Variety traits
Syringa vulgaris L.
The height of a lilac bush is a key varietal trait for DUS testing, determined in mature plants aged 4–5 years. The index ranges from dwarf forms to 7 meters in species specimens.
In the reference 3 varieties crop Common lilac, where this is mentioned in the description.
To assess the varietal characteristics of Syringa vulgaris, bush height is measured in mature plants, which is necessary for conducting tests for distinctness, uniformity, and stability. The classification adopted in practice divides varieties into dwarf (0.9–1.2 m), medium-sized (1.2–2.4 m), and tall (3–5 m), although in natural conditions without formative pruning, the shrub is capable of reaching 6–7 meters.
The growth rate of lilacs is characterized by a moderate annual increment of about 20–30 cm, and reaching the varietal height takes from 10 to 20 years. Agrotechnical management of the habit is carried out through pruning of skeletal branches to restrain vertical growth and maintain the decorative compactness of the bush.
