Hey, not every plant can live at a botanical garden, right? Sometimes you wake up, stretch your leaves, and realize your new home is next to hot black asphalt.
Some plants know how to say, “Cool,” and make the best of it.\
Parking lots, walkways, and roadsides are the hardworking areas of your commercial property. Landscaping them takes smart choices and creative thinking. The challenges:
These pavement-side plants put up with a lot.
Consider these roadside landscaping ideas:
Not all plants can stand up to the harsh conditions of roadside landscaping. But these sturdy varieties won’t let you down:
You can actually walk on this low-lying evergreen ground cover. And it’s drought tolerant.
A pretty, grass-like plant, liriope is a Level Green favorite. It’s hardy, inexpensive, stands up to foot traffic, and offers a lush, wavy, grassy feel.
This native plant has beautiful, vibrant foliage in shades of green, yellow and burgundy. Plus it has thorns, great for deterring pedestrians from stomping through the plants — so it’s perfect for parking lot island design.
It’s also called firethorn, so yes, this one is thorny, too. But it also offers spectacular clusters of red or orange berries that emerge in the fall and stick around through the winter. And it’s drought tolerant.
Nothing breaks up a big expanse of pavement like pretty shade trees.
Adding trees in and around parking lots, walkways, and roadsides improves appearance, prevents soil erosion, and adds oxygen to the environment.
Planted areas also reduce storm water drainage problems, buffer wind and noise, and make passers-by and parking customers happy by providing cool shade.
But roadside landscaping can be harsh. The sun really bakes parking lots and other pavement and it’s made even worse by reflecting off adjacent buildings and cars.
These trees have to tolerate heat, drought, salt, and soil compaction.
Choose tough trees that can handle parking lot landscaping, like:
This beauty, with its gorgeous, drooping flower clusters ranging from red to pink to lavender to white, would brighten any parking lot landscaping.
It looks fragile and exotic, but is surprisingly hardy. These heat-lovers actually thrive in parking lots, blooming luxuriantly in the reflected heat off the pavement.
The Chinese elm adapts well to a wide range of soil types and does well in urban conditions. It thrives in drought and is resistant to Dutch elm disease, elm leaf beetle and Japanese beetle. Elms are also salt tolerant, which makes them a good choice for parking lot landscaping.
The Red Maple will grow most anywhere. You’ll find it growing in swamps, in the poorest dry soil, and most anywhere in between. Parking lots? Walkways? Roadsides? No problem.
Imagine it’s a hot sunny day and you nabbed a prime parking spot beneath the shade of a leafy, sheltering tree.
Then, splat! A messy piece of fruit hits your car, leaving a bright purple stain. Or, an ill-mannered bird deposits a messy dropping.
So much for your happy mood.
Not every tree is a good choice for parking lots and walkways.
Some trees have berries that fall and can stain cars. Some attract insects and birds.
Good choices:
Try ‘Red Sunset’ and “October Glory’ maples for their stunning fall foliage, and columnar oaks that grow tall and skinny rather than wide.
This graceful tree offers pretty branches and dark green leaves that turn soft yellow, orange and russet in autumn.
It’s also a great tree for the urban landscape, as it has a high tolerance for wind, pollution, drought, and compacted soils.
This pretty tree, with its pleasing shape, dense canopy and super-fragrant flowers, isn’t bothered by air pollution, poor drainage or compacted soil, making it a parking lot landscaping winner.
It does well in full sun to part shade, tolerates all soil types and has moderate drought tolerance.
Use white gravel instead of mulch in places like baking hot parking lot island design.
It’s easier on the budget — while mulch has to be replaced a couple times a year, gravel is a one-time expense.
It helps the environment, too. White gravel reflects light, so it keeps the area cooler. Black asphalt and dark mulch attract heat, making the entire area hot.
Your parking lot, walkway, and roadside landscaping goes through a lot in winter, too, from salt spray to snowplowing.
That’s why it’s a great idea to hire a commercial landscaping company that can also handle your snow and ice management.
Why is that good for your landscaping?
They’ve walked your sidewalks many times during the spring, winter and fall, so once winter hits they know exactly what size plow to use to clear the snow without damaging adjacent grass or beds.
When crews know your sidewalks are four feet wide, they won't bring in a five-foot-wide plow to clear them. That just invites damage.
They know where everything is planted, so they won’t push snow on top of planting beds.
If your snow removal company is also your landscaper, they have an extra interest in keeping your plant material safe from damage. They’ve worked hard to select it, plant it and care for it all year.
If a plant is damaged by snow removal and needs to be replaced, your landscaper knows exactly what it is and how to safely plant it. A separate snow removal company won't have that expertise.
Parking lot islands are pretty little spots of cool in your sprawling commercial property parking lot. They break up large expanses of hot pavement with shady spots of green plants and bright flowers.
But don’t plant them with grass. While grass is inexpensive and offers a nice carpet of green, it won’t stand up to the rigors of car exhaust and winter salt applications.
What to use instead? The tough plants we mentioned above, like creeping juniper or liriope, are tough and attractive options for parking lot island design.
How about bright but sturdy flowers? Try these:
Everybody loves this cheerful garden staple. These natives are great in mass plantings and hold up well in the tough conditions of parking lots and roadside landscaping.
Another garden favorite, it’s both pretty and sturdy, blooming heavily for several weeks in late summer.
There’s a daylily variety for everybody— tall, short, yellow, purple. Cover them with snow, spray them with salt — they bounce back, so they’re perfect for roadside landscaping.
Landscaping parking lots, walkways and roadsides means lots of pavement. And that means drainage issues.
A sloping property can encourage water to pool in low areas, which can cause flooding around entrances.
When water drains to a low spot near a building’s foundation, water can seep in. What to do?
Pavement is a necessity of commercial property life.
But your customers, potential residents, and tenants want to see green, leafy, shady appeal.
Partner with landscaping pros who know what greenery thrives despite the challenges of pavement.
