Please don't forget to watch for frost now. If it's going to be around freezing, and clear and still, you may have frost. Cover your lilacs until the sun is on them!
We still have a nice assortment of deep purple lilacs available this spring.
Japanese tree lilac. Very fine upright form, more tree-like than shrubby. These line the street in town on the way to my train station, I love seeing them in spring. Late. Pokluda 1973. Syringa reticulata subsp. reticulata 'Ivory Silk'
