It’s easy to get excited about the first tulip or even the first dandelion in the yard (OK—that might be a stretch). But what about those plants that don’t get all the love and attention, yet still brighten up those first few months of the gardening season? Today we’re honoring those unsung heroes of the spring garden—plants that need a better PR agent because they’re marvelous, but not very well-known. We’ve got a few native dark horses and even a shrub that Steve thought he’d never like. To get you really laughing we revisit some childhood memories of using spring plants in mischievous ways. Finally, we debut a new segment where we give a brief look into what’s going on (good, bad, and ugly) in our gardens right now.   Expert testimony: Bill Cullina is the executive director of the University of Pennsylvania’s Morris Arboretum.
