Comments

  Full bloom on the Gold Tide forsythia was a little difficult to determine. We had several heavy freeze/frost in the area. Many of the buds were frozen 
Missed first bloom on 'Charles Joly lilac' was believed to be dead. Had only one complete flower. 
Leopardbane could not be located Spring 2009.
