Growing plants in full sun can be challenging unless you choose varieties that are tolerant of these conditions. Many full sun plants are also tolerant of drought and arid conditions, makin ghtem ideal for potted environments too. Many full sun plants will be perfectly happy with sun 14 hours a day, every day. Some plants are happy with sun 14 hours a day, unless it gets hot then they like some afternoon shade (when the sun is hottest.)
These plants prefer 4 to 6 hours of sun a day and would be happiest getting their sun mostly in the morning and/or evening with shade through the middle of the day. If a plant is called partial sun the emphasis is on making sure the plant gets at least 4 hours of sun a day. If a plant is called partial shade then greater emphasis is placed on the plant not getting more than 6 hours of direct sun.
They like less than 4 hours of direct sun a day and prefer morning and evening sun to mid-day sun. Full shade plants should also do outstanding in dappled shade conditions. An area that will be shaded by a fence or wall will need to get several hours of sun in either morning or evening for plants to do well. Full shade does not refer to dark places. All plants need at least some light.
