From late spring to early summer, 'Moonbeam' dazzles with a profusion of delicate, tubular flowers. These blooms are a stunning combination of yellow with a dab of red at the throat, creating a striking contrast against the green foliage. The flowers are not only visually appealing but also attract pollinators such as bees and butterflies to the garden.

The plant features attractive, lance-shaped, deep green leaves that provide a lush backdrop to its vibrant flowers. The foliage remains neat and tidy throughout the growing season, adding to the plant's appeal.

A tough and undemanding subject for the rock garden, and tidy enough for a crevice garden as well.
