STRUCTURAL ELEMENTS TO ELEVATE YOUR LANDSCAPE

Winter is the perfect time to critically evaluate our gardens. With many of the plants in dormancy, the strength of our gardens’ bones is revealed. Take a winter walk through your property to determine whether it might benefit from the incorporation of the following structural elements:

 

EDGING

 

Whether lining a driveway with cobbles or defining the separation of the lawn and planting beds with brick, an edge makes a garden’s design stand out.

Brick defines this garden in Charleston.
At Mount Sharon (a Charles Stick garden), bluestone frames the lawn and draws the eye to the gazebo in the distance.

Cobbles separate the brick drive and lawn. A brick mowing edge (a rowlock flush with the lawn and perpendicular to a standing sailor) separates the lawn from the planting bed.

Groundcover is an excellent edger, if maintained properly. In this New Orleans garden, groundcover is planted in a robust swath, and provides a lovely natural frame to the (out of bloom) Agapanthus.


Cobblestone is an excellent edge for lawns. It holds up well to lawn mowers and string trimmers. Just be sure to take drainage into consideration when installing the cobbles.


WATER

A water feature can be a subtle addition to the garden, tucked into a corner, or a central feature. Be sure to add a spout or other means of water flow to prevent mosquitos and to add the alluring sound of moving water. When designing a water feature, I always make sure to soften and frame it with plants, to avoid a harsh assault of pavement.

This charming stone pool at The Priory in Wareham, England is tucked into a small garden, and contains plenty of pockets for perennials.

I separated this small pool from the stone walkway with a one foot wide bed of small periwinkle (Vinca minor).

This bog garden is also part of the Priory’s property.

An old brick wall is put to good use at Zero George in Charleston, where water spills into an Aubergine oil jar next to the hotel’s terrace.

At Pippin Hill Farm and Vineyards, outside Charlottesville, the capture of rainwater is transformed into a lovely water feature. The water is directed from the roof into this cistern, then channeled through a rill.


A stepping stone “bridge” is built over a small stream at the Coastal Maine Botanical Gardens, bringing the visitor closer to the wetland plants.


FRAMING AN ENTRANCE OR VIEW

Transitions are critical in a garden. Incorporate a gate, arbor or other feature that beckons to highlight the movement from one garden space to another.

This lattice fence separates two gardens in Princeton, New Jersey.

This wide lattice at Dumbarton Oaks in Georgetown (designed by Beatrix Farrand) separates two garden rooms, but also frames the view into that room.

Neighbors share this side entry from front to back gardens, with a tall picket fence and a rose covered arbor.

Charleston utilizes their minimal space between houses better than any city I’ve seen. Here, brick columns and a wrought iron gate provide the transition.

Climbing hydrangea clings to and spills over a lattice fence in Maine.

The opening in the old stone walls elevates what would otherwise be an insignificant path.


WALLS

Even the slightest change in grade in a garden is an opportunity to introduce a beautiful wall. Plants are always enhanced when enveloped by a wall made of natural materials.

This stone wall in Atlanta is softened by evergreens, including espaliered ligustrum.

This stone retaining wall in Kansas City levels a lawn that sloped to the curb.

We killed two birds with one stone (OK, many stones) in this garden when we built this seat wall opposite the entrance to a charming stone cottage.

A slight rise in the grade of this yard allowed us to introduce a drylaid stone wall to add interest to this Richmond garden. A Princeton garden took advantage of the same opportunity, below.


WALKWAYS

Circulation is the thread that holds a garden together. A garden should lead us from one space to another, sometimes subtly, other times audaciously. There is a hierarchy in landscape walkways. Broad paths, usually mortared, signal direction to a main entrance. Stepping stones set in the turf or garden bed lure the garden lover or the curious to, quite literally, get off the beaten path and explore.

This bold brick walkway plays off the curved bedlines, and takes a languorous route to the house.

Rectilinear stepping stones set firmly in the turf with a good stonedust base provide an excellent secondary garden path.

This secondary garden path, leading from the main terrace to a side terrace, is also effective. It is tumbled bluestone with sand joints.

Fieldstone bisects this perennial border.

Bluestone winds its way through a woodland garden. Anytime you have a bed deeper than 6 to 8 feet, you have the opportunity to run a stepping stone path through it. This helps with maintenance and allows the gardener to create a secret garden within the garden.

Grass is a fabulous path, and works well in country gardens.


FOCAL POINT

A well-designed landscape uses focal points to enhance the garden’s structure. A focal point can be a seat, an urn or some other garden ornament. It can be on an obvious axial point, or more subtly tucked into a corner of the garden.

This stone seat is along a woodland garden path at the Maine Botanical Garden.

This staddle stone, set in a lawn path at the Priory in Wareham, England, is beautifully framed by the Ware River and the natural stream-edge plantings.

These urns and pedestals in New Orleans echo the rectilinear garden design and flank the primary walkway.

This tuteur sits at the center of two intersecting paths, and so is seen from four viewpoints in the garden. A matching tuteur sits on axis from this one across the garden by the pool.

This iron bench and table sit on axis with the garden entrance.

A defunct tiered iron fountain was transformed into a lovely planter in this Richmond garden.

On a recent visit to London, I was captivated by the container plantings. This planting — espaliered magnolia underplanted with cyclamen in a converted galvanized tub — is repeated along this series of town houses.

GO VERTICAL! (IN THE GARDEN)

It’s often said that winter is the perfect time to study your garden’s bones.  As you do so, look up!  Pay special attention to your garden’s vertical elements.  Incorporating walls, fences, arbors, trellises, trees and shrubs  can solve many problems and will add interest and beauty to your landscape.

