The upper and lower sides of the leaf are shaped differently. The fibrous, horny leaf margins are serrated flexibly. The strong brown to gray terminal spine is 2.5 to 7 cm long.
The paniculate, racemose inflorescence is up to 2.30 m high. The yellow flowers appear singly or in clusters and are 48 to 55 mm long. The wide flower tube is up to 4 mm long. The elongated three-chamber capsule fruits are 25 to 30 mm long and 12 to 14 mm wide.
The flowering period extends from April to May.
Systematics and distribution
Agave × peacockii grows in Mexico in Hidalgo , Puebla and Oaxaca on dry limestone slopes , in woodlands from 1000 to 1800 m altitude. It is associated with succulents and cactus species.
The first description by George Croucher was published in 1873. Synonyms are Agave ghiesbreghtii var. Peacockii Terracciano , Agave roezliana var. Peacockii Trel.
Agave × peacockii is a member of the Marginatae group . The species is suggested to be a natural hybrid between the sympatric Agave marmorata and Agave kerchovei . The intermediate inflorescences, which show features of both the subgenus Littaea and the subgenus Agave , are characteristic. The species is cultivated in the Huntington Botanical Garden in San Marino, California.
