honey bees on goldenrod   08-27-2015 08:26:31 AM
It's late summer and your eyes have become itchy and watery. Your nose is running and stuffy because you've been sneezing like crazy. There must be some pollen in the air wreaking havoc with your respiratory system! You look around and see many bright yellow goldenrods in the fields and along the roadside so naturally [...] ...»

Speaking of Goldenrod ...

As summer comes to a close and the beautiful fall season is upon us, I am enjoying the last blooms of our daylilies, Coreopsis, hardy hibiscus, and summer phlox. But fall doesn't spell the end of color in the perennial garden. I am eagerly looking forward to the late blooms of Helianthus, goldenrods, chrysanthemums, sedums, and Japanese anemones.  Read more ... 

A Few Tips for September
  Now that the hot summer days are almost over, it's time to enjoy the garden again.
 
Extend Your Gardening Season
Hellianthus salicifolius produces masses of vibrant yellow blooms.

Go out and take a look at your garden - are the blooms fading away? Is the cheerful color of summer disappearing? Maybe your garden needs a face lift!
Now's the time to add some fall dazzle!
     
September is one of the best times to plant trees, shrubs, and of course, perennials!  
 
Fall Blooms
For your sunny area, the golden petals and deep brown centers of Helianthus and the Rudbeckia varieties give you rich, earthy color through the month of October.
Colorful Echinacea varieties
Colorful Echinacea varieties
Add some of the Echinacea cultivars for large, vibrant splashes of purple-red, orange, yellow, and white. Then there are the many varieties of our old favorites, the Asters, in their vivid purples, pinks, and blues; the Sedums, with their large, handsome blooms and interesting succulent foliage; the beautiful blue-gray, aromatic foliage of Perovskia with its graceful spikes of silvery-blue flowers; and the beautiful cobalt blue blooms and contrasting red fall foliage of Ceratostigma (Plumbago).       
     
Add a Garden Showpiece 
Crape Myrtle Sioux
Crape myrtles come in all sizes and bloom colors.
If you need a large "centerpiece" for your fall garden, consider the spectacular hardy Hibiscuswith its huge, colorful flowers or the long-blooming butterfly bush, Buddleia davidii, with beautiful flowers in many shades of purple, pink, and white that will continue to attract flocks of beautiful butterflies until frost. An excellent specimen tree or shrub for the fall garden is crape myrtle, Lagerstroemia indica. This exceptional deciduous ornamental has a long blooming season of showy flowers, a stunning fall season of blooms and colorful foliage, and a winter season of dramatic architectural beauty highlighted by distinctive cinnamon-colored exfoliating bark. What more could you ask for?  Anemone September Charm    
     
Fall Color for the Shade
For the shade garden, you must try Anemone japonica and hardy begonia, Begonia grandis! What wonderful late blooming perennials to compliment your Hosta, Astilbe, and other shade loving favorites.  
     
Color From Foliage

Don't forget the perennials which have such colorful foliage that they know no one season. Enhance the border garden with the beautiful red foliage of some of the new Heuchera varieties or the striking peach colored foliage of Heuchera 'Caramel'. The silvery Artemisia adds a softness to the stronger colors of Asters, Echinacea, and other perennials. The beautiful dwarf shrub,  Spiraea 'Gold Flame', turns from fiery gold in spring to a dazzling red, copper, and orange in the fall. Sourwood, Oxydendrum arboreum, turns a brilliant scarlet in the fall. It is a lovely understory tree to add to your landscape.
So many others ... Visit the gardens at Viette's or a public garden or arboretum near you to get more great ideas!

Dividing and Transplanting ...
      
Dividing daylilies Not only is September a great time for planting, it is also a great time to divide many perennials because the warm soil, increased likelihood of rain, and fewer insect and disease related problems combine to make perfect growing conditions for your new divisions. New roots will grow all winter and, come spring, will be strong enough to support lush new top growth. These divisions, supplemented with new perennials, can be used to create a new bed or to extend an existing garden.
     
When transplanting and/or dividing perennials that are already planted in the garden, you will want to cut the foliage back so the plant's energy can be directed to the roots instead of to the foliage and flowers. It will also reduce water loss through the leaves.
      
Always water deeply every 7-10 days after transplanting until the new plants have become established. Apply a 2"-3" cover of mulch after planting (except for peonies and tall bearded iris).
      
In general, fall blooming perennials like Chrysanthemums, Japanese anemones, ornamental grasses, and asters should be divided in the early spring before they begin growth.