SEPARATION

DSC_0046

Whether you want to screen a driveway, gain a bit of privacy, or just provide transition from one garden space to another, vertical elements will do the job. A trellised fence takes up little space (depth) and provides a support for plants. In the picture above, Climbing Hydrangea (Hydrangea anomala subsp. petiolaris)  covers a fence.

DSC_0211

The tall picket fence and arched gate above tackle three issues:  they create separation  between front and back yards with a light touch, connect the buildings and provide support for roses.

 

At Dumbarton Oaks, below, a chain connected to stone pillars supports a Wisteria vine and creates a sense of enclosure.

DSC_0657

In another area of the gardens at Dumbarton Oaks in Georgetown, Wisteria is pruned to frame the beautiful latticework that physically separates the amphitheatre, without visually screening it. Beatrix Farrand, who designed the  gardens, was masterful in using vertical elements to shape the sloping land into separate terraced gardens with brilliant circulation from one garden to the next.

The latticed fence below, anchored by variegated Hosta, defines property lines and provides a connection between the neighbors’ gardens.

The front entrance, below, in this Kansas City neighborhood is beautifully defined by the stone and wrought iron fence and gate.

SEPARATION WITH PLANTS:  This fruit tree in Lasham, England (I think it was a Pear), one of several along an axis,  has been trained to bear fruit and separates the garden into two distinct spaces.

Charleston gardeners are some of the most talented vertical gardeners.  In the picture below, the hedge, punctuated by a line of Palmettos, is an effective screen of the parking area. While the English gardener uses the fruit trees, above,  only for definition, the Charleston hedge below is tasked with being a visually impenetrable screen.

I love the contrast in the English hedge below — tightly clipped (with flanking clipped sentries), yet with a fuzzy unkempt crown and surrounded by unmowed fields.

AN EXCUSE TO GROW PLANTS

Give a gardener a structure, and he or she will find a creative way to adorn it with plants. In the pictures below, a talented Princeton gardener espaliers Japanese Maples (Acer palmatum) and Japanese Hollies (Ilex crenata) on a humble cinderblock wall.

In the same Princeton garden, Climbing Hydrangea  frames a window.

Below, trellises supporting roses complement the architecture and strengthen the symmetry of a  formal garden.

No room to grow Figs or other fruit trees?  Espalier them along a wall or strong fence, as is done below.

The pale pink and white Camellias (Camellia japonica) growing on the simple gothic trellises transform an otherwise empty weathered concrete wall along a Charleston driveway.

Below, roses smother a thatch-roofed cottage in Lasham, England.

Vertical features don’t just create enclosure and define boundaries.  A tuteur or other plant support, like the one below sporting the native Passionflower Vine (Passiflora incarnata), acts as a focal point at Whilton, an exquisite garden near Charlottesville.

CANOPY

A mature tree canopy is an almost indispensable vertical element in the garden. Not only does it provide vertical interest, it offers shade and dappled light in the garden.   In the pictures below, allees are used to define space, act as a guide to a destination and reinforce a strong axial line.

Dumbarton Oaks, above.  Whilton, below.

Below, Plane Trees (Platanus x acerifolia) somewhere in Europe (9 years ago — can’t remember!).  The width of the path is inexplicably out of scale with the allee.

What a beautiful “ceiling” the mature canopy makes  at Dumbarton Oaks below.

DSC_0582 - Version 2

The native Sycamore (Platanus occidentalis), below, is host to a Climbing Hydrangea.  Never allow English Ivy (Hedera helix)  to climb a tree.  When growing any other vine, be sure to keep it under control, so that the vine does not inhibit the tree from producing the leaves necessary to thrive.

DSC_0155

The streetscape in Savannah, below, gives me hope for urban planting.  This strip bordering a commercial property was used to maximum effect.  The evergreens  were planted effectively between windows, then expertly pruned to frame the windows,  show off the multi-trunk effect artfully against the pale wall, and allow pedestrians to pass below the canopies.  They are underplanted with a simple ground cover.

And finally, have some fun with your vertical elements, as they did in the gardens at Whilton, below!

MID-SUMMER GARDEN CHORES

Since spring is now in the rearview mirror, it is time to . . .

CUT BACK HARDY GERANIUM, CATMINT AND LAVENDER

Geranium

 Cut flowering stems back once blooms begin to peter out.  The plants will begin to bloom again in a few weeks. Gernanium x ‘Johnson’s Blue’ is pictured above.

 PRUNE  SHRUB AND CLIMBING ROSES

Roses

Prune vigorously growing shrub roses (like Knockouts) back at least 12 inches, cutting each branch to just above a 5-leaf stem, to keep the roses from growing too big.  If you don’t mind them being 4 to 5 feet tall, just dead-head the spent clusters of blooms. Prune climbers as needed to train and keep under control. Feed roses every 6 weeks during the growing season (until early September).

CONTINUE TO CUT BACK LENTEN ROSE (HELLEBORUS) FLOWER STALKS AND LEAVES WHEN THEY BEGIN TO YELLOW

Hellebores

 PRUNE  STRAGGLY GROWTH OF EVERGREENS, IF NEEDED

July 2006 020

FEED AND DEAD-HEAD ANNUALS TO KEEP THEM BLOOMING

Reynolds

 REMOVE DYING FOLIAGE OF PLANTS GOING DORMANT

Virginia Bluebells

Virginia Bluebells (pictured above in background), Bleeding Heart, Arum and spring-flowering bulbs go dormant in summer.  Once the foliage begins to brown you can cut it to the ground.

WEED!!!!!
