Directly opposite the passage leading to the Rose Garden or the Podzámecký Pond you will come across the hyacinth lilac (Syringa hyacinthiflora), which was planted here in 1910 by the founder of the park, Count Arnošt Emanuel Silva-Tarouca. It stands out above all for its dense fringe of fragrant pinkish-purple flowers, which will stand out against the background of light green heart-shaped leaves in May and June. It is a cross between the broad-leaved lilac and the common lilac (Syringa oblata × Syringa vulgaris). Did you know that botanically, lilacs belong to the Oleaceae family?
