Most of the events, for families, schools and tourists alike, will last through the weekend (hint: A visit would make a great last-minute Mother's Day treat).
National Public Gardens Day always takes place on the Friday before Mother's Day, and is meant to commemorate the start of spring.
Get outside in your hometown or travel to a nearby public garden to celebrate spring – not to mention good ol' mom.
All the gardens mentioned below are free to enter. Check the National Public Gardens Day website to get coupons to gardens that charge admission on Friday.
