Design IdeasUse this plant to lend an exotic, tropical character to plantings both in and out of the water. Umbrella Grass is ideal for planting in Asian ceramic containers and is a good alternative to more invasive Bamboo. Plant on the margins of water gardens in conjunction with landscape boulders or where drainage is too poor to support other plants.
Companion PlantsThis water-garden plant from the sedge family combines well with aquatics like Horsetail Reed Grass (Equisetum hyemale) and Variegated Japanese Water Iris (Iris ensata 'Variegata'), with its purple butterfly-like flowers. More terrestrial combinations may include the white-flowering African Iris (Moraea iridioides) and Tomlinson Natal Plum (Carissa macrocarpa 'Tomlinson'). In milder climates combine Umbrella Grass with the exotic Kaffir Lily (Clivia miniata 'French Hybrid') and Everblooming Gardenia (Gardenia jasminoides 'Veitchii').

History:
This is not a grass but a sedge counted in the Cyperaceae. It's native to South Africa and classified by Heinrich Schrader, a German botanist of the early 18th century.
Lore:
Because there are number of Cyperus species such as nut sedge that have become pernicious, invasive weeds, these eager plants are often maligned with their badly behaved relatives.
