Agave ovatifolia G.D.Starr & Villarreal
Whale's Tongue Agave
Agave ovatifolia is a succulent plant that forms a solitary rosette of broad powdery bluish-gray distinctively cupped leaves with small teeth along margins and a dark gray, up to 1 inch (2.5 cm) long terminal spine. The rosette grows up to 5 feet (1.5 m) tall and 6.6 feet (2 m) in diameter. A mature rosette forms an up to 16.4 foot (5 m) tall spike with several side branches, each with dense clusters of greenish-yellow flowers.
USDA hardiness zones 7b to 11b: from 5 °F (−15 °C) to 50 °F (+10 °C).
How to Grow and Care
Agaves are not difficult plants to grow. They are slow-growing and dramatic and will even thrive on a bit of neglect. If you are the type of person who likes to fuss with houseplants and water a lot, Agave is probably not the plant for you. On the other hand, if you are 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 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 species commonly found in cultivation grow very slowly and will take a long time to outgrow their pot. It is also best to handle your plant as little as possible since they do not like to be disturbed. When you repot, refresh the spent soil with a new potting mix and ensure 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.
