New gardeners join us every week and I want you to be part of our growing community. Also, please like this video and leave a comment telling me which of these plants you're most excited to try. Your support helps us create more content just like this. What are cold tolerant perennials? Let me start by explaining what we're really talking about here. Cold tolerant perennials are plants specifically designed by nature to handle brutal winters. These aren't delicate flowers that need special care. These are tough, reliable plants that survive freezing temperatures, heavy snow, and ice without complaining. The best part? They come back year after year. Once you plant them, they establish themselves deeper in the soil, getting stronger and more resilient. Unlike annuals that you replant every spring, perennials are a one-time investment that keeps giving back. These plants have special adaptations. Their root systems dig deep into the ground below the frost line where soil stays warmer. Their leaves and stems have developed ways to handle ice crystals forming inside them. Some plants even go completely dormant, essentially sleeping through the harshest months, then wake up ready to grow when temperatures rise. If you have a garden in a cold climate, these plants are your secret weapon. And if you live somewhere mild, many of these plants still thrive in your garden too. That's why I'm so excited to share them with you today. Hardy Cold Tolerant Perennial number one, Astilbe. Let's start with one of my personal favorites. Astilbe is a plant that brings elegance and movement to any garden space. The flowers look like feathery plumes or delicate clouds floating above the foliage. When you brush against the plant, those flowers seem to shimmer and dance. Astilbe really shines in partial shade areas. This is great if you have spots in your garden that don't get full sun. The plant typically grows between one and three feet tall, depending on the variety. The width spreads out nicely to about one to two feet, making it perfect for gardens with limited space or to tuck into corners and edges. What I love most about Astilbe is its texture. Even when the flowers have faded, the foliage provides visual interest throughout the season. The leaves are deeply cut and delicate looking, adding dimension to your garden design. Astilbe handles USDA hardiness zones four through nine beautifully. That means it thrives in many different climates across the country. Whether you live in the upper Midwest or down South, Astilbe can be part of your garden. The plant doesn't just survive in these zones, it actually flourishes. Once established, it becomes a reliable performer year after year. Plant Astilbe in soil that stays consistently moist but not waterlogged. Keep the area around the plant mulched to help retain moisture and protect the roots in winter. Hardy cold tolerant perennial number two, Autumn Joy Stone Crop. Now let's talk about a plant that's absolutely magical in autumn. Autumn Joy Stone Crop gives you visual interest from early summer all the way through winter. This plant is sometimes called autumn fire and you'll understand why when you see how the change. In early summer, clusters of pink flowers appear on top of thick sturdy stems. These flowers are held in flat-topped clusters called umbels. As the season progresses, something amazing happens. The pink blooms slowly deepen and develop coppery tones. By fall, the flowers have turned burnished red and bronze colors that just glow in the afternoon light. Even better, these dried flower heads stay on the plant through winter. They provide food for birds and add structure and beauty to your winter garden. I keep my stone crop flowers on the plant until spring just to enjoy them. Autumn Joy Stone Crop grows between one and two feet tall with a similar spread. The plant has thick fleshy leaves that store water, making it extremely drought tolerant once established. This succulent foliage is gray-green in color and adds texture even before the flowers bloom. This plant wants full sun to light shade and well-drained soil. It actually prefers drier conditions to wet ones. This makes it perfect for people who sometimes forget to water or who have naturally dry spots in their gardens. Once planted, Autumn Joy Stone Crop practically takes care of itself. The plant does beautifully in USDA Hardiness Zones 3 through 9. That's an incredibly wide range. This is one tough perennial that survives serious cold and still thrives. Many gardeners in Zone 3 report that their plants have been going strong for over a decade with minimal care. Hardy Cold Tolerant Perennial Number 3, Blazing Star. If you want to add vertical drama to your garden, Blazing Star is your plant. Also called Liatris, this perennial has flower spikes that shoot upward, creating strong vertical lines in garden beds and borders. Blazing Star flowers have a unique appearance. Instead of flowers blooming from the bottom of the spike upward like most plants, these flowers open from the top downward. This creates an interesting visual effect as the color gradually fills in the spike over time. The flowers come in shades of purple, pink, and white, depending on the variety you choose. Each tiny individual flower is tightly packed onto the main spike, creating a solid column of color. These flowers are also excellent for cutting. They last a long time in a vase, making them perfect for fresh flower arrangements. The plant typically reaches heights of 2 to 5 feet, depending on the variety you choose. The spread