Plant your Agave desmettiana 'Variegata' 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. The leaf color and variegation of Agave desmettiana 'Variegata' may change depending on the light intensity. The yellow variegation may be less pronounced in shadier locations.
Thoroughly water after planting to help the soil settle around the roots. Water as needed when the soil is completely dry. This agave is drought tolerant but will also handle regular irrigation with no adverse impact. Protect plants from snails.
Cold sensitive, the use of frost-cloth may help protect your agave from frost damage if temperatures fall below 32°F. Cold hardy to 25℉.
The Variegated Dwarf Smooth Agave will produce numerous pups or suckers that will eventually form a cluster. For a tidy appearance or to maintain size, remove the offsets with pruners to divide and/or dispose of pups. They are easiest to remove when they are young and small.
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. The remaining offsets or pups will continue to grow until they mature and flower. Agave desmettiana 'Variegata' typically matures and blooms after 10 years on a 8-10 ft. tall stalk followed by bulbils (baby plants) along the flower stalk.
Years of spelling the specific epithet (A. desmettiana) with two Ts exist on the web and in books. The proper spelling of the specific epithet is likely Agave desmetiana 'Variegata' (one T), which honors the Belgian horticulturist Louis De Smet (1810-1887).
