20 Durable Plants for Hot Weather

Every garden has challenges that you must tackle in order to be successful in creating a beautiful space. Long term, you can make it easier on yourself by choosing durable plants that are well-suited to the area you have in mind. 

 

Define what the challenges are in your garden and then start looking for plants that are well suited to thrive despite that challenge.  For many of us, the heat of a long summer is one of the primary situations to solve. The good news is there many plants that are tough and durable enough to thrive when the summer seems intent on roasting us and our plants too. Consider the annuals, perennials and shrubs listed below if you face long summers with quite a bit of heat and sunny days.  


 

HEART TO HEART Caladium

Common Name: Caladium

If you live in the South, Caladiums are probably already a staple in your garden and why wouldn’t they be? They absolutely adore hot weather. It’s not a matter of they “handle the heat just fine” – they prefer it to be hot. Which means they are perfect for places where the heat is sweltering. One of the things that make Heart to Heart Caladiums different from the rest is they are vigorous enough to perform well in more Northern climates too. Looking to add a splash of the tropics to your Michigan Garden?  Heart to Hearts are just what you need.  The second unique feature of our line is that in addition to traditional shade caladiums, about half of the Heart to Hearts will handle full sun as easily as they do shade – although keeping the soil moist will help them thrive in sun. There are 20 different options with a wide range of colors, sizes and leaf shapes to choose from.

Uses: Mass Landscape Planting, Front to Middle of the border, Thriller in Combination Recipes, Mono Baskets, Filler in Combination Recipes, Mono Patio Planters.

12-24” height. 12-24” spread. Some Shade only and some Sun or Shade. Annual, except frost-free zones.

 


 

SUNSTAR Pentas

Common Name: Egyptian Star Flower

If you live somewhere hot and have never tried Pentas, you don’t know what you’re missing - especially with our brand new Sunstar series. Sunstar boasts extra-large flower clusters nearly the size of hydrangea blooms atop well-branched plants. They have excellent summer durability, powering through high heat and humidity, and make ideal bedding and container plants for hot climates. They are medium-sized plants well suited to being planted in the middle of beds and can be thrillers and/or fillers in combinations planters. Butterflies, bees and hummingbirds are all attracted to the brightly colored flowers which will add another level of color and movement to your plantings. Now available in four colors – Red, Rose, Pink and Lavender.

Uses: Mono Patio Planters, Combination Recipes, Pollinator Gardens, In-ground Beds

18-22” height; 16-24” spread; part sun to sun. annual.

 


 

CAMPFIRE® Flame Bidens

This plant grows in a dense, compact mound. The flowers are fiery orange with a subtle yellow eye in cooler temperatures but become bicolor red and yellow as the summer heats up. The tight mounds remind me of mums. However, unlike mums, they bloom all summer long without deadheading. Pollinating bees enjoy the flowers which provide a consistent source of food for months on end. This plant is perfect for edging landscape borders and growing in smaller monoculture patio containers.

Uses: Garden Beds, Patio Planters, Landscape Borders, Pollinator Gardens

8-14” height; 10-16” spread; full sun. annual.

 


 

DIAMOND SNOW Euphorbia

Diamond Snow is similar to Diamond Frost®, but with fuller flowers and a somewhat denser habit. If you’ve never grown any of our Diamond Euphorbia you might take one look and think that the frilly plants will keel over at the slightest hint of hardship.  But nothing is further from the truth. Despite its delicate look, Diamond Snow is as tough and durable as they come. The plants are a reliable mound of color in upright containers and make a great landscape plant, too. Like all our euphorbias, expect Diamond Snow to power through heat, humidity, and drought with ease. For combination recipes, we suggest Diamond Frost, which weaves among other plants while Diamond Snow tends to be more of a mass of color in one spot.

Uses: Patio Planters, Garden Beds, Combination Recipes, Bright Shade Gardens

12-18” height; 12-18” spread. part sun to sun. annual.

 


 

HEAT IT UP Gaillardia

We’ve been incredibly impressed with this wonderful new Gaillardia series in trials all across the US and Canada. Heat it Up comes in two colors yellow and Scarlet. Heat it Up Yellow produces bouquets of fresh sunshine yellow flowers, while Heat it Up Scarlet has orange-red flowers with slight yellow tips.  The plants are extremely long blooming, lasting long into the fall even in hot, humid climates. The plants are very uniform in habit, express great vigor, come into bloom early and don't need to be deadheaded to bloom prolifically. They are great in landscapes and work as both fillers and spiller in container recipes. They are wonderful pollinator plants, I almost never see the plants without bees present. They are also attractive to butterflies.
