Agave ovatifolia 'Frosty Blue' (Whale's Tongue Agave) - A solitary (non-offsetting) succulent that grows from 2 to 5 feet tall by 3 to 6 feet wide with a rounded rosette of short, wide gray leaves that are distinctively cupped. Leaves have small teeth along their margins and a 1 inch long dark gray terminal spine. This particularly nice form was selected by Sean Hogan of Cistus Nursery who notes that "it has an almost turquoise hue and some nice powdery overlay (oh, and a smoky after finish!). It has been noted that this species has stayed smaller in hot dry locations where water has been withheld but responds well to irrigation and grows much larger. When this plant flowers it forms a 10-14 foot tall spike with greenish-yellow flowers. Plant in full sun in a well-drained soil. A drought tolerant plant but plants grow considerably larger when given regular irrigation. Has proven hardy down to at least 4-5░ F. This Agave occurs naturally at elevations from 3,700 to 7,000 feet int the Sierra de Lampazos in northern Nuevo Leon in northeastern Mexico. It was originally collected and distributed around 1894 by Mrs Anna Nickels as Agave "Noah", but was never properly described or published under this name. ("Proposal to reject the name Agave noah (Agavaceae)" in the November 2003 issue of Taxon (52) by Greg Star, JosÚ Villarreal, Eduardo Estrada & Manuel de la Rosa). This plant was once synonymized with Agave wislizenii by Trelease in 1911 and more recently included with A. parryi. It was properly described as Agave ovatifolia by Greg Starr and Jose Angel Villareal (STARR G, VILLARREAL JAQ. 2002. "Agave ovatifolia (Agavaceae) Una Nueva Especie De Maguey Del Noreste De Mexico" Sida 20 (2): 495-499). The specific epithet, from the Latin words 'ovatus' for "egg" and 'folius' for "leaves" is in reference to the broad ovate leaves and the common name, whale's tongue agave, also describes the leaf shape. There is speculation that this plant was distributed in California unnamed but there is no documentation on this or information how this plant performs in cultivation in California. As it is similar and related to Agave parryi the presumption is that it will grow as well as Agave parryi does in cultivation - so far this has proven true. Our original stock plants of the species plants were purchased from Starr Nursery in 2004 and micropropagated tissue culture plants of this selection first came to us in 2009 from Shady Oaks Nursery in Minnesota. The specific epithet, from the Latin words 'ovatus' for "egg" and 'folius' for "leaves" is in reference to the broad ovate leaves and the common name, whale's tongue agave, also describes the leaf shape.

We will also incorporate comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes cultural information that would aid others in growing  Agave ovatifolia 'Frosty Blue'.
