Syringa josikaea capsule, splitting in two to release the two winged seeds. Growing conditions allow for cool to temperate climate and are fully frost hardy. The plant also grows in full sun to semi shade. Despite its continental European origin, it has proved to be surprisingly successful when cultivated in the oceanic extremes of northwestern Europe on the Faroe Islands and in arctic northern Norway north to Kirkenes. It has hybridised in cultivation with the closely related "Syringa komarowii" from China; the hybrid is named "Syringa × josiflexa". Syringa josikaea Syringa josikaea, the Hungarian lilac, is a species of lilac, native to
Gracillaria arsenievi Gracillaria arsenievi Gracillaria arsenievi is a moth of the family Gracillariidae. It is known from the island of Hokkaidō in Japan and the Russian Far East. The wingspan is 10-13.2 mm. The larvae feed on "Fraxinus americana", "Fraxinus chinensis", "Fraxinus mandshurica", "Fraxinus pennsylvanica", "Syringa amurensis", "Syringa reticulata" and "Syringa vulgaris". They mine the leaves of their host plant. The mine starts as upper epidermal and tortuous-linear, and later becomes a blister-like blotch. The leaf roll made by the larva of the late instars is conical or trigonal, always rolled up from the tip of the leaf or leaflet on the
