We sometimes get up to12 hours of sun in full-on summer, depending on what part of the property the plant is in. There are some plants that can tolerate that...bless their hearts! Most plants cannot. Summer days like today that are fairly cloudy are well appreciated and quite rare. Now if we could just get some RAIN! I guess we're probably not in any optimal zone here...too many plants have committed hari kari here in the past.
