PARAHEBE Avalanche

Description and Characteristics

Parahebe ‘Avalanche’ is a charming evergreen, mat-forming perennial known for its delicate appearance and vigorous ground-covering habit. It produces masses of small, white, four-petaled flowers, often with subtle lilac or purple veining, blooming in waves from late spring to early autumn. These dainty flowers contrast beautifully with the plant’s tiny, glossy, dark green leaves, which form a dense, low-growing carpet.

Parahebe ‘Avalanche’ typically grows to about 15–25 cm in height with a spread of 60–90 cm, making it an excellent choice for edging paths, filling gaps in rockeries, or spilling over walls and containers. Despite its delicate look, this variety is hardy and resilient, thriving in sunny, well-drained locations and tolerating light frost.

It is a member of the Plantaginaceae family, and closely related to veronicas. In colder areas, it may be semi-evergreen, but will regrow quickly in spring.
