Your choice of crops should depend not only on personal preference. It should depend on market demand, customer preference, and soil fertility. When you choose your crops or flowers, it is better to assess the cost of growing them and the profit you can earn with each harvest.  While some crops and flowers are affordable, some require extensive care, labor, and expense only to generate adequate profits.  Market gardening usually implies a small area of land. Choosing crops and flowers which don't require much growing space but still generate abundant produce is a bankable idea.
