The Josee lilac (Syringa vulgaris 'Josee') is a three-way cross between S. meyeri, S. patula and S. microphylla. This dwarf lilac is advertised as a reblooming variety. However, it is more inclined to rebloom in cooler climates such as Canada or the Pacific Northwest.
The Josee lilac can be planted in zones 2 through 9 in full sun to partial shade. It produces panicles of lavender-pink trumpet-shaped florets that attract butterflies and hummingbirds. As a dwarf lilac, the Josee only reaches a height of 4 to 6 feet and a spread of 4 to 6 feet. To encourage reblooming, deadhead the spent blooms.