is about 1 to 2 feet, making Blazing Star a good vertical accent plant rather than a space-filling plant. Planted toward the middle or back of garden beds, where its height adds dimension without shading out smaller plants. Blazing Star needs full sun and well-draining soil to thrive. It's not fussy about soil quality, but it definitely prefers conditions on the drier side. Wet soil, especially during winter, can cause root rot. Make sure water drains away quickly around the plants. This perennial does extremely well in USDA Hardiness Zones 3 through 9. The plant can handle serious cold snaps and heavy snow. Once established, Blazing Star is incredibly reliable and comes back stronger each year. The plant has deep root systems that help it access water deep in the soil and also help it survive winter weather. These deep roots mean the plant rarely needs supplemental watering once it's established, even during dry spells. Hardy Cold Tolerant Perennial number four, Butterfly Milkweed. Here's a plant that does double duty in your garden. Butterfly Milkweed not only looks beautiful, but it also supports important pollinators. This plant is absolutely essential if you want to attract monarchs and other butterflies to your garden. Butterfly Milkweed displays bright orange flowers in flat clusters. The orange is so vibrant and eye-catching that you'll see it from across the garden. Some varieties have yellow or red orange flowers, but the bright orange is most common and most stunning. The plant grows between one and two feet tall with a spread of about one and a half feet. This compact size makes it perfect for flower gardens, pollinator gardens, or mixed borders. You can plant it in groups for more visual impact or use it as an accent plant mixed in with other perennials. The most important thing to know about Butterfly Milkweed is that it's a food source for monarch butterfly caterpillars. The caterpillars eat the foliage and flowers, which is exactly what we want. Yes, the plant will look a bit munched on during peak caterpillar season, but that's actually success. You're helping save monarchs, which are facing serious challenges in our world today. Adult butterflies visit the flowers for nectar. Bees also visit the flowers. Hummingbirds sometimes visit too. This plant is basically a restaurant and maternity ward for wildlife. Butterfly Milkweed wants full sun. Plant it in a location where it receives at least six to eight hours of direct sunlight daily. The plant also prefers well-draining soil and actually does best in somewhat drier conditions. It's another plant that doesn't appreciate wet feet. The plant is suited for USDA hardiness zones three through nine. This wide hardiness range means gardeners in most climates can grow this plant successfully. The plant has deep tap roots that help it survive winter and access deep soil moisture during dry periods. If you care about supporting butterflies and other pollinators, Butterfly Milkweed is a must-have plant. When you plant it, you're literally helping save a species. That's powerful gardening. Hardy cold tolerant perennial number five, Common Sage. Let me introduce you to a plant that serves double duty. Common sage is an edible herb that's also absolutely beautiful in the garden. If you love cooking, if you enjoy fresh herbs, if you want a plant that's both decorative and functional, sage is your answer. Common sage has soft velvety leaves that are gray green in color. These leaves are edible and delicious. Fresh sage leaves have a warm slightly peppery flavor that's perfect in cooking. You can use them fresh in teas, dried and poultry seasoning, or fresh in stuffing, soups, and meat dishes. The plant produces small flowers in shades of purple, blue, plink, or white depending on the variety. These flowers appear on spikes and are attractive to bees and other pollinators. The flowers are also edible and make pretty garnishes. Common sage grows to about one and a half to two and a half feet tall with a spread of about one and a half feet. This compact size makes it perfect for flower gardens, pollinator gardens, or mixed borders. You can plant it in groups for more visual impact or use it as an accent plant mixed in with other perennials. The most important thing to know about common sage is that it's a food source for monarch butterfly caterpillars. The caterpillars eat the foliage and flowers which is exactly what we want. Yes, the plant will look a bit munched on during peak caterpillar season, but that's actually success. You're helping save monarchs which are facing serious challenges in our world today. Building proof of common sage is about 18 to 24 inches tall. When the plant matures, it develops a woody base which is completely normal. Hardy, cold tolerant perennial number six. Creeping phlox is exactly what you need if you need a low growing ground cover that brings color to your garden. Creeping phlox spreads across the ground like a soft colorful carpet and it's absolutely charming. Creeping phlox stays short, usually only four to six inches tall, but it spreads outward nicely to about one to two feet wide creating a dense mat of foliage and flowers. This spreading habit makes it perfect for ground cover, for edging garden beds, for tucking into rock gardens, or for planting between stepping stones. The flowers appear in late spring and early summer. Colors range through pink, blue, purple, white, red, and even bicolors with contrasting eyes. The flowers are small and densely packed creating a solid blanket of color across the plant.

