The UW Botanic Gardens Elizabeth C. Miller Library Website has a list of Garden Tours and Plant Sales

After some web searching here is a list I have come up with. Thought I would share in case anyone else is interested. Feel free to add other sales I may have missed!

The one already linked to is the one I always use.

While we're talking sales, has anyone heard any mention of the plant sale and garden open usually held at Bloedel Reserve early Spring? It seems like I've been there first or second weekend in April in previous Springs but I'm not finding any notice this year...

I see nothing about it on the Bloedel web site, which has information about other April events on more than one page.

I wonder if the Heronswood plant sales have replaced the Bloedel ones. ...
the first one this year at Heronswood is May 17, 2014
