I think I've been in florists to send condolence flowers more often than for any other reason which is not a pleasant association. I've never done that in Columbia as far as I can remember though, and so was never in Kirby Croft According to the archived version of the their website, the company started in 1947. That's a 63 year run, which is something the family can be proud of.
The sign on the front door leaves some hope for the future, but apparently not in this location as the building is up for sale. It's a very ineresting building too, with the bay window and the house-like main section. It's almost exactly across the street from former KFC and not too far from the old Varsity, Kershaw Tires and the old Eckerd's. I'm afraid this section of Main has seen better times.
