Cyperus vaginatus (Flatsedge) - A medium-sized Cyperus relative that grows to 4 to 5 feet tall with stout, flat, dark green bracts topping the rigid stems. This evergreen aquatic forms greenish flowers in the summer.

Grow in water or in moist soil in sun or part shade. It is hardy to about 20-25 degrees F. This plant with its strong bold lines are attractive contrasted against lighter colors.

We received this plant from the amazing plantsman Gary Hammer and grew it from 1991 until 2008 using the name he called it, Cyperus textilis. This name however is considered to be a synonym of Cyperus vaginatus, a plant that grows throughout Australia. The name for the genus comes from the historical Greek name for Sweet Galingale, Cyperus longus and the specific epithet is from the Latin word 'vagina', meaning a "sheath". 

The information displayed on this page about Cyperus vaginatus is based on our research conducted about this plant from books in our nursery library as well as from information that is provided by reliable online resources. We also have included our own observations made about it as it grew in the nursery gardens and other gardens visited, as well how the crops of this plant performed in the containers when we had them in our nursery field. We also include comments received from others and welcome hearing from anyone who has information about this plant, particularly if it includes cultural information aiding others to better grow it.

 
We closed for regular business at the end of 2025 in order for the property to be developed for affordable housing.
Our gates remain closed but we will open them by appointment to interested parties through August 21st to liquidate remaining plants, supplies and equipment.
The plants remaining in the field are listed on our
Live Inventory Page.
