I am and they are hard to keep alive when young. They are a 10a palm and they cant take full sun until they get a trunk. They are kind of slow as well.

they are 10a on east coast... not doable even in 10b on west coast, so might not do well in your Mediterranean climate (needs TONS of water, too). But I really dont know your climate well. Other than warmth, water, and more water, they are fairly typical palms as far as needs to. In Hawaii, these are not that slow, but not that many palms are slow there.

In Madeira temps in winter never drop below 16 C and rest of year 20c upto 30 C. So never cold. Plenty rain in winter months. Described as Sub Tropical. You can wear T-Shirt and Shorts all year round. It's above Canary Islands off the west coast of Africa. So I hope this is enough to make Carpoxylon happy? Agree it's not Aruba weather , but should be fine to grow many palms . Carpoxylon had a lovely trunk but slow growth may mean better for me to buy a larger plant to start with.
