Comments

3/22 Forsythia went from bud to brown due to temps in teens on day buds were ready to open - only a few survived to open.���
4/17/2017 I only saw 1 blossom on the Star Magnolia - it's in the pics I'm sending so others may have been on earlier, but it is definitely the last!������������

The purple coneflower is only visible as tiny green new leaves sprouting out of the ground. A large area has been dug around some of the garden.���
