Kogane Mushi Japanese Boehmeria (Gold Bug). This perennial is a new 15-24" tall, variegated woodland perennial from Japan. The foliage emerges bright gold in the spring and we have usually grown it in a shaded environment. But upon visiting Moore Farms Botanical Gardens in Lake City, SC, they were growing it in practically full sun and it was overwhelming. Here it was doing unbelievably well. This is definitely a foliage plant as the flowers are mostly inconspicuous. Interestingly, the Japanese cultivar name means "gold bug."
