About Celtica gigantea (Link) F.M.Vázquez & Barkworth
Celtica gigantea is a bunchgrass species with narrow, gray-green leaf blades that form a foliage clump 2 to 3 feet (0.61–0.91 m) across. Its foliage stays green year-round to semi-evergreen, depending on the local climate. In late spring, the plant produces prominent flower spikes that first emerge with a silver-lavender color. Over the summer, the spikes mature to a bright golden hue, and they remain on the plant as a tan color through winter. These flower spikes typically reach 8 feet (2.4 m) in total height, growing well above the plant's lower foliage. This grass is cultivated as an ornamental plant, grown as single individual plants or in large grouped drifts for parks, public landscapes, and home gardens. It is commonly included in plant palettes for drought-tolerant gardens and Mediterranean climate gardens. The tall golden flower spikes are considered attractive when growing on the plant, and they appear particularly glowing when backlit by sunlight. These spikes can also be harvested and used as dried flowers. Under its older scientific synonym Stipa gigantea, this species and its cultivar 'Gold Fontaene' have been awarded the Royal Horticultural Society's Award of Garden Merit.
