I was there with the Hobby Greenhouse Group years ago. Has gardens all over the place plus you can tour the house, too. Much more plants *& gardens and not as HUGE to tour as Winterthur.
Spring Garden Weekend: Longwood, Winterthur, Mt. Cuba
Winterthur is huge, for sure!
Right now, we're focused on the Philly show next week, since Jim's parents will be coming up to join us for that. Aloha!
