Bean’s brief mention of Ilex hookeri (1981a) noted that it was rare in cultivation, and the situation does not seem to have changed much since that observation. The only current record of the species in TROBI is of an 8 m individual in the Ventnor Botanical Garden on the Isle of Wight, and it would seem to be distinctly tender. There is, however, a tree at Wakehurst Place, collected by Tony Schilling in mixed temperate forest on the Yallung Ridge, Nepal in 1981 (SCHL 2537). This was 2.1 m tall in 1996 (Kew database), but has since lost its main stem and is now producing shoots from its base up to 2 m tall (S. Andrews, pers. comm. 2007).
Plants previously grown by Hillier Nurseries in the United Kingdom have turned out to be I. dipyrena or I. kingiana. All three species have very spiny juvenile foliage and they are easily confused.
