Succulents: The Cold-Hardy Champs
What are Succulents?
Succulents are a group of plants that have special adaptations, like thick, fleshy leaves or stems, to store water. They come in all shapes and sizes, from tiny groundcovers to towering trees. Many people think of succulents as desert plants, but they’re actually quite versatile and can grow in a variety of climates, even cold ones.
Zone 3 Hardy Succulents
Zone 3 is a cold climate zone, with average winter temperatures below -30 degrees Fahrenheit. But even in this chilly climate, there are a number of succulents that can thrive. These cold-hardy succulents are perfect for adding a touch of greenery to your winter landscape.
Some of the best zone 3 hardy succulents include:
- Sempervivum (hens and chicks): These succulents are known for their hardiness and can tolerate temperatures down to -30 degrees Fahrenheit. They’re also easy to grow and spread quickly, making them a great choice for groundcovers.
- Sedum (stonecrop): Sedums are another cold-hardy succulent that comes in a variety of shapes and sizes. They’re known for their attractive rosettes and clusters of tiny flowers.
- Jovibarba hirta: This lesser-known succulent is a low-growing, rosette-forming plant with rosy-pink and green leaves. It’s a great choice for adding a touch of color to your winter garden.
Marginal Cold Hardy Succulents
Some succulents that are hardy to USDA zone 4 can also survive in zone 3 if they’re given some protection from the cold. These succulents can be planted in sheltered areas, such as around rock walls or the foundation of your house. You can also use larger trees and vertical structures to create microclimates that may not experience the full brunt of winter as forcefully.
Some marginal cold hardy succulents for zone 3 include:
- Yucca glauca and Y. baccata: These zone 4 plants can survive many zone 3 winter experiences if they’re babied. Simply place blankets or burlap over the plants at night, removing them during the day, to protect them from the cold.
- Ice plants: Ice plants are hardy succulents that produce lovely little flowers and have a low, groundcover nature. They’re easy to grow and can spread quickly, making them a great choice for covering large areas.
Tips for Growing Succulents in Cold Climates
Here are a few tips for growing succulents in cold climates:
- Choose the right succulents: Not all succulents are created equal. Some are more cold-hardy than others. When choosing succulents for your zone 3 garden, be sure to select varieties that are known for their hardiness.
- Provide protection from the cold: Even cold-hardy succulents can benefit from some protection from the cold. Plant them in sheltered areas, such as around rock walls or the foundation of your house. You can also use larger trees and vertical structures to create microclimates that may not experience the full brunt of winter as forcefully.
- Use well-draining soil: Succulents don’t like to sit in wet soil. Be sure to plant them in well-draining soil that won’t hold onto water.
- Water sparingly: Succulents don’t need a lot of water, especially during the winter months. Water them only when the soil is completely dry.
- Fertilize lightly: Succulents don’t need a lot of fertilizer. Fertilize them lightly once a year in the spring.
With a little care, you can enjoy the beauty of succulents in your zone 3 garden all year long.
