What is the plant

A fun and whimsical evergreen plant with endless decorative purposes. Low maintenance and sturdy, a perfect fit for those who seek aesthetics without rigid care techniques.

From North America, Unicorn Reed Grass, also known as Corkscrew rush, can be identified by a tall and sturdy array of round and twisted evergreen stems that present a corkscrew effect. Its foliage is a rich deep-green color that makes it perfect for flower arrangements and other decorative purposes.
Despite its looks, the stems are soft to the touch and bear clusters of insignificant flowers in shades of pale brown. This is an easy-to-care, low-maintenance plant that is virtually disease free.

How to Care for the Plant

Water
Unicorn Reed Grass enjoys damp substrates, so try to keep the soil consistently moist. Watering should be done regularly, although this plant can tolerate less and more water. It performs well near lakes, ponds, and other bodies of water and can even be in standing water up to 4 inches (10 cm) deep.
Pruning
Its usual growth is between 8-40 inches (20-100 cm), so personal preference can have a say in pruning habits, but stems should always be trimmed back in spring.
Fertilizer
This plant doesn't need fertilizing.
