Plectranthus argentatus (Silver Plectranthus) is a bushy or semi-trailing perennial native to Australia. This plant can easily make a stunning specimen in any garden, with its large felted silver leaves and candelabras of coleus-like flowers, in colors such as white, off-white, shades of blue, lavender, and purple. Not only are the blooms beautiful, but they also release a fragrance that can be likened to spices or herbs.

To thrive, Silver Plectranthus does best when planted in full sun or semi-shade, and requires regular or moderate watering, depending on the climate. The plant is hardy to USDA zones 9-11, so it can be grown outdoors if the climate permits it. Colder zones can also support Silver Plectranthus by growing them in decorative containers and ensuring a regular watering routine with good quality potting soil, but avoid overwatering. The soil should be kept moist, yet drainable, and pruning is recommended if the growth becomes too leggy. To maintain a container plant, it should be given a quality fertilizer and repotted every two years, as well as deadheaded and protected from frost.

Regardless of the climate, Silver Plectranthus is a robust, low maintenance plant that is relatively unstressed by pests and disease. Its showy foliage, vibrant blooms, and fragrant scent make it an essential feature in any garden. It is the perfect drought-tolerant plant that will make a captivating addition to any outdoor area!
