Cape Honeysuckle, also known as Tecoma capensis, is a beautiful and vibrant flowering plant that is commonly grown in gardens and landscapes. However, one important factor to consider when growing Cape Honeysuckle is its ability to survive winter.
Cape Honeysuckle is generally considered to be winter hardy in USDA zones 9-11. This means that it can withstand the colder temperatures typically experienced in these regions. However, it is important to note that even within these zones, there can be variations in temperature and weather conditions that may impact the plant’s ability to survive winter.
When it comes to colder temperatures, Cape Honeysuckle has its limits. The plant can tolerate temperatures down to about 25 degrees Fahrenheit (-4 degrees Celsius). Anything lower than this can cause the leaves and branches to die back. Therefore, if you live in an area where temperatures regularly drop below 25 degrees Fahrenheit, it is unlikely that Cape Honeysuckle will survive the winter without some form of protection.
To provide some context and personal experience, I live in USDA zone 9b where winter temperatures rarely dip below 30 degrees Fahrenheit. In my garden, Cape Honeysuckle has been able to withstand the winter without any issues. However, during particularly cold snaps, I have noticed some leaf damage and dieback. Nonetheless, the plant has always managed to bounce back and thrive once the warmer temperatures return in spring.
If you live in a colder climate outside of USDA zones 9-11, you have a few options to help Cape Honeysuckle survive the winter. One approach is to grow it as a container plant that can be brought indoors during the colder months. This allows you to control the temperature and protect the plant from freezing temperatures.
Another option is to provide some form of winter protection for the plant if you prefer to grow it in the ground. This can be done by applying a thick layer of mulch around the base of the plant to insulate the roots and protect them from freezing. Additionally, you can cover the plant with a frost cloth or burlap to provide extra protection from cold winds and frost.
It is worth noting that while Cape Honeysuckle can survive winter, it may not flower as profusely during this time. The colder temperatures can inhibit flower production, and the plant may go into a dormant state until warmer weather returns. However, once spring arrives, Cape Honeysuckle will typically bounce back and resume its vibrant blooms.
While Cape Honeysuckle is generally winter hardy in USDA zones 9-11, it may not survive colder temperatures below 25 degrees Fahrenheit. If you live in a colder climate, consider growing it as a container plant or provide winter protection to help it survive. Personal experiences may vary, but with proper care and attention, Cape Honeysuckle can continue to thrive and bring beauty to your garden.
