Syringa meyeri Palibin
So here are my 2 dwarf lilacs in their full glory. These are in bud and just waiting to flower. This is a much smaller species of lilac that what we are used to but has all the benefits of one of the best shrubs for fragrance. I love this but smaller and daintier shrub.
It can grow up to 1.5m. I comfortably keep mine at about 1m.
There a few semi dwarf lilacs. We have Syringa pubescens Miss Kim and Syringa Josee.
