Camellia leaves show genetic white or pink stripes or viral irregular white spots, mottles, and ringspots depending on cause. Viral variegation produces symptoms that vary yearly and irregularly across branches. Neither genetic nor viral forms harm plants; some growers desire them. Use virus-tested stock if unwanted. Check soil pH and provide supplemental iron if yellowing becomes problematic.
