Each of these resilient plants thrives in challenging conditions, such as drought, poor soil, and harsh winters, returning each year with stunning blooms that brighten your garden.

Baptisia

Once established, Baptisia, commonly known as false indigo, can thrive for decades. In fact, several specimens in the Better Homes & Gardens Test Garden® have reliably bloomed every spring since their planting in the 1950s. This robust, shrub-like perennial produces elegant stalks adorned with blue, white, purple, or yellow flowers, which are followed by distinctive seedpods filled with seeds.

Practically indestructible, daylilies (Hemerocallis) thrive in nearly any sunny spot and are known for their prolific flowering. They are drought-tolerant, insect-resistant, and come in a vast array of colors and bicolors. Daylilies are available as early, mid, and late-season bloomers, so consider planting a mix in your garden for a continuous display of color throughout the season. Alternatively, you can choose repeat-blooming varieties that flower from spring until fall, ensuring your garden remains vibrant and lively.

Hosta

If you appreciate variety, hostas are an excellent choice for your garden. These shade-loving perennials come in hundreds of shapes, sizes, and colors, from giants that can reach up to 4 feet tall to diminutive varieties that only grow about 4 inches high. Known for their stunning foliage, hostas also produce beautiful flower spikes in shades of blue, white, or lavender during the summer, with flowering times varying by variety. These hardy plants are easy to care for and can be dug up and divided whenever you want to expand your collection or share with friends.

Garden Phlox

Every flower border should feature a generous helping of garden phlox. These timeless perennials produce large, fragrant flower heads that bloom from midsummer to fall, providing vibrant color and delightful scents to your garden. Available in a range of hues including pink, red, purple, white, and bicolor options, some varieties also boast variegated foliage for added visual interest. If you live in a humid climate, consider selecting mildew-resistant types to ensure your garden remains healthy. Garden phlox pairs beautifully with roses, coneflowers, and lilies, making it an excellent companion plant that enhances the overall beauty of your floral arrangements.

Hellebore

Just when it feels like winter will never end, hellebores bring a much-needed burst of color to the landscape. Often referred to as Lenten or Christmas roses due to their early blooming season, these hardy perennials thrive in shady areas, where their nodding flowers in shades of pink, white, rose, green, purple, yellow, spotted, or bicolored varieties brighten up dark corners of your garden. Hellebores make excellent companions for spring-flowering bulbs like Narcissus and Squill, enhancing the beauty of your early garden. Additionally, they are resistant to deer and rabbits, making them a reliable choice for a thriving garden.

Barrenwort

One of the best shade perennials, barrenwort (Epimedium spp.) is a true garden workhorse. This hardy groundcover provides not only colorful foliage but also lovely flowers. Its high drought resistance makes it an excellent choice for shady areas with dry soil. Depending on the variety and your region, Epimedium may even remain evergreen through the winter. This perennial spreads slowly, gradually carpeting your garden with vibrant color and texture, making it a fantastic addition to any shaded landscape.

Enhance your flower borders with the vibrant color and delightful fragrance of Oriental lilies (Lilium spp.). These stunning plants produce clusters of richly scented flowers from mid to late summer, showcasing a beautiful palette that includes pink, rose, white, pale orange, and cream. Many varieties are also adorned with speckles and stripes, adding further visual interest to your garden.

Oriental lilies are easy to grow from bulbs planted in either spring or fall. Keep in mind that some taller varieties may need support in windy locations, so it’s a good idea to set stakes in the ground while the plants are still young. Their exquisite blooms make excellent cut flowers, but be sure to remove the stamens before bringing them indoors to prevent any staining on your clothes. To maintain the health and vigor of your plants, remember to dig and divide the bulbs every few years in the fall.

Sedum

If you’re in search of a low-maintenance perennial, make sure to add sedums to your shopping list! These resilient plants come in a wide range of shapes, sizes, and colors, thriving in tough conditions without succumbing to heat, drought, winter cold, or pests. One popular variety is Dragon’s Blood sedum, known for its attractive red-and-green foliage and fast-growing creeping habit, making it an ideal groundcover for slopes. While sedums thrive in sunny spots, they can also tolerate part-sun conditions, making them versatile additions to any garden.

Russian Sage

Brighten up your late summer and fall garden with the stunning Russian sage (Perovskia atriplicifolia). This resilient perennial, native to central Asia, thrives in hot, dry conditions, making it a great choice for low-maintenance gardens. Its striking bluish-purple flowers bloom from mid to late summer, maintaining their vibrant color for weeks. Complemented by its aromatic, silvery foliage, Russian sage adds both beauty and texture to your landscape.

Catmint

When catmint (Nepeta spp.) is in bloom during spring and summer, it truly shines as the star of the garden. The entire plant becomes adorned with tall wands of vibrant blue flowers that are resilient to heat and drought. After the initial bloom, you can simply shear the plant back by a third of its height, and it will reward you with another wave of flowers in late summer and early fall. Taller varieties, reaching up to 3 feet high, make fantastic companions for roses, peonies, or ornamental grasses, creating a beautiful layered effect in your garden. For shorter catmints that grow around 12 inches tall, position them at the front edge of your garden beds for a charming border.

Native to the American prairie, coneflowers (Echinacea) are among the most popular and widely hybridized perennials in the country. In addition to single-flowering varieties, you can also find double and even triple-petal-packed options (though it’s important to note that flowers with heavy petal counts are not as beneficial for pollinators). The color palette for coneflowers ranges from the classic purplish-pink to vibrant shades of white, orange, yellow, and red. They bloom from early summer through fall, attracting a variety of birds and butterflies, making them a delightful addition to any garden.
