Some people see flowers only as beautiful plants that may smell nice. But flowers can increase the health of your garden, and help you grow more food.
Different flowers attract different types of pollinators such as bees and butterflies, which help food crops to grow.
Some plants, like eggplants, tomatoes, and all fruiting trees and bushes, need or will greatly benefit from pollinators or else they will produce very few or no fruits or vegetables. Tomatoes can self pollinate by pollen being blown from one flower to another, but it produces a low yield or harvest.
So please, when you plan your fruit and vegetable garden, consider planting some flowers, too. The happier your pollinators are, the happier your plants and soil will be.
