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.

Daylily
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.

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.

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!

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.

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.

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).
