(Portland, OR)  --  Portland's Bloom tour starts on Friday.  It's part walking tour and part floral show.  Local florists have teamed up with nearly 30 businesses downtown, in Old Town and the Central Eastside to create spectacular, large, one-of-a-kind floral arrangements.  The floral displays will remain in place through June 11th.  You'll find a list of the locations on the Visit Downtown Instagram and Facebook sites.
