Umbrella plant is a close cousin of the papyrus plant of ancient Egypt. All the leaves are arranged a top triangular stems they are narrow and flattened and only 6 to 10 inches long (15-25 cm). They are symmetrically arranged around the stem in a disk, resembling the petals on a daisy. Small greenish flowers grow at the center of the disk. As the small fruits form they change to golden and then dark brown.


The plant will be smaller and less invasive when grown in drier or less fertile soils.


It can be easily grown in good garden soil.


The light could be sun or shade. In bright sun, clumps will be compact and the stems closely packed. Under shady conditions clumps will grow higher and be composed of fewer stems giving a more graceful aspect.
