Botanical Name

Plant Common Name

General Description

The robust and delightfully feminine French lilac ‘Big Blue’ is a scented jewel for the spring garden. This over-sized beauty was developed by Monrovia Nursery for its extra big panicles of lilac blooms.

When not in bloom the large, rounded, deciduous shrub offers little interest, but it is exceptionally beautiful when its flower panicles appear in late spring to early summer. ‘Big Blue’ offers big panicles of large lilac blue flowers that are highly fragrant and ideal for cutting. The blooms are held at tips of the branches and attract loads of bees, butterflies and many other insect pollinators.

Lilacs develop their best habit and flowers when grown in full sun. They prefer average to fertile soil with good drainage. Though moderately drought tolerant, these lilacs grow best is given supplemental water during very dry spells. Next year's flower buds are set shortly after blooming, so lilacs must be pruned directly after their yearly display. There are several serious pests and diseases that plague them. Lilac borers can be a fatal, so keep an eye out for their telltale half-moon shaped holes along the trunks. Powdery mildew is also a yearly problem. Extreme drought stress can invite both.

French lilacs make fine feature plants. Cut their fresh blossoms for fragrant, long-lasting flower arrangements.
