and southwest Turkey, but has not been adequately tested for hardiness. Date Palm (Phoenix dactylifera) – This relative of the Canary Island date palm, and producer of the edible date, is also hardy to about , but does not tolerate very wet areas. This palm is one of the staple plants of the Middle East for its versatility and edible fruit. Mule Palm (× Butiagrus nabonnandii) – Hardy to about . Manmade hybrid between the Butia palm and Queen palm. One of the hardiest feather palms. It combines the hardiness of the Butia palm with the fast-growing, tropical fronds of the Queen palm. Mature specimens are quite rare due to the difficulty in producing this palm and the characteristics and cold tolerance of the palm is variable with each specimen. Many of them resemble coconut palms. Ceroxylon quindiuense – It is native to the Colombian Andes where it is found at above sea level. At this altitude it tolerates occasional frosts for short periods of time. Ceroxylon alpinum – It is native to the Andes. Archontophoenix cunninghamiana – native to Australia, and Beccariophoenix alfredii High plateau coconut palm are slightly frost Hardy Coconut palm lookalikes. Howea forsteriana – It is native to Lord Howe Island in Australia. Rhopalostylis sapida – It is native to New Zealand. It is southernmost palm in the world found as far south as 44°S. Caryota species – They are generally considered tolerant to occasional frosts. Dypsis decipiens – It is native to Madagascar. Queen palm - Adult specimens can even survive up to -6 °c. Plants referred to as palms Some plants used in subtropical landscaping in temperate climates like much of Europe, northern China/Japan, Korea, the northern USA, New Zealand, etc. that are commonly referred to as "palms", but are not palms, i.e. not members of the Arecaceae family, include: Aloidendron barberae, Beaucarnea recurvata, Cordyline australis, Cordyline indivisa, Cycas revoluta, Dasylirion, Cyathea australis, Cyathea capensis, Cyathea cooperi, Cyathea dealbata, Cyathea medullaris, Dicksonia antarctica, Dicksonia squarrosa, Dioon angustifolium, Dioon edule, Encephalartos, Macrozamia communis, Macrozamia johnsonii, Macrozamia riedlei, Mahonia eurybracteata, Mahonia oiwakensis, Musa basjoo, Musa sikkimensis, Pseudopanax ferox, Rhus typhina, Xanthorrhoea, Yucca aloifolia, Yucca gigantea, Yucca rostrata and Zamia integrifolia. Hardiness In general, hardy palms can only tolerate brief periods with temperatures in the range . As such, this generally limits hardy palm cultivation and long term specimens to zone 7a or higher.
