Agave salmiana var. ferox 'Variegata'
Agave salmiana 'Butterfinger'
Agave salmiana var. ferox 'Variegata' is an attractive succulent that forms rosettes of wide, dark green leaves with strong yellow bands along the margins. The rosettes can grow up to 6 feet (1.8 m) tall and up to 6 feet (1.8 m) in diameter, producing offsets around the base. The leaves are armed with brown to grayish-brown marginal spines and a long terminal spine.
The mature rosette sends up a stout, candelabra-like inflorescence bearing clusters of yellow flowers. The plant is monocarpic, which means the rosette dies after flowers.
Agave salmiana var. ferox 'Variegata' is a variegated cultivar of Agave salmiana var. ferox. The origin is unknown.
USDA hardiness zone 8b to 11b: from 15 °F (−9.4 °C) to 50 °F (+10 °C).
How to Grow and Care
Agave is not a difficult plant to grow. They're slow-growing and dramatic and will even thrive on a bit of neglect. If you're the type of person who likes to fuss with houseplants and water a lot, Agave is probably not the plant for you. If, however, you're the type of person who likes to set it and forget it, and you have a sunny window, Agave might be the way to go. Be aware that some of the large varieties will eventually outgrow your room (unless you have a large greenhouse), and Agave can be aggressive. They have irritating sap and sometimes very sharp thorns that can cause injuries to small children and even pets.
In general, Agaves do not need to be repotted every year. Most of the species commonly found in cultivation grow very slowly and take a long time to outgrow their pot. It's also best to handle your Agave as little as possible since they do not like to be disturbed. When repot, refresh the spent soil with a new potting mix and make sure the plant is firmly anchored in its pot. However, be careful not to pot the Agave too deep as that will encourage stem rot during the growing season.
