How long does it take for a lilac to start blooming?
"It normally takes up to 5 full yrs before they bloom at all"... Is this TRUE?!? I've never heard that before, & it seems a bit hard to believe... Especially considering the newer cultivars that are receiving rave reviews (like 'Bloomerang'); they wouldn't be so popular if they took so long to bloom--right? So, is there any truth to this claim at all?? Are there SOME lilacs that take that long? How long does a TYPICAL lilac take to bloom??
Old-fashioned lilacs (Syring vulgaris) may indeed take up to 5 years to bloom. However, the smaller types, such as Bloomerang or Meyer lilac usually will bloom within a couple of years. Of course, it also depends on how mature the plant is that you start with. A liner or whip (unbranched twig) will take an extra year or two to reach blooming size versus a well-branched container-grown shrub.
