'President Lincoln' has upright panicles of violet buds that open to Wedgewood blue, fragrant flowers. Use as a hedge or screen, or in a shrub or foundation border.
Grow in well drained soil in full sun. Tolerates a range of soil types, but best growth occurs in sandy-loam or clay-loam soils. Lilacs sometimes don't bloom, and it is usually because it was pruned too early or too late in the season, or it's getting too much nitrogen fertilizer. Lilacs bloom on old wood, so prune immediately after bloom, as buds for the following year begin to set practically as the flowers fade. For tips on pruning, see Guides.
