Ceanothus thyrsiflorus, known as blueblossom or blue blossom ceanothus, is an evergreen shrub in the genus Ceanothus that is endemic to California. The term 'Californian lilac' is also applied to this and other varieties of ceanothus, though it is not closely related to Syringa, the true lilac.
Description
C. thyrsiflorus can grow more than 6 m (20 ft) tall in its native chaparral habitat. Flowers vary from different shades of blue to close to white. It is popular with birds, butterflies, and other pollinators.
Cultivation
C. thyrsiflorus has been used in gardens extensively, and several cultivars have been selected. Popular garden varieties include:-
- 'Blue Mound' which can grow to 1.5 m (4 ft 11 in) tall
- 'Cascade' which may reach 8 m (26 ft) of height
- 'El Dorado', a variegated cultivar with gold edge foliage and powder blue flowers[1]
- 'Repens' which stays as a shrub around 1–3 m (3 ft 3 in – 9 ft 10 in) tall
- 'Repens Victoria', forming a sturdy evergreen mound and most useful groundcover with powder blue flowers
