Description
The Ceanothus ‘Blue Sapphire’, commonly known as California Lilac, is a stunning evergreen shrub celebrated for its vibrant, cobalt-blue flowers and compact growth habit. Blooming prolifically in late winter and spring, its dense clusters of tiny, deep blue flowers contrast beautifully with the plant’s dark green, glossy foliage, which has a slight bronze tinge in new growth. Growing to about 1 meter tall and 1.5 meters wide, this low-maintenance shrub is ideal for small gardens, borders, or rockeries.
Climate Suitability:
‘Blue Sapphire’ thrives in Australia’s temperate and coastal climates, particularly in regions with well-drained soils. It is drought-tolerant once established, making it a fantastic choice for waterwise and Mediterranean-style gardens. It prefers protection from heavy frost in cooler regions.
Soil and Watering:
This Ceanothus thrives in sandy, loamy, or rocky soils with excellent drainage. Avoid heavy clay soils that retain water. Water deeply but infrequently during prolonged dry spells. Overwatering should be avoided, as it can lead to root rot.
Care Tips:
- Plant in a position with full sun to light shade for the best flowering display.
- Avoid excessive pruning; lightly trim after flowering to maintain shape and remove spent blooms.
- Mulch around the base to suppress weeds and retain soil moisture, ensuring the mulch doesn’t touch the trunk.
- Fertilization is rarely needed but can be applied sparingly in early spring for a nutrient boost.
Uses in Landscaping:
‘Blue Sapphire’ is a versatile and striking addition to Australian gardens. It works beautifully as a low hedge, ground cover, or feature shrub. Its brilliant blue flowers attract bees and butterflies, enhancing biodiversity while adding a splash of vibrant color to any sunny space.
