Agave americana Century plant
This enormous plant flowers from May to August and after flowering the mother plant dies. Underneath this plant and around it will be many small suckers which will grow. It lives for approximately 10-30 years, not a century as it's name suggests. The leaves can grow to 2metres, and the yellow flowers can grow as much as 8 metres. The leaves are so strong and are very dangerous as they can even pierce bone. The plant originated in Mexico but is now naturalised in Spain and other countries.
