Blooming Magnolia Trees
Is it unusual for magnolia trees to bloom in the fall in livingston,nj
and why? And if not why?
Usually Magnolias bloom in the spring; however, some varieties do bloom
into the fall such as the following one:
Magnolia grandiflora - Southern Magnolia var. Victoria Southern Magnolia is
large evergreen leaves, fragrant white flowers that bloom all summer into
Different species have different "phenologies" or timing/periodicity of
flowering. Sometimes related to amount of light or the temperature, and at
other times related to the availability of pollinators.

Yes, it is unusual, but this has been an unusual year, especially in the
northeastern United States.
My suspicion is that the hot weather coupled with the drought caused some
plants/trees to go dormant (some which did not did not survive). Once the
weather cooled and the rains arrived, the plants emerged from this
artificial dormancy. I have seen holly bushes around my house in flower,
and this is also an uncommon occurrence this time of year. The worry
is....if the plants think this is 'spring', will they be able to prepare
enough for when cold weather arrives? Normally the clues to the seasons are
length of day and temperature. Hopefully, as the days shorten and the
nights continue to cool, the plants will harden off the new growth which is
occurring late in the season; if this occurs, they should come through the
real winter ok.
Thanks for using NEWTON!
