When it comes to summer, for gardeners, it’s beautiful, colorful and fragrant flowers that grabs their hearts..

But, for all their hardiness in some ways, flowers can be delicate. Not all of them can stand up to the intense heat. And since most outdoor living happens in the high temperatures of summer, you need to plan for that.

If, however, when the month of June arrives, you realize you never planted spring bulbs, no worries. A beautiful landscape, spruced up with heat-tolerant flora, is still possible.

The weather in our area over the next week or so includes great planting weather. So we’re highlighting today a few plants that will stand up well to even long summer heatwaves and still thrive.

 

Hibiscus

People often think of hibiscus as a tropical flower — which it is. But it will thrive surprisingly well elsewhere, including the northeast. They do need lots of space, rich well-drained soil, and plenty of water but are worth the coddling.

Some varieties of hibiscus can grow into trees. How about that.

Verbena

Available in annual and perennial varieties (a total of 250 varieties in fact), this stunning flora is at its best during the hottest of summer heat.

With so many varieties, it’s a cinch to find a glorious purple specimen for your garden.

Often used in herbal teas, it’s beloved by more than humans. Yup. Butterflies and hummingbirds adore its blooms as well.

Some of the species are drought resistant, too, if that’s on your mind. They are often used in herbal teas. In addition, butterflies and hummingbirds love them.

Coneflowers 

One of our favorites for summer endurance is a wildflower — the Black-eyed Susan, a.k.a., coneflower. These plants are tough and take heat and bright sunshine well. They add gorgeous bursts of color to any garden, including around water gardens. And they don’t just turn the outdoors lovely. As cut flowers, they make great bouquets.

The following two photos celebrating coneflowers are from Deck and Patio projects.

Red Coleus

Again, we have a plant here that thrives in the sun. These beautifully leafed flora are great as container or bedding plants. It’s certainly a good time to add them to your gardens — or anywhere you’d like a spot of color — as they don’t survive during frost and cold climes unless you take them inside. If you plant them now they’ll thrive through the warm months…just pinch the tips from the stems regularly to help growth.

Globe Amaranth

This lovely annual looks like pom-poms; their flowers come in purple, red, and white and last into fall. Hardy as this plant is, do water it from the soil, not overhead, which can cause a powderly mildew to grow.

These plants will die back when frost appears, but their seeds will germinate after winter.

Purple Allium 

Although planted in fall, the Purple Allium Sphaerocephalon, seen in the foreground of this Deck and Patio project, is a summer blooming delight.

Its robust color thrives beautifully on Long Island and in the Northeast in general.

Deck and Patio landscape designers chose the Purple Allium here for its height, as well as the lovely color contrast it made against the green and yellows around it.

The plants first open green, and then mature to a bright crimson-purple. More good news. It’s rabbit, deer and rodent resistant and is loved by pollinators.

Outdoor Lighting

Speaking of Summer Nights, you can enjoy your backyard garden in the evening and at night (including late summer by adding the right flowers like asters)  —  if you’ve installed some landscape lighting. A beautifully lighted garden makes a perfect romantic setting that stimulates the sense of smell as well as sight.

Ahh. Summer days drifting away to oh oh the summer nights
