The "Dog Days of Summer"

The Elizabeth Lawrence Garden fares amazingly well through the long dry periods we call the "dog days of summer".  (The dry spell started far too early this year... months before the traditional "dogs days" begin!)  The soil is so well-drained and the 5' elevation change of the property means any much-appreciated rain or city water disappears astonishingly rapidly.

Even so, phloxes bloom fluffy bunch after fluffy bunch, roses continue to open delicate cups of soft fragrance, Rudbeckia 'Henry Eihlers' still dazzles with spiky yellow stars of slender tube-shaped petals, doll's daisy (Boltonia asteroides) dances like a sliver of the milky way, and the ironweed's royal purple blooms sway in the slightest breeze.  Swallowtail butterflies flit from puff to puff of the joe pye weed (Eutrochium purpureum) while checkered skippers light on blooms of lantana and verbena-on-a-stick (Verbena bonariensis)Every once in a while, the staccato chirp of a hummingbird is heard near any of several species of Salvia in the garden.  And that's just a small list of blooms to be enjoyed - by all garden visitors!

Visit Miss Lawrence's garden for a refreshing retreat from the draining heat of the dog days of summer.  Open Fridays and Saturdays, 10 - 5.

Botanical Mystery Solved!

"I love being asked to identify plants, and I don’t know which gives me more pleasure: to know what they are or not to know what they are."
- Elizabeth Lawrence
Charlotte Observer
February 23, 1969 

As I stood in Miss Lawrence's garden on a sunny Saturday in early May, talking with Katie Mullen (former Elizabeth Lawrence Garden Associate and Marco Polo Stufano Fellow), I noticed blooms in the top of a narrowly conical evergreen tree on the east property line.  This is the first time I've seen any blooms on this tree since I've worked here.  I interrupted myself mid-sentence to point it out to Katie.  "I've been thinking that was some sort of Gordonia - loosely according to Miss Lawrence's records and not having seen a bloom ... but that's no Gordonia." I could feel the rush of adrenaline - I just adore solving a good botanical mystery.

We immediately went over to it and struggled to pull a branch down just far enough to snip off some small flowering branches.  We took the blooms into Miss Lawrence's studio for closer examination, and easier access to her index card database and bloom journals.  (That is usually the first place I go to solve botanical mysteries in her garden.)

Katie immediately whipped out her iPhone and started searching online.  She noted that the bark reminded her of a Prunus.  She followed her instincts, delving deeper into the cyberspace library as I, in true luddite fashion, flipped through Miss Lawrence's index cards.  No more than two minutes passed when Katie landed on a blog post and began reading the description given there of Prunus lyonii.  Sure enough, the flowers matched up beautifully to what was blooming here - a raceme of sweetly fragrant, white, wax-flower-esque blooms.  I imagine if I paid closer attention to an ever-present landscaper favorite go-to foundation shrub, Otto Luyken laurel, their flowers would be much the same.

So that helped narrow my search of Miss Lawrence's records, but I wasn't totally convinced of the tree's identity, yet.  I came across an index card describing Prunus illicifolia, which nearly perfectly fit the tree that stands like a rocket hiding behind two large Camellias.  But the evergreen leaves of the tree in the garden were only 2 1/2" long... shorter than those described.  I turned to Miss Lawrence's reference library for confirmation, plucking The Flowering Trees of California off the shelf.  There, I found exactly what I needed - the exact match of the plant before me: Prunus illicifolia ssp. lyonii.  Eureka!

Although I was a little sad that the internet seemed to initially trump a good old-fashioned paper search, it really only more quickly lighted the narrowing paper trail which ultimately led to the answer.  Regardless, the mystery is solved!  After years of admiring this fairly small but statuesque broad-leaved evergreen tree, now knowing its true identity is a small triumph - another small piece of the puzzle of Miss Lawrence's garden... this amazing garden that still provides plenty of inspiration, discovery, and botanical mysteries.

Until next time, I remain

Are you cruel enough to be a gardener?

