One variety of rosemary that is known for being cold hardy is Alcalde Cold Hardy. This particular type of rosemary is well-suited to withstand harsh winters, especially in areas with sub-zero temperatures. It has been observed to thrive in a northern New Mexico garden, where it has endured years of freezing temperatures without any issues.
Alcalde Cold Hardy rosemary is also highly adaptable to intense, high elevation summer sun. This is particularly beneficial for gardeners in regions with hot summers and strong sunlight, as the plant can withstand these conditions without suffering from heat stress. Its ability to tolerate both extreme cold and intense sun makes it a great choice for xeric landscapes, where water conservation is a priority.
One of the standout features of Alcalde Cold Hardy rosemary is its pale blue flowers. These delicate blooms add a touch of color to the garden, creating a visually appealing contrast against the plant’s thick, olive-green leaves. The combination of the soft blue flowers and the vibrant green foliage creates a beautiful and eye-catching display.
In terms of its physical characteristics, Alcalde Cold Hardy rosemary has an upright growth habit. This means that it tends to grow vertically, rather than spreading out horizontally. This can make it a great choice for smaller gardens or for those looking to create a vertical accent in their landscaping.
From personal experience, I have found Alcalde Cold Hardy rosemary to be a reliable and resilient plant. I have seen it thrive in a garden that experiences harsh winters with sub-zero temperatures. Despite the freezing temperatures, the rosemary has continued to grow and flourish, providing a beautiful addition to the landscape.
