Century Plant

Description:

From Wikipedia: The misnamed century plant typically lives only 10 to 30 years. It has a spreading rosette (about 4 m/13 ft wide) of gray-green leaves up to 2 m (6.6 ft) long, each with a spiny margin and a heavy spike at the tip that can pierce to the bone. When it flowers, the spike with a cyme of big yellow flowers may reach up to 8 m (26 ft) in height. Its common name likely derives from its semelparous nature of flowering only once at the end of its long life. The plant dies after flowering, but produces suckers or adventitious shoots from the base, which continue its growth.
