Convolvulus tricolor ‘Minor White Ensign’ is a compact, low-growing annual known for its crisp, tricolour blooms and neat trailing habit.

It’s a dwarf form of Convolvulus tricolor, often used in rock gardens, edging, and containers.

Key features

• Flowers: white trumpet-shaped blooms with a yellow throat and subtle blue/purple banding (“flag” pattern)
• Growth habit: compact and spreading, usually 15–25 cm tall
• Bloom time: late spring through summer (long flowering if deadheaded)
• Light: full sun (best flowering and tight growth)
• Soil: well-drained, even poor or sandy soils
• Use: borders, containers, hanging baskets, gravel gardens

Despite the name, it’s not related to true bindweed vines that are invasive—this is a tidy ornamental cultivar.
