Clematis make Great Companions

Friday, May 29th, 2009

Everywhere I look this spring in and around Atlanta gardens are lush.  What a differene rain makes.    I can almost hear the plants shouting  their thanks to Mother Nature.    While my roses and perennials have been prolific, the weeds are also keeping pace.  But   I’ll take the good with the bad, weeding is preferable to drought every time.

Among the  stars  in  my garden this spring one that stands out after three years is Clematis ‘Arabella.’  I added this non-climbing vine to my mixed border after discovering   it over four years ago in Lyndy Broder’s Stockbridge, Georgia garden.  A selection of Clematis integrifolia, it  thrives despite heat and humidity, producing masses of 2 to 3″ wide flowers that open deep purple blue and then fade to corn blue.  I let mine ramble and scramble through my border where it blooms for months beginning in May.  On a visit to Lyndy’s garden this spring where her collection of clematis now exceeds 150 varieties ‘Arabella’ was still one of my favorites.  Lyndy uses it throughout her garden as a groundcover and lets it mix and mingle with other perennials like hardy geraniums.

In fact most of the clematis Lyndy grows are paired up with other plants including shrubs, trees and perennials.  You can also grow many types in containers if space is a problem.    In mid-May there are dozens of combinations that make my mouth water  including Clematis texensis ‘Duchess of Albany’ with dark pink  2 inch wide tulip shaped flowers growing up and through  Rosa ‘New Dawn.’    Growing 6 to 12 ft. high, this vine needs a support or you can treat it as a groundcover.   In fall it produces attractive seedheads.  Selections of  Clematis  texensis are good choices for our hot climate.

A deep purple blue  clematis  that caught my eye was Clematis ‘Dominika’ which Lyndy grows with  Hydrangea paniculata ‘Limelight.’ The dark green foliage of the hydrangea provides the perfect background for this clematis.  And,  the hydrangea also acts like a  living trellis for ‘Dominika’  which begins blooming in May and continues for weeks.    Thriving in full sun, Lyndy explained that generally the darker colored varieties need more sun while the lighter colors, as well as  whites and bipolar like some shade.  Other tips from Lyndy about clematis I picked up on this visit include the fact that although they are popular, selections of Clematis x jackmanii are more prone to clematis wilt than varieties of Clematis viticella like ‘Etoile Violette,’ a profuse bloomer with deep purple flowers; a good choice for combining with pink roses like ‘New Dawn.’

I was also inspired by the way Lyndy  grew Clematis ‘Huldine.’  Its white flowers flushed with red streaks on the underside of the petals (tepals) glowed against the soft foliage of  Pseudolarix, a large conifer.

These are just a few combinations of clematis with other plants.  With some planning your garden can offer clematis blooms from spring until fall.  Most clematis require a moist, well-drained soil and full sun although there are types for shadier situations.  As far as the subject of when and how to prune, it all depends on when they bloom and whether a particular variety blooms on old or new wood.   Remember when in doubt, prune less rather than more.   For more information about clematis and their cultivation as well as recommended books, contact the American Clematis Society at www.clematis.org

Erica’s Pick: Rooguchi Clematis

Botanical name: Clematis ‘Rooguchi’

About the plant:  This free flowering hybrid clematis is covered with 2 inch cobalt blue flowers, blooming for weeks beginning in early May.  A hardy perennial, it dies back to the ground in winter but should return with vigor in the spring.

Use in the garden: Let this clambering vine weave itself up through shrubs or treat it like a groundcover.

Planting and Care: ‘Rooguchi’ will grow in full sun or part shade.  Give it a moist well-drained soil.

Meadow Gardening

Friday, May 15th, 2009

ox-eye-daisies-and-poppies-in-may 

Walking  in early May through masses of Ox-eye daisies, Chrysanthemum leucanthemum, Coreopsis lanceolata and poppies just beginning to bloom,  It’s hard to believe that just a few years ago this same area  was covered with kudzu and mulberries.  For artist Cooper Sanchez and his wife Michelle,  transforming their back yard in Clarkston, Georgia  into a meadow is a labor of love.  Creating a meadow garden was a vision they had early on. 

 Once established, and if it’s done properly, with consideration to the natural plant communities in your region, a meadow, unlike a lawn, is not only beautiful but can be low maintenance.   Meadow gardening is just one way to have a more sustainable landscape. 

I asked Cooper to tell me about how and what he did to begin his meadow.  He says that when he started he had to take down the mulberries to bring the kudzu to eye level.  “It was an acre of this-the hardest work you can imagine.”   He goes on to say one should be prepared as it will probably take two years to clear an area that is heavily infested with weeds.   He learned early on when trying to eradicate kudzu that you will never dig it all up.  He tried hand pulling and weed killers.    He found it effective to poison kudzu vines at the ground level rather than spraying the foliage.  (If you don’t want to use any chemicals you can cover large areas with black plastic with 3 to 4 inches of mulch on top of the plastic.  Leave the plastic for 2 to 3 months which should kill most of the weeds.)

 

Once he got rid of most of the weeds the soil had a fair bit of organic matter and he was ready to sow wildflower seeds.  Cooper selected and planted his first seeds 2 and a half years ago.  Fall is an ideal time in the South to sow wildflower seeds but you can also sow seeds in the spring.  He broadcast all of the seed by hand and has added some plants too.    The first year he had plenty of plants but many of the perennials did not bloom until this year.  Ox-eye daisies are  his spring work horse this year.  There are also yarrow, Achillea species, poppies and grasses.  As far as colors, at first he wanted to limit his palette to mostly white and warm colored flowers.  He thought that if he were going to have a potentially wild and unruly meadow, at least he would have a sympathetic color scheme.  Greens are also great and this year he has a lot more cool colors arriving on the scene.  And yet, it is only somewhat planned.  In addition to yarrow and coreopsis there are larkspurs of blue violet and other colors.  When I asked about the biggest surprise he replied that everyday there are more and more surprises including lots of bees, birds and other wildlife that is attracted to the meadow.  It turns out that some of the roadside weeds and native grasses  he rescued growing along railroad tracks and under power line easements are some of his favorites.    In fall the garden will turn shades of rust and brown.  I asked when he might mow down the meadow and he is not sure yet.  He makes reference to the Dutch garden designer Piet Oudolf who leaves his dead plants for structure in the winter garden waiting until the last minute to cut them down, maybe February.  Cooper says they will wait and see.  For now he looks forward to seeing what will bloom this summer.
