Gorgeous bi-color stars! The Blue Star Lithodora (Lithodora diffusa 'Blue Star') forms thick carpets of vivid green, fine-textured foliage that smothers itself in blue and white star-shaped blossoms from late spring until early summer!
Low maintenance and Xeric, weed-blocking, this is a fantastic groundcover for carpeting your gardens bare spots with vibrant color and durable beauty! Handling light foot traffic, and softening hard corners of walls or the edges of garden borders.
Blue Star features brilliant white blossoms with a distinct bright blue stripe down the center of each petal! Butterflies and bees adore these flowers and both arrive in swarms! In full sun, the bright green foliage can barely be seen through all the flowers!
Planting and Application:
Lithodora are fantastic planted as erosion control atop steep slopes and hard-to-mow hillsides. Partly evergreen in mild winters, you’ll enjoy year-round groundcover in hardiness zones 6 and up. Let spill over retaining walls or ramble through the cracks and crevices of rock walls, or creep through your Rock garden for a gorgeous effect!
Blue Star Lithodora is ideal edging to soften the transition between lawn and garden edges and is durable enough for that tricky location along the roadside. Let spill and cascade over the edges of pots on your sunny front porch, or as filler in large mixed patio planters! These are even tough enough for along driveways, paths and between pavers where light foot traffic won’t slow them down!
- Bright Blue & White Star-Shaped Flowers
- Low-Growing Bright Green Foliage
- Dense Carpet-Forming Clumps
- Xeric & Butterfly-Friendly
- Containers, Rock Gardens, Erosion Control & Groundcover
#ProPlantTips for Care:
Lithodora flowers best in full sun, handling part shade, but you’ll have fewer flowers. These need very well-drained, slightly acidic soil. Shear lightly after flowering in late summer to retain the dense form. These Xeriscaping perennials may even winter over in zone 5 if covered with evergreen boughs and mulch.
- Full Sun & Part Shade - Fewer Blooms
- Sharply-Draining Acidic Soil
- Low to Average Moisture
- Low-Maintenance
- Shear After Flowering