For the past four years, I have kept a close eye on Miss Lawrence's Camellia sasanqua hedge at the sidewalk. It was not uncommon to see evidence of scale in the hedge, which had been kept sheared. Scale is an insect pest that feeds on plants by piercing plant tissue and sucking sap... literally sucking the life out of a plant. All kinds of scale like close, dark, humid quarters. In an effort to create a less hospitable environment for it, I thinned out some of the densest parts of the hedge last year. The intention was to increase air circulation and light.  While performing an annual plant assessment this winter, I realized that the scale infestation was quite severe. This was confirmed by local experts and members of my garden committee, as well as my gardening colleagues, Ben, Damou, and Danny, who have been battling scale on the oldest camellias in the Clarkson Garden.

During the process of educating myself on these nasty little vampiric creatures, I learned that there are several different species - most of which were attacking the hedge. Most were on the undersides of the leaves, but a lot were also on the limbs. Not good. Some species of scale are "easier" to control than others, but none are exactly "easy" to completely eradicate. So what does one do in a case like this?
Scale on the undersides of the leaves...
...and on the limbs.  Yuck.
The most important thing: do whatever I can to keep existing plants happy and healthy.  I weighed all of my options, keeping firmly in mind that many of the plants in the hedge are nearly 70 years old. Behind door number one, the less radical treatment - a regimen of chemical drenches, periodic spraying and pruning - over the course of years - which may or may not be completely effective in the end. (Ugh) Behind door number two, the more radical approach - renovate the hedge by pruning it way back, giving it a chance to regenerate with clean, healthy foliage that can be strategically pruned as it grows. (Seems drastic) And finally, behind door number three, the most radical approach - completely remove the existing hedge and start over. (Can you say "last resort"?)

It wasn't an easy decision, but the best option - and definitely most environmentally-friendly - was behind door number two: rejuvenation pruning... or, as I like to think of it, pressing the "reset" button.  Older plants usually respond better to hard pruning; they have well-established root systems that enable quicker regeneration. Plant maturity is definitely on my side for this one!

So Ben, Damou, Danny and I set to work, and in one afternoon, completed the first pass.  It's best to start off a pruning project like this by being a bit conservative with your cuts... you can always prune off more later. And I did.

After the first pass of rejuvenation pruning
Rejuvenation pruning complete!
Sometimes older gardens present difficult situations.  Hard decisions must be made.  Such was the case with the sudden death of most of Miss Lawrence's witch hazel, Hamamelis intermedia 'Jelena', which required the same type of severe pruning.  Thankfully, that turned out to be a success story.  I remain ever-hopeful (crossing my fingers, toes, and nose hairs) that rejuvenating Miss Lawrence's Camellia sasanqua hedge will reap similar results.  I suppose I am, after all, cruel enough to be a gardener.

Wing Haven's Top Ten Checklist

Get your garden ready for spring with Wing Haven’s helpful top ten checklist

1. Survey the Yard

Make note of tree limbs that should be removed or cabled, especially those that overhang structures. Hire an arborist to maintain large trees. Cut down last year's perennial foliage, and toss it into the compost pile. Rake mulch from beds planted with bulbs before foliage appears, and refresh mulch in other planting areas after soil warms. Check fences, steps, and pathways for disrepair caused by freezing and thawing.

2. Order Tools and Plants

Clean and sharpen your tools so everything is ready when things start growing. Make note of what is missing, and purchase tools for the new growing season. Choose new plants for the garden; order perennials, trees, and shrubs for spring planting.

3. Get Ready to Mow

Send the mower and leaf blower for servicing, or if you have the right tools, sharpen the mower blades yourself. Change the oil in your mower with oil, install fresh spark plugs, and lubricate moving parts if necessary. Clear the lawn of winter debris, and look for areas that need reseeding before mowing. Also, run through your irrigation system and inspect for potential winter damage.

4. Prune Trees and Shrubs

Remove dead, damaged, and diseased branches from woody plants. Thin and trim summer blooming shrubs such as butterfly bush, hydrangea, and most roses (except for old fashioned once bloomers). Prune cold damaged wood after plants resume spring growth. Prune spring blooming shrubs and trees after flowering.

