Cape honeysuckle comes in a blazing orange color that is sure to brighten up your tropical garden. It is used as either a shrub or liana. Due to its color and sweet nectar, it attracts hummingbirds. Not only is it versatile in looks but it also is quite easy to maintain, which makes it a perfect idea for a splash of uniqueness in your garden.
The name cape honeysuckle came about because the native region for this shrub is in South Africa by the Cape of Good Hope. It is a bit misleading as this is not true honeysuckle. Real honeysuckles belong to the Caprifoliaceae family and are found in the Lonicera genus. Other members include the desert willow, northern and southern catalpa, and jacaranda.

How to Grow Cape Honeysuckle
The shape of this plant depends entirely on how you let it grow, as it can either be a shrub or vine. As a shrub, it can be anywhere from 3-10' tall, depending on how consistently you prune it. In vine form it will travel a lot farther, reaching lengths of 25-30' or more. Usually, the cape honeysuckle is treated as a shrub and clipped into a box shape. However, this plant also likes to vine, so consider it for your trellis or pergola.
Each pinnately compound leaf is made up of 5-9 leaflets that are shaped like diamonds. Whether they are evergreen or deciduous depends on how cool the climate gets in winter.
During the fall through spring (possibly the entire year), the cape honeysuckle will be covered with an abundance of orange (sometimes reddish or yellow, depending on variety) blooms in the shape of a trumpet. Once the flowers have been pollinated, long capsule fruits are produced.
Pruning depends on the shape you've chosen. If you're going for a hedge, trimming may be required on a regular basis since this grows fast. Cut it back to the ground every 3-4 years in the spring(or as needed) to help keep it from sprawling. You should also prune away branches that were damaged by frost at the start of spring.
This plant does produce suckers. Clip them away if you don't want them to spread. Less maintenance will be needed if you're using it like a vine. You will just need to keep it trained on its support system.
There aren't many problems with this plant. If your zone gets some frost, this can cause damage to the leaves and branches. You may run across problems with too little or too many nutrients, which is usually most apparent in the foliage. There may be other environmental problems like leaf scorch. Overall, though, this shrub should stay happy and healthy over its lifetime with little maintenance.
Cape honeysuckle is a tropical plant and does prefer full sun. Some light shade, however, is acceptable, though shaded plants will produce fewer blooms.
Don't fret about the pH of your soil too much, as this plant can handle both acidic and alkaline soils. It also grows in salty locations like coastal regions and can handle gusts of wind.
Water your cape honeysuckle weekly if you are growing it in full sun, or just once or twice a month if it is in shade. After a year or regular watering, the roots should be established enough to provide drought tolerance.
Temperature and Humidity
Cape honeysuckle is a tropical plant that thrives in hardiness zones 9–11. It is heat and drought tolerant, but its branches and leaves tend to die back at temperatures under 25 degrees Fahrenheit.
If you've tested the soil and detected a lack of nutrients, go ahead and use some fertilizer. It is usually not needed, though. It is a good idea to mulch your cape honeysuckle if there is a predicted frost.
Varieties of Cape Honeysuckle
