Looking to add a splash of color to your garden? Consider incorporating blue plants that bring a bold and refreshing touch. Blue tones are not only visually attractive but also contribute to creating a calming, inviting atmosphere. If your garden is your peaceful retreat, blue plants can even lift your mood. As noted by Verywell Mind, “Blue evokes feelings of calmness and relaxation, and is often seen as peaceful, tranquil, secure, and organized.”
Here are 10 blue plants that will help you introduce serene shades into your garden.
1. Delphinium

This dramatic large cone flower will bring an element of intrigue to your garden. According to Jenn McComish, senior live goods merchant at The Home Depot, this plant is an excellent choice for drawing in bees, butterflies, and hummingbirds to your backyard retreat.
2. Plumbago

With stunning powder-blue blossoms, McComish notes that while this plant may seem fragile, it thrives in the heat and blooms year-round in the warmest regions of the country.
3. Evolvulus

This heat-loving annual thrives in the summer, adding a vibrant splash of color to borders, hanging baskets, and container gardens. McComish describes the striking evolvulus plant as “truly a show stopper.”
4. Salvia

McComish mentions that there are numerous varieties of salvia, ranging from annuals to perennials and even shrub types. She emphasizes, “These low-maintenance plants are reliable in the landscape and deliver color throughout the season.”
5. Hydrangea

Hydrangeas have long been a favorite in gardens. According to McComish, these flowers are “flashy, eye-catching, and over the top.” Beloved from spring to summer across the country, they come in various forms, ranging from patio trees to small, compact shrubs.
6. Muscari ‘Valerie Finnis’

According to Andrew Bunting, VP of Horticulture at the Pennsylvania Horticultural Society in Philadelphia, this blue plant is a small, hardy bulb that produces spikes of robin's egg-blue flowers. Bunting also highlights that it is deer resistant.
7. Amsonia hubrichtii

Often referred to as thread-leaf blue star, Bunting recommended this herbaceous perennial, which features sky blue star-shaped flowers and finely textured foliage. Additionally, it's deer resistant, making it an excellent choice for gardens where animals may roam.
8. Hosta “Blue Umbrellas”

Bunting shared that these plants feature striking blue leaves with a “sear-sucker-like surface” and are ideal for shaded areas.

Tara Nolan, from Savvy Gardening in Dundas, Ontario, Canada, and author of Gardening Your Front Yard, mentioned that this plant, with its heavenly-blue hue, is a favorite. Nolan said, “What I love about catmint is that it’s incredibly drought-tolerant in my front yard garden. It thrives in a sunny spot.”
10. “Blue By You” Salvia

Nolan mentioned that this newly popular blue-hued plant blooms for several weeks in her garden. She described the flowers as a blue-purple shade that contrasts beautifully with the green foliage.