5. Take a Soil Test

Check soil pH with a home soil test kit or send it off for more detailed analysis. Be sure to take several samples from different planting areas for an accurate reading. Enrich soil as necessary: Add dolomitic lime to raise the pH or elemental sulfur to lower the pH.

6. Prepare New Beds

Clear the planting area as soon as soil can be worked, removing turf, weeds, and debris. Spread a 4 inch layer of compost or well rotted
manure and any amendments over soil, and cultivate it to a depth of 10 to 12 inches with a spading

7. Plant

Install bare root trees, shrubs, and perennials such as hostas and day lilies by early spring. Choose a cool, cloudy day if possible. Plant containergrown
items anytime during the growing season except midsummer; be sure to water them thoroughly and frequently! Sow seeds of cool season flowers like sweet peas, poppies, and calendula, and vegetables such as lettuce, parsley, and spinach.

8. Fertilize

Apply balanced fertilizer (666 or 888),fish emulsion, or other soil amendments recommended by soil test results around trees and shrubs when new growth appears. Spread high acid fertilizer and pine needle mulch around acid loving shrubs like azaleas and camellias. Begin fertilizing perennials when active growth resumes.

9. Start a Compost Pile 

Start a compost pile, or use a compost bin, if you don't have one already. Begin by collecting plant debris and leaves raked up from the garden. Chop these up first to speed decomposition. Add equal amounts "brown" (carbon rich) materials like dried leaves and straw and "green" (nitrogenrich) materials like grass clippings and weeds in even layers with water and a compost bio activator. Turn regularly. Continue adding to the pile throughout the season for rich, homemade compost next spring.

10. Clean Bird Feeders and Baths

Disinfect the feeders by scrubbing with weak vinegar solution (1/4 cup vinegar: 2 gallons warm water). Rinse and dry the feeders thoroughly before refilling them. Scrub birdbaths with solution, then rinse them thoroughly and refill, changing water weekly. Clean bird baths and feeders regularly throughout the season.

It's a Blooming Winter!

"It seems to me that there is never a time when some living thing is not pushing up from the ground, and that at the beginning of the year there is a more vital stirring."
- Elizabeth Lawrence, Gardens in Winter

There are many wonderful winter blooms in Miss Lawrence's Garden right now. A few that she loved have become ones I, too, most cherish.  I thought I'd better capture their images today - before the rain and colder temperatures set in tomorrow.

Amur Adonis (Adonis amurensis 'Fuku Jukai')  Rare, nearly impossible to establish, this is not a plant for the faint of heart. The blooms remain perfect for weeks on end, come rain, snow, or below freezing temps. Every year that it begins to bloom tells me I haven't killed it, yet. Pshew!

Snowdrops (Galanthus sp.)  These easily-cultivated woodland charmers are a pristine delight no matter the weather, and, as with many little bulbs, are best planted en masse.  I can't talk enough about how awesome these are!

Roman Hyacinths (Hyacinthus orientalis)  These are not your run-of-the-mill hyacinths; these are the true original white hyacinths still blooming early every year in old southern gardens.  They come close to blooming on New Year's Day.  And the fragrance... oh, such sweet aroma!  They are the first hyacinths to bloom in Miss Lawrence's Garden.

Chinese Witchhazel (Hamamelis mollis 'Wisley Supreme')  A feast to the nose and the eye, this witchhazel greets me near the front door of Miss Lawrence's house with the cheeriest yellow blooms, and a delicate clean scent.  It's a great way to start the work day.  This was one of Elizabeth Lawrence's favorite winter blooming plants.

Come by soon to see what else is blooming; contrary to popular opinion, winter is a fantastic time to see flowers in Miss Lawrence's Garden.  (It's so great, she even wrote a whole book about Gardens in Winter.  It's my favorite of her manuscripts.  Grab a copy if you find one; it's out of print.)
