15 Red Perennials That Bloom All Summer

Let's look at each of these scrumptious flowers to see which ones might be right for your garden.

Perennial forms—also called pinks—are evergreen or semi-evergreen. The name is derived from the petals' frilly edges, which look like they were cut with pinking shears. Sweet William and carnations are also types of Dianthus.

These flowers form mounded shapes and grow in Zones 3-9, depending upon the variety.

They like moderate,  six hours of sunlight but can tolerate partial shade though the blooms may not be as abundant.

Plant them in the spring or fall in rich, well-drained soil, and you'll enjoy blooms throughout the summer.

2. Roses

Rose (Rosacea) is a woody perennial flowering plant that comes in hundreds of variations.

Technically shrubs, roses come back every year, and rich red roses like red drift or knockout roses will give you masses of gorgeous blooms every year.

They thrive in full sun but can tolerate partial shade. Generally, roses like morning moisture, good air circulation, and well-drained soil. Roses do well with some help from fertilizers.

3. Valerian

Valerian is native to Europe and Asia but grows in the US as well. Valeriana Officinalis or garden heliotrope is known for its medicinal properties as well as its flowers.

Historically it was used to treat insomnia, migraine, fatigue, and stomach cramps.

Now it's used for insomnia, anxiety, depression, premenstrual syndrome (PMS), menopause symptoms, and headaches.

To grow valerian in your garden, it needs light, well-drained soil, and full sun to partial shade. It's cold-hardy and can be grown from seed or started plants.

4. Yarrow

Yarrow (Achillea millefolium) is a carefree pollinator, perfect for all types of perennial gardens.

The flowers may be yellow, red, pink, or any shade in between, so if you love it, you can have it in multiple colors.

Yarrow likes full sun, which encourages compact growth and flowers. In the partial sun, yarrow will grow leggy.

Yarrow does best in well-drained soil. It thrives in hot, dry conditions and doesn't like wet conditions at all. Space your plants a foot or two apart as they like to spread out.

5. Salvia

Salvia (also known as sage) or Lamiaceae is a gorgeous perennial. They're super for cutting and loved by bees and butterflies.

Salvia likes full sun and well-drained soil. They grow in containers as well as garden beds. Plant them in groupings of three or more plants for the best effect.

Each flower lasts only one day, but if planted in groupings, they produce many beautiful blooms. 

Daylilies do best in full sun but will tolerate some shade. They like highly acidic, moist soil and should be planted with plenty of space so that they do not have to compete with other plants for nutrients.

It needs at least six hours of sunlight per day to flower well, and if you're good about deadheading the blooms, you should have flowers from mid-June until the first frost.

These are a popular choice for low-water gardens as blanket flower thrives in low moisture conditions.

These flowers come in several colors, including a deep, almost-red pink.

For the best show of flowers, plant angelonia in late spring in a spot that receives full sun and has moist, well-drained soil.

Once established, these plants can be quite drought-tolerant, especially if the soil is rich in organic material and added mulch.

10. Ice Plant

Ice plant (Delosperma) is a hardy succulent ground cover that produces low-blooming flowers.

It's not called ice flower because of a cold-weather preference, but because both the leaves and flowers tend to shimmer in the sunlight due to the tiny hairs that cover the foliage.

They bloom in spring but can bloom again throughout the summer in sunny spots. These gorgeous plants look perfect in a rock garden where you need a low ground cover.

11. Primrose

Primrose (Primula vulgaris) are perennials known for their bright, beautiful flowers.

These are low-growing plants that form neat clumps of about 12" tall and wide.

They need well-drained, moist, fertile soils that imitate the woodland areas where they grow in the wild.

They grow best in partial shade and do better in places with cooler summers. In hotter climates, they are more of a spring perennial. 

12. Red Bee Balm

Bee Balm, also known as wild bergamot, is a very easy perennial to grow. It's a major pollinator attractor so perfect for a bee and butterfly garden.

It thrives in full sunshine and needs some space; otherwise, it's prone to powdery mildew on its leaves.

Coreopsis is relatively deer resistant and works well in fresh-cut arrangements making this a great addition to your perennial garden.

14. Red Verbena
