The specific epithet "bolusiana" (pronounced "bol-oo-see-AY-nuh") honors Harry Bolus (1834-1911), a South African botanist, botanical artist, businessman, and philanthropist.
Origin
Ipomoea bolusiana is native to Madagascar and South Africa.
Description
Ipomoea bolusiana is a small caudiciform plant with a thick, tuberous rootstock and one or several erect or prostrate stems with green, widely spaced leaves. The caudex can reach a diameter of 8 inches (20 cm). The stems are slender, hairless, woody at the base, and can grow up to 10 feet (3 m) long. The narrow leaves can measure up to 2.8 inches (7 cm) long.
The flowers are mauve or magenta-pink, darker in the centers. They are funnel-shaped, appear near the base of the stem from spring to fall, and can reach a length of up to 2.8 inches (7 cm).

Hardiness
USDA hardiness zones 10b to 11b: from 35°F (1.7°C) to 45°F (7.2°C).
How to Grow and Care
Most species have spectacular, colorful flowers and are often grown as ornamentals, and many cultivars have been developed. Ipomoeas need full sun and moderately fertile, well-drained soil in the garden. Provide shelter from the wind. Prune climbing species in spring. Under glass, provide full light with protection from the hottest sun. Water the plant freely and fertilize monthly during the growing season, but water sparingly in winter. Climbers and trailing species need support.
Chip seeds with a knife, scrape with sandpaper, or soak in water for 24 hours before sowing at 64°F (18°C) in spring. Root softwood cuttings of perennials or shrubs in spring or summer, or take semi-ripe cuttings in summer.
White blister, rust, fungal leaf spots, stem rot, thread blight, charcoal rot, and wilt can occur.
