Cyperus alternifolius ‘Zumula’ – Pet-Safe Cat Grass Cultivar of Umbrella Papyrus
 
Cyperus alternifolius ‘Zumula’ is a compact cultivar of umbrella papyrus (Cyperus alternifolius L., published in Mant. Pl. 1: 28, 1767). Unlike the tall pond plant known as umbrella sedge, this form was bred for indoor use: softer, shorter, and perfectly safe for pets. Often marketed as “cat grass,” ‘Zumula’ produces fresh green shoots that cats and dogs can nibble without risk. With its upright, umbrella-shaped tufts, it’s also an attractive houseplant that doubles as a pet-friendly accent.
 
 
Distinct features of Cyperus alternifolius ‘Zumula’
 
This cultivar forms dense clumps of bright green, reed-like stems topped by narrow leaf-like bracts, giving the plant its umbrella shape. Indoors it usually grows 30–60 cm tall, much shorter than the wild type, and is commonly sold in 12 cm nursery pots. Its compact size and soft foliage make it ideal for windowsills, balconies, or as a decorative companion plant in mixed displays.
 
 
Origin and cultivar background
 
Cyperus alternifolius L. is native to Madagascar, thriving in wetlands and riverbanks. ‘Zumula’ was selected as a softer, compact cultivar suitable for pot culture and specifically marketed as safe cat grass. While the wild species often exceeds one meter in height, this cultivar stays manageable, growing back readily even after regular grazing or trimming.
