Petasites japonicus 'Variegatus' (Butterbur)
Bold and awesome groundcover perennial for the lightly shaded garden. Big, rounded leaves grow on plants to about 4' tall and will spread quite a bit if given a wet spot. But in moderate moisture conditions it will not spread too aggressively. Yellow blooms are produced in May and June but honestly, nobody cares because the variegated foliage is so awesome!
