Sparganium erectum
branched burr reed
A vigorous rush-like plant with branched spikes of greenish- brown flowers in late-summer followed by prickly, teasel-like brown fruit. Branched burr read is best planted in the shallow margins of a wildlife pond. Avoid using with flexible pond liners since they're at risk of damage from the plant's sharply pointed rhizomes.
