Philadelphus ‘Avalanche’ (Mock Orange)
Mock Orange 'Avalanche', Philadelphus lemoinei 'Avalanche'
Regarded as one of the most fragrant of all Mock Oranges, Philadelphus ‘Avalanche’ is a multi-stemmed deciduous shrub of great beauty when in bloom. In late spring to early summer, its pleasantly arching branches bear clusters of cup-shaped, 4-petaled, white flowers, 1 in. across (2.5 cm), at their tips. The blossoms stand out against the foliage of oval, dark green leaves. Introduced in 1896, ‘Avalanche’ is a lovely flowering shrub that deserves a spot where its fragrance can be enjoyed.
- Grows with an upright, arching habit to 4-5 ft. tall (120-150 cm) and 5-10 ft. wide (150-300 cm).
- A full sun to light shade lover, this plant is best grown in average, medium moisture, well-drained soils. This plant is not fussy about soils as long as they have good drainage. Drought tolerant.
- Generally pest and disease free. Watch for leaf spot, canker, powdery mildew and rust.
- Great for shrub borders, foundation plantings, and informal flowering hedges.
- Blooms on previous year’s wood, so prune immediately after flowering. May be cut to the ground to rejuvenate this shrub.
- Propagate by softwood or hardwood cuttings
