Lilac
Lilac is native to the Balkan Peninsula, and actually belongs to the olive family, Oleaceae. It naturally grows on rocky hills as shrubs or small trees, but it’s now commonly grown in home gardens. They’re often used as border plants and can even be mixed into loose hedges, but some varieties are small enough to use for foundational planting. Their bark is grey and their stems are smooth.
The lilac’s leaves are light green and oval, while their flowers are tubular and usually come in colors of lilac, blue, and sometimes white. They are quite prone to mildew disease so they must have really good circulation and regular pruning.
