Plumbago auriculata, commonly known as Blue Plumbago, is native to South Africa, the Himalayas, and China and can be found in tropical and sub-tropical gardens where it is used to create beautiful hedges or low shrubs due to its ability to withstand a variety of conditions. It grows best in full sun and reaches a height of 5-10 feet, however when planted in less sunny climates it can be kept as a semi-shrubby evergreen and kept at a height of 2-5 feet.
Plumbago can handle drought and poor soil conditions, but in areas with heavy rainfall its foliage and flowers may become crushed so it's best suited to slightly higher altitudes. Pruning is key to its success as it needs to be cut back to the ground at least once a year to maintain its healthy growth. Propagation is done through green cuttings or dividing of its roots.
Not only are the delicate lavender-purple or blue flowers of Plumbago aesthetically pleasing but it offers a wide range of benefits for pollinators like hummingbirds, butterflies, and beneficial insects. Additionally, it is known for its salt-tolerance, making it an excellent choice for seaside gardens.
For gardeners living in cooler climates, Plumbago is easily kept inside in a container as it is a suitable houseplant. For best results, keep the soil moist and make sure the container is appropriately aerated. During colder months, bring the container inside and place it in the sunniest window in the home. Additionally, be sure to check up on the soil periodically as it can be overly saturated during the spring or overly dry during winter. Give your plant the occasional fertilizing session to keep it healthy and well-nourished.
