Syringa pubescens aka Lilac

Syringa pubescens is a shrub known as hairy lilac. It belongs to the olive family, Oleaceae. Its native range runs from China to Korea. Kew places it in the temperate climate zone. The Chicago Botanic Garden describes its origin as northeastern Asia. The RHS confirms that it is not native to Britain or Ireland. These records describe the species, rather than one named garden form. Its rounded shape and scented flowers are its main garden features.

The flowers are lavender and grow in large clusters. Their scent adds interest while the shrub is in bloom. Chicago lists the flowering season as May through June. Its account places the main display in early June. This gives a useful guide to bloom time in Chicago. The record does not give dates for other growing regions. It also lists butterflies among the wildlife the shrub attracts. That supports butterfly interest, but does not identify its main pollinator.

Choose a site in full sun for this lilac. The Chicago account calls for rich soil that drains well. It also stresses the need for air to move around it. Good air movement helps prevent disease on the leaves. Avoid a cramped position that blocks air around the plant. Chicago gives a USDA hardiness range of zones 4–8. Its supplied care data lists a moderate water need. The species record does not give a soil pH range. It does not name a specific pest or leaf disease.

The rounded shrub can serve as a hedge or screen. Chicago also lists it for use as a specimen plant. In that role, its form and flowers provide the main interest. A sunny site should also allow air around the shrub. The evidence does not give a species-level height or spread. Sizes listed for separate subspecies do not establish this species' garden range. The same limit applies to their leaf and fruit details. The supplied species records do not describe bark or stems.

The evidence does not establish edible parts for this species. It also gives no species-level finding on toxicity. Its use in gardens does not prove that eating it is safe. No medicinal use or conservation status appears in the supplied species records.
