Developed and introduced by University of British Columbia Botanical Gardens. This is a vast improvement on the older varieties of Spiral Rush. The plants are grown at the edge of ponds or water gardens, in boggy areas, among wet pebbles or rocks.
Leaves of Unicorn plant are round and stem-like, with a unique corkscrew spiral all the way up to the tip. The selection is tall and sturdy, with a deep green colour and evergreen habit in mild-winter regions. Flowers are brownish and insignificant. ‘Unicorn’ is a superb choice for beside a pond or stream, as a marginal water garden plant, or in any damp sunny area. Great foliage for cut flower arranging. Stems may be trimmed back hard in spring. Unicorn is a corkscrew rush cultivar that was selected by the University of British Columbia. It is a vigorous plant featuring stems which are taller (plants grow to 18” tall with a slightly wider spread), slightly more twisted, and darker green than those stems found on f. spiralis plants.
