According to the new USDA Plant Hardiness Zone Map, I am now in zone 6a instead of 5b, but just barely. I'm not surprised, based on my experience the past few years with frost dates in both spring and fall. So I am going to be bolder about gardening earlier this year. In fact, I can hardly wait.
Yesterday I noticed daffodils poking through the ground on the south side of the West Wing. Crazy!
