Seven Summer Sizzlers; Color That Keeps on Blooming
CONTAINED
BRILLIANCE
We all want our container plantings to stay full of color and texture, even on the hottest days of summer. With a little care and some smart plant choices, they absolutely can.
This week marks both the first official week of summer and National Pollinator Week. As container gardeners, we have a front row seat to the magic of bees, butterflies, and hummingbirds visiting our planters. So what better time to highlight plants that not only thrive in the heat but also support our buzzing, fluttering friends?
And while some flowering annuals and perennials start to fade as the summer heats up, others really shine. These are my personal favorites, the winners that reliably catch the eye, hold their shape, and keep the pollinators coming.
These seven summer sizzlers (plus a few honorable mentions) are sure to keep your containers looking beautiful all season long.
1. Begonia ‘Illumination Scarlet’
The Boliviensis begonias bring elegance and drama to containers. This variety, with its elongated leaves and profusion of large, double red-orange blooms, cascades gracefully over the edge of planters. It’s a standout long-blooming shade option that tolerates summer heat like a champ. Bonus: hummingbirds adore it too!
Size: 18” tall trailing to 30”.
Light: Part shade to full sun
Care Tip: Gently comb through and remove spent flowers. Snip below a bloom or at a leaf node to encourage more flowers and keep the plant tidy.
2. Calibrachoa ‘Bumble Bee Orange’
If you’re after a calibrachoa with bright, cheerful color and a bit of a flair, this one’s a standout. Its vivid tangerine bicolor blooms with ruby-red centers and yellow throats are a favorite among pollinators, especially butterflies. I love using it to add pops of color to a warm-toned palette.
Its lovely trailing habit is perfect for spilling over the edges of containers or cascading from hanging baskets.
Size: 6-12” tall, 12-24” spread
Light: Part shade to full sun (at least 3 hours)
Care Tip: Pinch back leggy growth to encourage bushiness and new buds. Trim mid-season if it starts looking straggly.
3. Canna ‘’Cannova Mango’
This showstopper brings tropical vibes, like an instant trip to the Caribbean. The lush green foliage is topped with showy salmon-colored blooms that radiate summer. Its compact form makes it a great choice for containers while still delivering BIG drama. It’s the perfect thriller or showpiece for a planting.
With repeat flowering, and a long bloom season, it thrives in summer heat. In warmer climates, it’s a perennial. In cooler areas like mine, treat it as a tropical annual.
Size: Up to 4’ tall
Light: Full sun
Care Tip: Water consistently, fertilize monthly. In colder climates, dig and store rhizomes indoors for winter.
4. Cuphea micropetala (Mexican Giant Cigar Plant)
If you’re looking for something with height, movement, and a little whimsy, this favorite is for you. Often called the candy corn plant, it earns its nickname from tubular blooms that line the upper foot of the stem. They open bright yellow and gradually fade to orange and red, looking just like candy corn kernels.
Hummingbirds flock to it, and butterflies too. It’s heat-loving, deer resistant, and just plain delightful. In warmer zones, you might see it return next year. In cooler climates, treat it as a beloved annual and enjoy every minute of it.
Size: Up to 3.5’ tall.
Light: Part sun to full sun
Care Tip: Cut back hard in late winter to encourage fresh spring growth. Drought tolerant once established.
5. Fucshia ‘Thomasina’
This is an excellent container fuchsia for sun or partial shade if you can find it. 'Thomasina' can be a bit tricky to track down, but she’s well worth the hunt. With a graceful arching habit and striking color palette, she adds elegance to any arrangement.
The terracotta-orange sepals with green tips and smoky red petals give her a painterly, almost vintage feel. She plays beautifully with soft, romantic tones but also holds her own alongside bold saturated colors. Whether you’re building a moody color palette or something more ethereal, ‘Thomasina’ will add class and blooms all season long.
Size: 12” tall and up to 30” wide.
Light: Part shade to part sun
Care Tip: Fertilize in spring. Gently shake to remove spent flowers and it will bloom from June to frost.
6. Pelargonium ‘Glory Days Red Orange Bicolor’
I first trialed this bold beauty from Dümmen Orange last summer, and I’ve been enamored ever since. It’s large, glowing red-orange bicolor flowers pack a punch and command attention, even from across the patio.
Part of the Glory Day series, it’s a new introduction, known for strong branching, big showy blooms, and impressive heat tolerance. It's a hybrid with zonal geranium leaves and ivy geranium habit.
Low-maintenance, it's a non-stop bloomer that delivers all season with very little fuss. Like most geraniums, a quick snip of spent flowers keeps it blooming and beautiful.
Size: 10-12" with trailing habit.
Light: Full sun (at least 6 hours)
Care Tip: Remove spent blooms regularly for continuous color.
7. Zinnia 'Profusion' Series
Is it even summer without Zinnias in a pot? These cheerful blooms practically shout warm weather, and the Profusion Series is perfect for container gardeners. With a compact, mounding habit, and endless blooms that burst with color, they’re a great alternative to more common choices like petunias or marigolds.
The series is a cross between Zinnia elegan and Z. angustifolia, combining the best traits of both: better disease resistance, drought tolerance and a longer bloom period.
Tough as nails and heat loving, these zinnias deliver nonstop color all summer. They’re pollinator magnets - hummingbirds and butterflies love them, and if you let the seed heads mature, you’ll see finches, juncos, and other birds snacking on them in fall.
Lately, I’m loving the apricot tones. My favorite of the series is ‘Double Deep Salmon’ though the ‘Double Hot Cherry’ is lovely as well. Whether used as fillers or a bold splash of color, zinnias always deliver.
Size: 12-18’ tall
Light: Full sun
Care Tip: Water consistently, fertilize monthly and deadhead to keep blooms coming.
Bonus: Honorable Mentions (Because I can’t stop at just seven)
Begonia ‘Dragon Wing Red’
This glossy-leaved beauty brings a bold statement of elegance without needing much babysitting. It thrives in bright indirect light (just avoid harsh midday rays), and the wing shaped leaves fill in lush and full while vibrant red blooms cascade in dramatic fashion.
It’s a low maintenance plant and reliably blooms from spring to fall, shining in those in-between spots that don’t get full sun. Whether paired with other plants or on its own in a container, ‘Dragon Wing Red’ brings a graceful, tropical elegance with very little fuss.
Size: 12"-24”
Light: Part Sun
Care: Lightly shake off spent blossoms. Deadheading not necessary.
Monarda 'Marje Purple'
This compact perennial adds bold color and a touch of fragrance to container plantings. It’s shaggy bluish purple flowers are a magnet for hummingbirds, while the deep dark green foliage releases a fresh minty basil scent when brushed.
Though technically a perennial, It grows quickly and thrives in containers, making it an excellence choice for seasonal plantings. ‘Purple Marje’ adds energy, texture, and makes for a lovely cut flower too.
Size: 12-24”
Light: Full Sun
Care: Lightly shake off spent blossoms. Deadheading not required.
Container gardening offers the benefit of less investment than a full landscape, and gives you more flexibility to try new things. So, this summer, go bold. Try something new, mix textures, play with color, and choose a few blooms that give back to the bees, butterflies and hummingbirds.
Many of these Summer Sizzlers can be purchased at your local nursery or from growers like Monrovia. Whether your brightening up a patio or simply celebrating the season, these favorites will keep your containers colorful, lively, and buzzing with visitors all summer long.
Let me know which ones you try this season. I’d love to hear! With a little care, you can plant more than flowers this year. You can create moments that last all season.
Happy Container Gardening!
