MEDITERRANEAN SURVIVABILTY INDEX ZONE 4B: The Manila Zone
I would divide this zone into two zones: very marginal palms (30-32F), and super marginal palms (32F and above). This latter zone, at least in my experience, is the highest zone in the Mediterranean climate range. Any palms less hardy than these cannot survive any known Mediterranean climates, and you will have to look under the tropical climates to find them.
Very marginal Palms (30-32F minimums):
Acanthophoenix rubra, Aiphanes aculeata, Aiphanes lindeniana, Areca triandra, Arenga australasica, Astrocaryum mexicanum, Basselinia pancheri, Burretiokentia koghiensis, Burretiokentia viellardia, Calyptronoma (Calyptrogyne) occidentalis, Calyptronoma rivalis, Carpentaria acuminata, Caryota cummingii, Caryota no, Caryota rumphiana, Chamaedorea allenii, Chamaedorea amabilis, Chamaedorea correae, Chamaedorea dammeriana, Chamaedorea deckeriana, Chamaedorea fragrans, Chamaedorea minima, Chamaedorea nubium, Chamaedorea palmeriana, Chamaedorea rhizomatosa, Chamaedorea robertii, Chamaedorea rossteniorum, Chamaedore schiedeana, Chamaedorea sullivanorum, Chamaedorea whitelockiana, Chelyocarpus chuco, Clinostigma savoryanum, Coccothrinax spissa, Daemonorops sp., Desmoncus sp., Dypsis sp. Bejofa, Dypsis sp. Cerecea, Dypsis lanceolata, Dypsis lastelliana, Dypsis manajarensis, Dypsis pembana, Dypsis pilulifera, Dypsis pinnatifrons, Dypsis pusilla, Dypsis sahanofensis, Dypsis sanctamariae, Gaussia attenuata, Gaussia princeps, Geonoma weberbaueri, Hyophorbe lagenicaulis, Hyophorbe verschaffeltii, Johanesteijsmannia magnifica, Kentiopsis magnifica, Latania sp. (all), Licuala radula, Licuala sarawakensis, Linospadix palmeriana, Livistona humilis, Livistona jenkinsiana, Pinanga philippinensis (elmeri), Polyandrococus caudescens, Pseudophoneix lindeniana, Pseudophoenix vinifera, Ptychococos lepidota, Ptychosperma macarthuri, Ptychosperma salomonense, Raphia australis, Ravenea sambiranensis, Reinhardtia gracilis, Roystonea altissima, Roystonea violacea, Schippia concolor, Syagrus pseudococos, Syagrus vagans, Synecanthus warscewiczianus, Thrinax excelsa, Zombia antillarum.
Super marginal palms (32F+ minimum)- only a few talented growers living in the perfect climates can grow these palms, though many of these have not grown to maturity, and some doubtfully ever will in a true Mediterranean climate:
Arena undulatifolia, Caryota zebrina, Chambeyronia lepidota, Clinostigma harlandii, Cocos nucifera, Copernicia macroglossa, Copernicia rigida, Cyphosperma balansae, Dypsis nodifera, Dypsis rivularis, Geonoma congesta, Geonoma interrupta, Iguanura wallichiana, Kentiopsis piersoniorum, Kerriodoxa elegans, Marojejya darianii, Marojejya insignis, Pritchardia pacifica, Ptychosperma burretianum, Reinhardtia simplex, Roystonea oleracea, Satakentia liukiuensis, Veitchia joannis, Veitchia winin
Special Case palms: These are super difficult palms, that some manage to grow in a Mediterranean climate, but do not necessarily have a cold hardiness issue, but rather a picky climate issue- either need it to be not hot, not cold, or not rainy
Ceroxylon parvifrons and vogelianum- these palms are not super cold sensitive, but they sure are heat sensitive. Some can grow them, but most find they up and die suddenly, expect for those living in a coastally cool climate like that found in San Francisco.
Juania austalis: not a super cold sensitive palm but very limited climate tolerance. Grows well in San Francisco, but that is about the only climate in the US where success has been found.
Lepidorrhachis moorena: similar situation to the above palms, but not quite as finicky, as several southern Californians have grown this palm well... all along the coast where it doesn't get too hot.
Livistona inermis: this palm NEEDS heat... only survives in the desert communities in a Mediterranean climate... a lot easier to grow in warm, humid climates, though.
As far as I know, no one has successfully grown Adonidia for more than a few years in a true Mediterranean climate... but almost. I would probably rate that palm as the most hardy of the palms that can ALMOST grow here.Palmbob 23:03, 21 July 2007 (PDT)
