Take the generous, ever-blooming charm of the Blue Potato Bush and put it on a single stem—you get something truly special. The Blue Potato Bush Standard Tree features a clean, upright stem topped with a rounded, lollipop-shaped canopy of slender, arching branches clothed in small, oval, medium-green leaves. From spring through autumn (and often year-round in mild coastal gardens), it produces an abundance of trumpet-shaped flowers in striking bright blue-purple, each with a prominent, star-shaped golden-yellow eye. Small, ornamental, orange-red berries sometimes follow, adding further interest.
Native to South America (Argentina, Bolivia, Brazil, and Paraguay), this adaptable plant thrives in South African gardens. In the Western Cape, it needs full sun—at least 6 hours of direct light daily for the most abundant blooms and a dense, compact canopy. It adapts to most well-drained soils, from sandy to loamy, and once established, is remarkably drought-tolerant, though it flowers best with regular water. It tolerates cold and light frost, but in colder inland valleys, the standard form is best grown in a movable container. With a canopy reaching 80–120cm wide atop an 80–120cm stem, it’s perfect for framing doorways, flanking pathways, or adding vertical accent to patios and small gardens.
Key Features:
- Artfully trained standard form with a single stem and rounded, lollipop-shaped canopy
- Masses of violet-blue flowers with sunny yellow centres from spring through autumn
- Nectar-rich blooms irresistible to bees and butterflies
- Ideal for large pots, urns, patios, balconies, and small gardens
Gardening Note: Plant in full sun in well-drained soil. A sturdy stake is essential to keep the standard form straight and upright. Water regularly until established; mature plants are drought-tolerant but flower best with regular water during the growing season. Prune the canopy heavily after each major flowering flush to maintain its rounded shape and encourage continuous blooms. Remove any shoots that emerge from the main stem below the canopy. Tolerates light frost; in colder inland areas, grow in a movable container to shelter during winter.
