Hakonechloa macra 'Aureola' is primarily valued for which characteristic?

Hakonechloa macra 'Aureola' is primarily valued for its vibrant yellow foliage, which provides an eye-catching contrast in gardens and landscape designs. This ornamental grass is known for its striking variegated leaves that take on bright golden tones, particularly in the spring and summer, adding a lively touch to shaded and partially shaded areas. The ability to light up dark corners of the garden with its colorful foliage is one of its main aesthetic appeals, making it a popular choice among gardeners and landscapers.

While other qualities may hold merit, such as potential resistance to drought or a vigorous root system, they do not overshadow the primary reason why this cultivar is cultivated. The insect repellent properties mentioned could be associated with many plants; however, they are not a characteristic feature of 'Aureola.' This grass is primarily appreciated for its stunning appearance rather than functional advantages.
