Syringa is a genus of 12 currently recognized species of flowering woody plants in the olive family called lilacs. They are small trees or shrubs ranging from 2 to 10 metres tall, native to woodland and scrub from southeastern Europe to eastern Asia, and widely cultivated in temperate areas. Lilacs produce flowers in spring in shades of purple, white, pale yellow, pink, or dark burgundy, growing in large panicles.
Water: Medium · Height: 300 cm · Soil: Suitable for light (sandy), medium (loamy) and heavy (clay) soils; prefers well-drained soil and can grow in heavy clay soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils and can grow in very alkaline soils.
lilac is usually grown from cuttings rather than seed. Take a healthy stem cutting, remove the lower leaves, and root it in moist, free-draining compost.
