Cortaderia selloana, commonly known as pampas grass, is a flowering plant native to southern South America, including the pampas region after which it is named. There are around 25 species in the genus Cortaderia.
This highly ornamental grass grows giant pink-colored feathery plumes that reach heights to 13 ft tall. The plumes are collected and saved for use in dry flower arrangements or standalone vases.
It is a tall grass, growing in dense tussocks that can reach a height of 3 m (10 ft). The leaves are long and slender, 1–2 m (3 ft 3 in–6 ft 7 in) long, and 1 cm (3⁄8 in) broad, with very sharp edges. The leaves are usually bluish-green but can be silvery grey. The flowers are produced in a dense white panicle 20–40 cm (8–16 in) long on a 2–3 m (6 ft 7 in–9 ft 10 in) tall stem.
When deciding where to plant your pink pampas grass, choose a space that receives at least 6 hours of sunlight per day. If grown in rows, space plants 4-6 inches apart. Choose a well-draining, fertile soil. Sand, loam, peat, and clay soil types show the best results. No fertilizer is required for this fast-growing grass. Prune in late winter for new spring growth.
The surface sows the seeds as sunlight is required. Germinate in warm temperatures or start indoors. Keep seeds and soil moist throughout the germination phase (3-4 weeks). Tip: Keep soil moist by using a mister versus a heavy pouring water vessel so the seeds stay at the top of the soil.
