Trials Update: 40 days with no rain, no problem for Southern Eucs Eucalyptus Trees!

Posted on December 21, 2016 by Ed Coughlin

The recent rains are a welcome sight for parched landscapes around the South.

Neither plant was irrigated, but an azalea falls victim to the drought, while a Eucalyptus 'Big O' still thrives.


In doing a little research I learned that, before recent rains, parts of Georgia were approaching 60 days without substantial rainfall!  That equates to the driest 3-month period on record!!!

One of six Eucalyptus 'Macarthurii', still in trials and planted just before the drought, finally gives in.

Five others Macarthurii fought off the drought and, following recent rains, look amazing.


On Nov. 17 the State Environmental Protection Division declared a Level 2 drought in 52 counties, including metro Atlanta, and much of North Georgia.

I watered once, out of pity on Nov. 23, but water just ran away from trees' roots.


This all follows the second-hottest summer in Atlanta’s recorded history,  Still, beside the Eucalyptus pauciflora - an alpine species that requires a damp, well drained soil - all the current Southern Eucs survived.


Pleased to report that Southern Eucs new spring introductions, Eucalyptus nova anglica 'Maggie' and parvula 'Funky Monkey' came through the drought unscathed.

"Grace" Under Fire; A story of survival of an abondoned Eucalyptus Tree

Posted on October 27, 2016 by Ed Coughlin

I can't recall the exact date, but my intentions were good when I offered to design and plant a small garden on a hard packed piece of land, owned by a quarry, but doubling as a soccer field. .


The location wasn't close to ideal for planting.  No irrigation, rocky soil, and a few hundred kids dribbling and drilling soccer balls right through it from Feb. to Oct.


But one of those kids was my daughter Maggie.  I'd sit and watch her evening practice, two hours, three times a week, and figured a little landscaping would go a long way to my sanity after those tough days at the office.


Knowing the plants would be tested, I loaded it up with tough selections like Juniper, Echinacea, and of course, a cold hardy Southern Euc.


I chose Eucalyptus elliptica 'Grace' because I like its fast growth, white bark,  durability, and dappled shade it would provide.

Maggie stopped playing soccer shortly after I finished the design, and I never really thought back to the quarry fields until just last week.  I was in the area and a little voice inside my head prodded me to take a look. 


I was disappointed to see the rough conditions of the fields and the little garden I planted.  But, avoiding the poison ivy, I pressed on, and to my surprise, nothing (besides the poison ivy) had endured the heat and neglect except one plant.

The Eucalyptus elliptica 'Grace' was the sole survivor.  Left for abandonment, with other plants known for toughness, it was "Grace Under Fire" in an onslaught of soccer, summer, drought, and debris!

Trials Update: 30' Growth & Stunning White bark in under 3 yrs.!

Posted on October 14, 2016 by Ed Coughlin

Most folks ITP (inside the perimeter) know that the East Atlanta neighborhood is the place to do some serious people watching, hear great music, or take in the Strut or East Atlanta Beer Fest.  Now you can add show-stopping Eucalyptus trees to their village voice.

Villagers pride themselves on thinking outside the box, and  new homeowner Scott Lootens wanted to make a statement fast, so he agreed to take part in the Southern Eucs Trials.  Both trees, started from seed less than three years ago, have not disappointed.  


The location gave Southern Eucs a zone 7b site and valuable feedback on how the trees would fare in a busy urban environment.


Eucalyptus neglecta 'Big 0' was planted to help screen a busy Glenwood Avenue.  In less than 3 years it has grown to 30' and attained a brilliant trunk and canopy. 


Eucalyptus are evergreens, offering  year round cover, but it's the way they pay compliments to the other deciduous trees, most notably this nearby Crape Myrtle, that grabs the eye.


Eucalyptus paucifloriia 'Bonza'  was planted as a specimen tree to help frame Looten's craftsman styled cottage.

It's the striking bark that really sets 'Bonza' apart.  White trunks are common in Birches and Aspens in the North and out West, but you would be hard pressed to find a smooth white trunk in a hardy tree that thrives in the South.

Trials Update: Southern Eucs in Poland Thriving in First Season!

