Flower shops are a risky business proposition. Many get a big portion of their revenue on two single occasions: Mother’s Day and Valentine’s Day. The product they sell is not perceived as essential. They need to be as close as they can to their best customers and this requires paying expensive rents to be in high-end neighbourhoods. Then there’s the inventory problem: flowers start to die the moment you cut them. Within three weeks, they’re rotting in your fridge.
