Tropical Plants Follow Shifting Climate North

As gardeners start tilling, climate change has given them a host of new plants to plant. As the climate has warmed, the landscape has - literally - changed. Plants that only 15 or 20 years ago would not survive a Northeast winter, can now thrive. Spring thaws are coming earlier, and fall freezes are coming later, giving plants a significantly longer growing season.
