Give them a little water, decent soil, and a sunny spot, and they’ll reward you with nonstop beauty. Pick your favorites, plant them now, and let your garden shine all season.
#1 Zinnia
Zinnias bring an explosion of color that can make your garden feel alive even in the hottest months. These heat-loving blooms thrive in sunny spots, producing bright petals in jewel tones that last for weeks.
Keep the soil evenly moist and give them a light feeding every couple of weeks for their best show. They’re wonderful for cutting, too, so you can fill vases indoors without losing the outdoor display.
Plant them in clusters for a bold splash of summer cheer.
#2 Geranium
Geraniums are the kind of flowers that fit in anywhere, on patios, balconies, garden beds, or sunny windowsills. They reward you with long-lasting blooms and neat green foliage that stays attractive all season.
Water them when the topsoil feels dry and remove faded flowers to keep new ones coming. You’ll love how they brighten up containers and hanging baskets, making even small spaces feel lush.
#3 Calibrachoa Chameleon Sunshine Berry
This little beauty is a color-changing wonder. The blooms shift shades as the season progresses, giving you a new surprise every few weeks.
Grow them in hanging baskets or pots where you can admire their cascading form and vibrant hues up close. Keep the soil consistently moist and feed lightly to encourage constant flowering.
They’re a fun choice when you want something unique that feels fresh all summer.
#4 Marigold
Marigolds are as practical as they are beautiful. Their sunny blooms deter common garden pests while adding cheerful color to beds and borders.
Start them from seed or transplant young plants into well-drained soil in a sunny spot. Water regularly, especially during dry spells, and they’ll keep blooming for months.
Place them near vegetables to enjoy both their charm and their protective benefits.
#5 Petunia Night Sky
Petunia Night Sky is a flower that seems made for stargazers. Its deep purple petals are sprinkled with white, creating the illusion of a starry sky you can hold in your hands.
Plant them in hanging baskets or decorative pots to let their trailing stems shine. Give them full sun, keep the soil slightly moist, and feed every two weeks for an endless galaxy of blooms.
#6 Petunias
Few plants can match petunias for easy color. Their soft, pastel shades can soften hard edges and lift the look of any border or container.
Plant them in sunny spots, water when dry, and pinch off spent flowers to keep them blooming strong. They adapt well to most garden styles, so you can use them to blend with almost any theme you have in mind.
#7 Coleus Sea Monkey Purple
This compact coleus proves that foliage can be just as striking as flowers. Its deeply hued purple leaves and quirky shapes make it a standout in miniature gardens, rockeries, or container groupings.
Grow it in full sun for the richest color, and keep the soil lightly moist for best growth. Even without blooms, it delivers bold texture and color that lasts all summer.
