French Lilac – ‘Dark Koster’
The French Lilac – ‘Dark Koster’ (Syringa vulgaris – ‘Dark Koster’) is a large flowering, deciduous shrub in the Oleaceae family of olives. It is a cultivar originating from the Common Lilac.
It is native to eastern Europe.
It grows to about 6 metres (20 feet) tall into a leggy, irregular-shaped thicket due to its secondary shoots from the base. It has grey bark and 20 centimetre (8 inch) wide stems.
Its green, oval to heart-shaped leaves are 4-12 centimetres (2-5 inches) long and 3-8 centimetres (1-3 inches) wide.
The single, tubular lilac flowers are arranged in dense panicles about 8-18 centimetres (3-7 inches) long.
The fruit is a brown capsule, 1-2 centimetres (less than an inch) long, splitting in two to release the two-winged seeds.
The French Lilac – ‘Dark Koster’ blooms from late spring to early summer.