Posted on September 29, 2016 by Ed Coughlin

Southern Eucs has over 7 official Trial Gardens with over 300 individual planting throughout the world.  One of the most exciting and unique locations debuted in March, 2016 when Shino Shino took delivery of 13 species of seed to plant in (zone 6b)Poland.    


It quickly became obvious that Southern Eucs first European Trials Master was serious about his craft.

Seed was sown and in no time Shino was communicating pertinent information on the trees germination and growth rate, susceptibility to fungus, and aesthetics.  

The trees, 6 mos. old from seed, are all flourishing.  No surprise four of Southern Eucs most popular and cold hardy species Eucalyptus neglecta 'Big 0', E. camphora 'Lucky Country', E. rubida 'Cab Sav', and E. stellulata 'Sheila' are thriving.

It's encouraging that Shino has had success with the difficult to seed and slower growing Eucalyptus pauc. 'Bonza'.


Even more excited to see next spring's new introductions Eucalyptus parvula 'Funky Monkey' and E. nova anglica 'Maggie' doing so well.


And highly anticipating Shino's feedback and hope to see similiar results with Eucalyptus perriniana 'Corker' which has yet to complete our 3-year trials.

Check back in early spring to see how the trees respond following the Polish winter!

The coolest and cruelest garden in the world!

Posted on July 07, 2016 by Ed Coughlin

I was in Cork for my good friend Steve McCarthy's wedding and had the chance to visit the infamous Blarney Castle, Ireland's own version of Graceland.

I was told the Castle also had some impressive gardens, so at the urging of my buddy, and famed wedding crasher, Jon Baime, I passed on a mid-day nap and made the short drive from Cork to Blarney.

The grounds were amazing with gardens of all shapes and sizes.

But it was the Poisonous Gardens at the base of the Castle that stopped me in my tracks.  One of the coolest and cruelest things I've ever seen.

So many common plants that are mainstays in U.S. gardens are potential killers, or at least dangerous bedfellows.

The iron cages hid the real bad boys like Deadly Nightshade, the king of killer plants.

  And our old friend Poison Ivy.

Interesting that they listed tobacco and marijuana (sorry Pep) for the potential harm they can bring to regular users.    

Same with Opium, but I had never seen the plant in person before.  The blooms are really something!

Some of the poisonous plants in the collection, that many of us enjoy in our home landscapes, were Sweet Shrub, Chaste Tree, Rhubarb (the leaf), Hellebores, Japanese Holly,  and Foxglove.  

No, Eucalyptus is not a  poisonous plant.  It's on the other end of the spectrum and has hundreds of medicinal purposes.  Saw this tree that had just been coppiced (cut back to promote new growth) just outside the poisonous gardens and thought it was ironic.

Finally, Harry Potter fans should be proud that author JK Rowling did her horticultural homework.  Wolfsbane, used by Hogwarts students to render dangerous beasts into sleepy wolves, is actually a nasty plant that tortures the stomach and slows the heart rate to deadly levels. 

And  Mandrake, another plant that's properties attack the vital organs, was also a favorite Potter plant.  Hogwarts students hurled it over the castle's embankments to ward off Death Eaters.

A visit to the Royal Botanical Gardens Pt. 3

Posted on July 04, 2016 by Ed Coughlin

A visit to the Royal Botanical Gardens in Edinburgh, Scotland is awe inspiring and leaves even a seasoned gardener in awe and envy.

Picking a favorite garden or plant is impossible, but the Mountain Tropical House kept me there well past the allotted time I had budgeted for each glass house visit.

Not only was the climate considerably cooler, to mimic higher altitudes, but the plant life seemed to grow from anything left on the ground for rot.

Thought I traced this moss and fern covered trunk back to its origin.

But counted three different varieties of Rhododendron growing from various points on the same rotted-out trunk.

There were some exotic cacti from all over the world in the Desert Climate House.

A little closer to home in was the American native Prickly Pear.

It was introduced to the Old World as a food source. Apparently the fruits are tasty and sweet.

Later introduced alongside Australia’s Eucalyptus trees, it was so happy in the dry arid climate that it now occupies over 24 million acres of the landscape.

And finally for the Lawn Lover’s out there.

Acres of pristine green stuff with hundreds of perennials in borders that seemed to go on forever.
