Agave valenciana was described in 2006 by Miguel J. Cházaro-Basáñez, José A. Vázquez-García and Yalma L. Vargas R. from the state of Jalisco, Mexico. This gigantic plant can grow to 5-7 feet tall and 10-12 feet across. Dark green leaves are quite large, reaching 5-7 feet long by 1-2 feet wide. The 20-25 foot tall flower stalk has 2-3 inch long, bright yellow flowers in the late spring. I have not tested this for winter hardiness yet, but suspect that they will need some protection when winter lows dip below 30 degrees F. Plants have a moderately slow growth rate in the desert and could be grown in a large, decorative container for a number of years as long as it is grown in some shade and gets covered in the winter.
