What is the bloom time for cattail?

May to July is the bloom time for cattails [Typhaspp]. This wetland native reaches a mature height of 3 - 9 feet [0.9144 - 2.7432 meters]. Tiny yellow flowers cluster above the plant's hallmark, sausage-shaped cluster of brown flowers. The yellow flowers wither at the end of bloom time and leave behind a bare stalk. The flowers are considered a delicious boiled treat in traditional Native American cooking.
