Grace Ward Lithodora
Lithodora diffusa ‘Grace Ward’Grace Ward Lithodora is a low-growing evergreen perennial prized for its intense blue flowers, dense spreading habit, and year-round foliage. Blooming heavily in mid to late spring with sporadic rebloom throughout summer, it produces masses of brilliant sapphire-blue, star-shaped flowers that nearly cover the foliage. The vivid blooms create a striking contrast against the narrow, deep green leaves, making this one of the most eye-catching groundcovers for sunny landscapes.
Its compact, mat-forming habit makes it an excellent choice for rock gardens, slopes, edging, and spilling over retaining walls. The evergreen foliage provides attractive texture throughout the year, while the brilliant flowers add exceptional seasonal color. Its slow, controlled spread allows it to fill spaces without becoming invasive.
Typically reaching just 4 to 8 inches tall while spreading 18 to 24 inches wide, Grace Ward Lithodora is ideal for small gardens, borders, and containers. Its low-growing nature makes it especially effective for softening hardscape edges and suppressing weeds.
This perennial thrives in full sun to partial sun and prefers acidic, well-drained soil. Once established, it tolerates short periods of drought but performs best with consistent moisture and excellent drainage. Avoid heavy clay soils or areas that remain wet during winter.
Care Instructions:
Planting: Plant in full sun to partial sun in a location with excellent drainage.
Soil: Prefers organically rich, acidic, well-drained soil.
Watering: Water regularly during establishment. Keep the soil evenly moist but never saturated.
Fertilizing: Apply an acid-loving plant fertilizer in early spring if needed.
Pruning: Lightly trim after flowering to maintain a neat shape and encourage dense growth.
Spacing: Space plants 18–24 inches apart for mature spread.
Maintenance: Avoid poorly drained soils and mulch lightly to help retain moisture while keeping the crown dry.
Its brilliant blue flowers, evergreen foliage, and spreading habit make Grace Ward Lithodora an outstanding groundcover for adding long-lasting color and texture to the landscape.
