📌 Note: Syringa vulgaris is a deciduous shrub, and the appearance of its foliage naturally varies depending on the season. Starting in autumn, the leaves may turn yellow, develop spots, partially dry out, or gradually fall as the plant enters vegetative dormancy.

During the cold season, specimens may be delivered with reduced foliage, leaves with an aged appearance, or even no leaves, depending on the time of year and growing conditions. This is normal for the species and does not indicate a viability problem.
