which had become extinct on the Canary Islands, explaining why some of these species are rare and considered endangered (Vogel 1954; Vogel et al. 1984; Olesen 1985; Valido et al. 2004). However more recent work has shown that these plants are adequately pollinated by non-specialist flower visiting birds, particularly the Canary Islands chiffchaff (''Phylloscopus canariensis'') and the Canary Island spectacled warbler (''Sylvia conspicillata orbitalis'') (Olesen 1985; Ollerton et al. 2008), and in fact show some specific adaptations to infrequent pollination by these birds, such as extended flower lifespans (Ollerton et al. 2008), and a hexose-dominated sugar ratio of the nectar (Dupont et al. 2004). In frost-prone areas, ''Canarina canariensis'' is best grown under glass in the winter. It has gained the
