Karoo White Nemesia

Karoo White Nemesia (Nemesia fruticans 'Karoo White') is a pristine, elegant cool-season perennial annual producing an abundance of pure white blooms with a bright golden-yellow eye that creates a crisp, clean, luminous display with timeless sophistication in any container, mixed border planting, or cottage garden setting. The Karoo fruticans series is celebrated for its superior perennial vigor, extended bloom season, and outstanding cool-season performance, with Karoo White delivering its most prolific and beautiful display during the moderate temperatures of late winter, spring, and fall — where its pure white blooms glow with exceptional brightness and pair harmoniously with virtually every companion plant color palette imaginable.

Grown from our premium organic heritage program, each plant ships with a Professional Grade root system — dense, well-branched, and ready for vigorous, immediate establishment. Karoo White thrives in full sun to part shade with consistent moisture and is an exceptionally versatile companion plant, combining beautifully with virtually any color scheme from bold, high-contrast pairings with deep purples and rich blues to soft, romantic pairings with blush pinks, creamy yellows, and soft lavenders throughout the cool growing season. Its naturally spreading, well-branched habit and clean, versatile white blooms make it an essential foundational plant in any cool-season organic container garden or mixed border planting.

• Pristine Pure White Blooms with Gold Eye — Crisp, clean pure white petals with a bright golden-yellow eye create a luminous, timeless display that pairs harmoniously with virtually every companion plant color palette in mixed containers and garden borders.
• Fruticans Perennial Series Vigor — Nemesia fruticans genetics deliver superior perennial vigor, extended bloom season, and outstanding cool-season performance compared to annual nemesia — often reblooming through summer in mild coastal and Mediterranean-climate gardens.
• Outstanding Cool-Season Performer — Blooms most prolifically in the moderate temperatures of late winter, spring, and fall, making Karoo White an essential foundational plant for cool-season containers, mixed borders, and cottage garden arrangements.
• Exceptionally Versatile Companion Plant — Pure white blooms complement every companion plant color palette imaginable — outstanding with deep purples, bold blues, rich pinks, warm yellows, and soft lavenders in mixed cool-season container and border designs.
• Early Spring Pollinator Support — Pure white blooms with golden-yellow eyes attract native bees and beneficial insects during the critical early spring foraging season when cool-weather pollinator food sources are most limited and ecologically valuable.

These 4" healthy live plants thrive in full sun to part shade with consistent moisture — water when the top inch of soil is dry and apply a balanced liquid fertilizer every two weeks to sustain prolific cool-season blooming. Karoo White is a tender perennial grown as a cool-season annual in most climates, with potential for extended perennial performance in USDA zones 9–11; plant in early spring for late winter through late spring color, or in late summer for a crisp, clean fall display. Trim lightly after the main bloom flush to encourage a vigorous fresh second wave of pristine white blooms through the season.
