For five days in the middle of February, when the last thing on your mind is spring gardening, this show comes to town. But don't worry, you won't be cold because this show takes place inside the Washington State Convention & Trade Center. Information booths and plants from landscapers, nurseries and noncommercial gardeners fill more than five acres of display space. Whether you have a green thumb or want a green thumb, this is the ultimate event. See their website for further information.
