Surprisingly cold hardy, Agave ovatifolia 'Frosty Blue' (Whale's Tongue Agave) is an evergreen, perennial succulent forming a solitary rounded rosette of thick, broad, distinctively cupped, gray to powdery-blue leaves. Adding interesting texture and interest year-round, the leaves are lined with small teeth along their margins and tipped with a dark gray terminal spine. Mature plants (over 10 years) flower only once. They are topped with a magnificent flowering spike that can reach 14 ft. (4m), and bears dense clusters of yellow-green flowers. 

• Grows up to 3-4 ft. tall and wide (90-120 cm). May reach 14 ft. (4 m) with flower stalk.

• Great for coastal gardens, city gardens, rock gardens, succulent gardens or Mediterranean gardens. Ideal as an accent plant in sunny borders or in decorative containers.