The plant tolerates USDA hardiness zones three through nine beautifully. It's incredibly cold hardy and often starts growing earlier in spring than other plants. Early spring blooms are always a delight after a long winter. Creeping phlox is very low maintenance once established. Water it regularly the first year to help establish a strong root system. After that, the plant usually needs water only during extended dry spells. Mulch around the plant to help retain moisture and regulate soil temperature. Prune back creeping phlox after flowering to prevent it from getting too thick and potentially harboring pests. Cut back about one-third of the plant. This keeps it looking fresh and promotes more compact growth. The trailing stems look beautiful cascading over the edges of raised beds, walls, or containers. Many gardeners use creeping phlox this way to create visual interest and soften hard landscape edges. Hardy cold tolerant perennial number seven, candy tuft, is another low-growing perennial that brings delicate beauty to your garden. This plant produces charming clusters of tiny flowers that seem to float above the foliage. The plant typically grows between 6 and 12 inches tall, spreading to about 12 to 18 inches wide. This makes it perfect for edging beds, for rock gardens, for container planting, or for mass planting for a colorful ground cover effect. Candy tuft flowers appear in clusters called core rims.

This keeps it compact and shapely. Candy tuft works beautifully in containers, rock gardens, raised beds, and along borders. It's an incredibly versatile plant that fits into many different garden designs. Hardy cold tolerant perennial number eight, dianthus. Dianthus is a flower lover's dream. These plants produce fragrant, charming flowers in an amazing range of colors. Gardeners have grown dianthus for centuries, and you'll understand why once you experience them.

You can divide Hostas in early spring to create more plants or to reduce the size of large clumps. Division is very simple. Just dig up the clump and pull it apart into sections, each with some roots and eyes. Hardy, cold tolerant perennial number 10, Hellebore. Let me finish with one of my absolute favorite plants. Hellebore, sometimes called Christmas Rose or Lenten Rose, brings flowers to your garden when almost nothing else is blooming. During late winter and early spring, when you desperately need color, Hellebore delivers. Hellebores are unique because they bloom incredibly early.

Mulch around the plants to keep soil cool and moist and to suppress weeds. Hellebore doesn't really like hot, dry conditions. Hellebores are rated for USDA hardiness sounds 4 through 9. The plants are incredibly cold hardy and reliable. Once established, Hellebores can live and bloom for decades with minimal care. The flowers last an incredibly long time. Individual Hellebore flowers can stay fresh for months. This is unusual and wonderful. The flowers gradually change color as they age, adding even more interest.

The flowers take a long time to open but eventually unfurl beautifully. Hellebore self-seeds readily in most gardens. This means you get new plants appearing around the original plant. You can let these seedlings grow or remove them to control spread. These 10 hardy cold tolerant perennials are just the beginning of what you can grow in your garden. Each one brings unique beauty, character, and reliability to your landscape. When you plant perennials, you're making a long-term investment in your garden.
