"The Buttered Popcorn', Ranunculus repens, is a great ground cover that vigorously spreads to 4'. Its broad finley cut leaves are silvery-green with a variegated chartreuse edge. It has delicate yellow flowers in late spring but is mostly grown for its striking foliage color. 'Buttered Popcorn' needs to be planted in a full sun location with well-drained soil."
