![]() ![]() If you do not know your zone you can find it by clicking on the " USDA Cold Hardiness Zones" link here or above. For more on stretching your cold hardiness zones see the " "Growing on the Edge Growing Guide". Our zones do not always agree but we try to use our own experience as to what can be depended on to return or have known reputable gardens and or horticulturists to reliably grow that plant in zones that are usually colder but sometimes warmer than what other resources have available. Each zone is separated by 10 oF and the map was updated in 2012. And these are averages, here in zone 8B ('A' represents the colder half of a zone and 'B' represents the warmer half of the zone and they are separated by about 5 oF) we have seen single digits but that is the exception but should be noted by the daring gardener. USDA Cold Hardiness Zones were established to give gardeners, horticulturists, farmers, nurseries, and landscape architects a universal way to describe where a plant will survive with regard to average winter lows for a region. Under poor growing conditions plants may be slightly to significantly smaller, whereas excellent growing conditions can produce larger more vigorous plants. Parentheses are used to indicate that the plant can potentially reach that dimension, although the sizes outside of the parentheses tend to be more typical. Feet are represented by a single quote and inches by a double quote. This is the average expected mature height by width in feet or inches. Jacob's Ladder is known to be pollinated by visiting Hummingbirds. It is tolerant of mild frosts and may return from the base if frozen to the ground. For best results provide the Devil's Backbone with a fast draining cactus-like soil and full to partial sun out of doors. We were pleasantly surprised to learn that this unusual plant is also a US native plant found growing naturally in the southern most portion of Florida with its main range being the warmer portions of central and south America. The Red Bird Cactus is not a true cactus at all but is not classified as a Euphorbia but is certainly as easy to grow as most Cacti. This is an easy and forgiving succulent that develops into an architecturally pleasing specimen plant suitable for a semi-shaded porch or patio and it tends to have more pink foliage coloration where it receives some direct sunlight as well as during cooler weather. Allow the soil to become somewhat dry between waterings although it can tolerant more moisture when in active growth and less during winter. The beautifully variegated foliage of this Red Bird Cactus, actually a Euphorbia or Pedilanthus and not a true cacti, makes this plant worth growing although the plant gets it's name from the clusters of tiny red bird-shaped that may be produced in summer.
