Plant your Agave attenuata ‘Boutin Blue’ in well-draining soil. Use a porous soil like Kellogg Palm & Cactus Mix to mix with your native soil or use straight out of the bag as a potting mix for patio containers. In coastal gardens, plant in full sun. In hotter, inland gardens, provide light shade in the hot afternoons to help prevent leaf burn.
After planting, thoroughly water to help the soil settle around the roots. Water as needed when the soil is completely dry. This agave looks better with regular to occasional irrigation. Protect plants from snails, they love the soft tissue of the Agave attenuata varieties.
This frost-tender agave will get damaged if temperatures fall below 32℉. Fatality may occur if temperatures drop below 28℉. Consider a site that is protected from frost, or move plants to a warmer area if night temperatures should drop below freezing.
The Blue Fox Tail Agave seldom produces offsets. Its root growth and pupping is not as robust as green Agave attenuata. Light intensity can affect the leaf color of the Blue Fox Tail Agave; in shadier locations, the leaf will become a deeper green.
Agaves are monocarpic plants, which means they only flower once when they reach maturity. The rosette will eventually die when the flower is done blooming. The plant can remain in flower for a long period of time. Any offsets or pups will continue to grow until they mature and flower. Agave attenuata ‘Boutin Blue’ flowers on a 5-10 ft. tall vertical flower stalk followed by seed pods. Blue Fox Tail Agave may bloom after 7-11 years depending on environmental circumstances.
'Boutin Blue’, 'Nova', 'Huntington Blue', 'Arboleda Blue', and 'Blue Boy' are all the same blue Agave attenuata. They are selections from seeds that were originally collected in 1970 by Myron Kimnach and Fred Boutin in Jalisco’s Sierra de Minantlan. The seedlings were distributed by Huntington Botanical Gardens where Fred Boutin worked as a botanist.
