The hardiest sedum would have to be Sedum acre, also known as goldmoss stonecrop. This particular sedum is incredibly resilient and can withstand even the harshest of conditions. It is hardy all the way down to zone 3, which means it can survive in extremely cold regions, such as Minnesota.
I have personally seen Sedum acre thrive in a variety of challenging environments. Its ability to withstand freezing temperatures and still maintain its vibrant green color is truly remarkable. This sedum is a popular choice for gardeners in colder climates who want to add a touch of beauty to their landscape.
Another hardy sedum that is worth mentioning is Sedum spathulifolium, also known as broadleaf stonecrop. This sedum is native to a wide range of western North America, from British Columbia to Southern California. It has a slightly higher hardiness range, being able to survive in zones 5-9.
I have had the pleasure of working with Sedum spathulifolium in a landscaping project in California, and I was impressed by its ability to thrive in dry and rocky conditions. This sedum has a unique appearance with its broad, spoon-shaped leaves and vibrant yellow flowers. It adds a wonderful pop of color to any garden or landscape.
When it comes to hardiness, these two sedums are among the best choices for gardeners looking for plants that can withstand challenging conditions. Both Sedum acre and Sedum spathulifolium are known for their ability to thrive in a variety of climates and soil types.
In terms of care, these sedums are relatively low-maintenance. They are drought-tolerant and can handle poor soil conditions. However, they do prefer well-draining soil and full sun to thrive. It is important to avoid overwatering these sedums, as they are susceptible to root rot in overly moist conditions.
If you are looking for the hardiest sedum, you can’t go wrong with Sedum acre and Sedum spathulifolium. These sedums are not only incredibly resilient but also offer unique and beautiful characteristics that can enhance any garden or landscape. Whether you live in a cold climate or a dry region, these sedums are sure to thrive and bring joy to your outdoor space.
