Container gardening isn’t right for every plant; some cannot take being “pot bound” and not being allowed their roots to expand. Having container plants allows for garden portability--a freedom to move them around and have different looks depending on the atmosphere you’d like to create. They are used for patios and decks with great results. Plants that live year round in pots without much water, drought-tolerant container plants, can be good for beginning container gardeners who may forget to water on occasion.
