Asiatic Jasmine, also known as Trachelospermum asiaticum, is a popular choice for groundcover due to its vining growth habit. However, it is important to note that Asiatic Jasmine may turn brown in extended freezing temperatures. This is because it is not frost tolerant and can be damaged or killed by severe cold.
In my personal experience as a gardener and landscaper, I have seen Asiatic Jasmine suffer damage from freezing temperatures. In areas with mild winters, where freezing temperatures are infrequent or short-lived, Asiatic Jasmine may fare better and only experience minimal browning. However, in regions with harsh winters and prolonged freezing temperatures, Asiatic Jasmine may struggle to survive.
To protect Asiatic Jasmine from freezing, there are a few steps you can take. Firstly, consider planting it in areas that are sheltered from cold winds and exposed to sunlight. This can help create a microclimate that is slightly warmer and less prone to freezing. Additionally, adding a layer of mulch around the plants can provide some insulation and protect the roots from extreme cold.
If you live in an area with particularly cold winters, you may want to consider using Asiatic Jasmine as an annual groundcover or opting for more cold-hardy alternatives. There are several other groundcover options, such as creeping thyme or sedum, that are better suited to withstand freezing temperatures.
It is also worth mentioning that Asiatic Jasmine has a reputation for its aggressive growth. This can make it challenging to grow companion plants next to it, as the Jasmine may outcompete and overshadow them. If you do choose to plant other species alongside Asiatic Jasmine, regular pruning or mowing can help keep it in check and prevent it from taking over the entire area. Trimming or mowing the Jasmine one to two times a year can help maintain its compact growth and prevent it from becoming too invasive.
While Asiatic Jasmine is a popular choice for groundcover due to its vining growth and attractive foliage, it is not frost tolerant and may turn brown in extended freezing temperatures. If you live in an area with cold winters, you may want to consider using it as an annual groundcover or exploring other cold-hardy alternatives. Additionally, its aggressive growth may pose challenges when trying to grow companion plants, but regular pruning or mowing can help keep it in check.
