Leucophyllum x 'Heavenly Cloud'

(Heavenly Cloud Texas Ranger)

Leucophyllum x ‘Heavenly Cloud’ (Heavenly Cloud Texas Ranger) is a dense, upright, mostly evergreen shrub that reaches an average mature landscape size of 6–8′ tall by 5–6′ wide. Small gray-green leaves cover upright branches, and masses of purple flowers appear in flushes from spring through fall. A tough, fast-growing choice for full sun, it makes an excellent hedge, screen, or backdrop for a deep border.

Other common names this variety is known by also include Texas Sage, Cenizo, and Barometer Bush.

Origins And Landscape Adaptability

The genus Leucophyllum is native to northern Mexico and Texas. ‘Heavenly Cloud’ is a nursery hybrid of the selection ‘Green Cloud’ (Leucophyllum frutescens) and Chihuahuan sage (Leucophyllum laevigatum). In Texas, Leucophyllum is known as Barometer Bush for its habit of bursting into bloom when humidity rises or summer rain arrives. ‘Heavenly Cloud’ is one of the earliest Texas Rangers to flower.

Rated for USDA zones 8–11 and Sunset Garden Zones 8–24, H1 and H2. Thrives in heat and reflected heat from walls and pavement, which makes it a good choice for California’s warm inland valleys. Hardy to about 10°F.

Planting And Care Instructions

Sunlight: Full sun exposure. Reflected heat is fine.

Watering: Water regularly after planting to help it establish in its new location, then reduce frequency. Once established, this variety is very drought tolerant and does best with long dry periods between waterings. Overwatering is the most common cause of decline.

Soil: Plant in lean, well-draining soil. It tolerates a range of soil types as long as water does not stand around the roots. In heavy clay, plant on a mound or slope, or amend with sand or gravel to improve drainage.

Fertilizing: Fertilizing is not required. A light application of general fertilizer in spring before new growth begins is enough.

Pruning: Minimal pruning is needed. Prune lightly after flowering to maintain fullness, or shear for a more formal hedge.

USDA Hardiness Zones: Rated for USDA growing zones 8–11. Hardy to about 10°F.

Pollinators: The flowers attract bees and butterflies.

Landscape Design Ideas

Plant Heavenly Cloud in multiples as a hedge or screen, along a sunny fence line, or against a hot wall. It also adds height at the back of a deep border and looks natural in loose, low-care designs. The mounding, upright form suits foundations and large pathways, and the foliage stays fine-textured and soft-looking between bloom cycles.

Plant it alongside other sun loving varieties such as Hesperaloe parviflora, whose arching rose-red flower stalks contrast with the shrub’s purple blooms. For a cooler, fragrant palette, use Lavandula intermedia ‘Phenomenal’ at the front of the planting.
