Euphorbia Tasmanian Tiger'By Janet Loughrey
Some of the most fascinating foliage is variegated, meaning it has two or more colors. Leaves can be splashed, splattered, veined, streaked, marbled, striped or mottled. Euphorbia characias 'Tasmanian Tiger' has thin, creamy margins; Agave 'Spot' has irregular splotches. Those with consistent patterning in each leaf are generally more highly prized, but some such as Houttuynia cordata 'Chamaeleon' display an uneven mix of colors.
