Cold Hardy Landscape Cacti & Succulents for Central Texas Jeff Pavlat 6/10

The following is a list of recommended landscape plants for Central Texas. Keep in mind that there is a great deal of temperature variation across the region. Temperatures in outlying areas are in some cases 10 to 15 degrees colder than those in town. The cold tolerances listed are approximate.

It is important to recognize that there are a number of factors which determine hardiness. Plants placed on south facing slopes receive more solar heat and tend to have a better chance of being undamaged. Plants also fair better with some overhead protection from a tree or shrub. It also helps for them to be placed where they will not receive direct north wind. Generally, low-growing plants receive more ground heat than taller plants and are less likely to freeze. The state of the plant as it enters freezing temperatures is an important factor as well. For instance, many cacti and succulents will endure considerably colder temperatures when dry rather than wet (In fact, cold and wet is often a lethal combination for many cacti). Plants of the same species originating from different parts of the plant’s native range can also result in higher or lower tolerances. It is possible to have two plants of the same species placed side by side and have one freeze, while the other survives. Often some experimentation is necessary to determine what plants will work best for your garden.
