Description
editCeltica gigantea is a bunchgrass with leaf blades that are narrow and gray-green, creating a bunchgrass foliage mass 2–3 feet (0.61–0.91 m) in diameter. It is evergreen to semi-evergreen, depending on the climate.[4]
The plant has prominent flower spikes emerging silver-lavender in the late spring, aging to a radiant golden over the summer, and persisting in tan into winter. The spikes typically grow to 8 feet (2.4 m) tall, rising high above the foliage.[5][4]
Cultivation
editCeltica gigantea is grown as an ornamental grass for planting as single specimens and massed drifts in parks, public landscapes, and gardens.[5] It is used in drought tolerant and Mediterranean climate—plant palette gardens.[4]
The tall golden flower spikes are attractive on the plant, especially radiant when backlit by the sun.[6] They may also be used for dried flowers.
Under the synonym Stipa gigantea this plant[3][7] and the cultivar 'Gold Fontaene'[8] have won the Royal Horticultural Society's Award of Garden Merit.
