This description is for Syringa pubescens subsp. Microphylla: A native of Western China, Syringa pubescens subsp. Microphylla is a deciduous shrubby lilac. It has attractive clusters of fragrant pale purple or pink flowers and will grow to around six foot high. It tends to grow wider than it does high, having a spread of up to twelve feet. Butterflies love this lilac so you should find they visit your garden more regularly if you plant this. As it grow wide, it can be used to create an interesting and attractive hedge. Youll get the best floral display if you plant it in full sun, but it will also grow in light shade. Removing the dead flower heads will give you extra blooms the next year.
