Sending flowers in time for Valentine's Day may be a little harder this year. The building housing the nation's largest flower shipping business burst into flames in southern Florida -- a week before Valentine's Day.

The owner of Armellini Industries in Palm City said that 53 trucks transporting Valentine's Day flowers already were on the road when the building caught fire. The owner says the fire could not have come at a worse time.

Officials believe a roofer making repairs from hurricanes Frances and Jeanne started the fire when he replaced something with a torch. The fire marshal is still investigating the fire. The damage was estimated at $1 million.
