Flowering plants are generally divided into two categories: annuals and perennials. Though they can be used interchangeably, each has its own pluses and minuses.

Whether you choose annuals, perennials, or a mix of the two, be aware of each plant's cultural requirements: in plain terms, the amount of sun and water they need to thrive. Sun-loving plants will struggle in shade; likewise, shade-loving plants will never be happy in full sun.

Watering needs also vary. Some plants need plenty of water, while those that are more drought-tolerant can be harmed by being watered too much. Make it easy on yourself; choose plants that match the conditions in your garden, and put plants with similar sun and water requirements together.
