-- NOTES (from wikipedia, some of this might get implemented)
-- rhizomes are edible
-- outer portion of young plants can be peeled and the heart can be eaten raw or boiled and eaten like asparagus
-- leaf bases can be eaten raw or cooked
-- sheath can be removed from the developing green flower spike, which can then be boiled and eaten like corn on the cob
-- pollen can be collected and used as a flour supplement or thickener
-- Typha stems and leaves can be used to make paper
-- The seed hairs were used by some Native American groups as tinder for starting fires

-- support for i18n
