Etymology
The generic name "Kleinia" (pronounced "KLINE-ee-uh") honors Jacob Theodor Klein (1685-1759), also known as Plinius Gedanensium, a German jurist, historian, botanist, zoologist, mathematician, and diplomat in the service of Polish King August II the Strong.
The specific epithet "fulgens" (pronounced "FUL-jenz") means "shining, glittering" and refers to the vibrant scarlet color of the flowers of this species.
Description of Kleinia fulgens
Kleinia fulgens, also known as Senecio fulgens, is a small succulent plant with creeping rootstock and erect or ascending, cylindrical stems, which are brittle and bear succulent leaves. It can grow up to 2 feet (60 cm) tall and typically branches near the base, where it is also most leafy. The leaves are glaucous green, inversely lance-shaped, and have margins that are either entire or coarsely and irregularly toothed in the expanded part. They can measure up to 4.8 inches (12 cm) long and 1.4 inches (3.5 cm) wide.
From late fall to mid-winter, Kleinia fulgens produces attractive flower heads comprised of densely crowded, scarlet florets, which can sometimes be orange-scarlet or almost crimson. The flower heads can reach 1 inch (2.5 cm) in length and 1.2 inches (3 cm) in diameter, and usually appear in loose terminal clusters or, rarely, solitary on long stalks.
Origin of Kleinia fulgens
Kleinia fulgens is native to the Democratic Republic of Congo, Angola, Zambia, Zimbabwe, Mozambique, Eswatini, and South Africa. It grows in valley woodland and scrub, mainly on rocky ledges of cliffs and steep rocky slopes at elevations between 3,540 and 4,265 feet (1,080 and 1,300 m).
How to Grow and Care for Kleinia galpinii
Light: Kleinia fulgens thrives in bright, indirect sunlight or light dappled shade. It can tolerate early morning sun but should be protected from harsh midday sun during the summer to prevent leaf scorching. Indoors, a window with filtered light is ideal.
Soil: Well-draining soil is essential for the healthy growth of this succulent. Use a commercial potting mix designed for succulents, or make your own.
Temperature: Like most succulents, Kleinia fulgens is well-adapted to tolerate drought and heat but does not tolerate cold temperatures very well. It is hardy in USDA Plant Hardiness Zones 10a-11b, which have average annual extreme minimum winter temperatures ranging from 20°F to 50°F (-1.1°C to 10°C).
Watering: During the growing season, water the plant thoroughly and then allow the soil to dry completely before watering again. In winter, when the plant becomes somewhat dormant, reduce watering significantly.
Fertilizing: Be cautious with fertilization, as excessive amounts can lead to leggy growth. Feed with a dilute solution of a balanced, water-soluble fertilizer only during the growing season.
Repotting: This plant does not require frequent repotting. Repot every 2 to 3 years or when the plant becomes root-bound. When repotting, choose a pot that is only slightly larger and ensure it has drainage holes.
Propagation: Kleinia fulgens can be easily propagated from stem cuttings during the growing season. It can also be propagated from seed when available. The best time to take cuttings and sow seeds is in late spring and early summer.
