French and Spanish lavenders, however, are more tolerant of our summer climate. You can grow French and Spanish lavender in your garden, then pot up the French lavender to move indoors during winter. Spanish lavender is more cold-tolerant and can usually pull through winter here, but you could also pot it up in late fall. Now that they have grown taller, they are no longer yellow but green. I have them on the shady side of the house.
Sunlight affects variegated foliage.
Generally, variegated leaves need light to hold their variegation, but the amount varies. Yellow variegated leaves generally color best in sun, but if the foliage is thin, it will scorch. White variegated leaves generally hold their color best with some shade, especially if the soil is on the dry side. Variegated plants may originate as random seedlings or as mutants on an all-green plant. In plants with red or purple variegations, the chlorophyll is masked by other pigments.
