Rooftop farms are most common in cities with high land and real estate costs, like Washington, DC and New York City. Some rooftop farmers build growing containers from scratch, but this may be limited to the edges of roofs where the existing architecture is strongest. Other rooftop farmers retrofit existing green roofs to produce crops for sale. Common crops are strawberries (Figure 7), vegetables (Figure 8), and cut flowers (Figure 9).
