Blooming Times Delayed by Cool Weather


Blooming times in the Longenecker Horticultural Gardens and native plant restorations are later than average, in fact, nearly the latest ever for some things.
Lilacs will be at their peak bloom around the week of May 20. Crabapples should peak around May 15. Magnolias, Serviceberries and the cherries are at peak bloom the week of May 6. High winds or heavy rain would bring down Serviceberry and cherry blossoms. Unseasonably high temperatures would accelerate blooming and unseasonably cool temperatures will slow it down.
Woodland wildflowers are still blooming in Gallistel, Wingra and Noe Woods.

This 1,260-acre arboretum also houses flowering trees, shrubs and a world-famous lilac collection. Educational tours for groups and the general public, science and nature-based classes for all ages and abilities, and a wide variety of volunteer opportunities for groups, families and individuals are available.
