— Westringia fruticosa ‘WES06’ Low Horizon™ PPAF —
Our smallest groundcover form of coastal rosemary. Best suited to Zones 9-11 in arid climates although shows potential for low water gardens in humid regions. Selected from our already-diminutive variety we call “Mundi”, Low Horizon has essentially the same habit and color only in a dwarfed package, reaching only about two-thirds the size of the parent. Flowers are very similar to Mundi: small (simple), bright white flowers arranged in small clusters appear in spring and summer. We have introduced a few Westringia selections that will thrive in humid/subtropic climates, and we are gaining confidence that Low Horizon may also fit into this category. That said, all Westringia are best suited to Mediterranean climates in Zones 9-11.
- Very low-growing, prostrate and dense growth habit
- Ideal groundcover for low-water mass plantings
- Masses of small, white flowers in spring
Life Cycle: Evergreen
Hardiness Zones: 9 to 11; decent frost tolerance but will show some injury under severe conditions of prolonged cold and heavy frost (relative to Zone 9) so better suited to Zone 9b and warmer.
H x W (approx): Approx 1ft tall and 4 ft wide after several years; responds well to pruning, if needed.
Spacing: 3ft on center for mass plantings
Bloom Time: Spring to summer
Flower: Small white flowers appear in clusters along the stems from spring and into summer
Foliage Color: Young growth is light gray-green; matures to a dark gray-green with a smooth texture
Habit: Prostrate, compact and dense
Containers?: Yes. Same/similar applications as our Westringia Mundi (rosemary-like
leaves add texture, spring flowers add a pop of white and the plant will trail over the
sides planters and mixed containers)
Light Requirement: Full to filtered sun
Water Requirement: Very drought tolerant once established
Maintenance Category: Low Maintenance; salt tolerant, drought tolerant
Uses: Drought tolerant mass and group plantings or as an accent; coastal, salt laden
landscapes; water-wise gardens
Maintenance Notes: Looks it best in full sun with deep, infrequent irrigation in the
southeast and slightly more “regular” irrigation in arid climates. Responds well to pruning.
