The graceful, arching leaves form loose mounds that slowly spread by rhizomes. The foliage of 'All Gold' is entirely golden yellow, especially if grown in full sun. Slightly faster growing, more upright and larger than H. m. 'Aureola'. Provide shade and sufficient moisture in warm, dry climates. Full sun acceptable only in cooler, moist climates. Use singularly or in mass in woodland gardens, shade gardens, borders, or containers.
