Again, same zone but very different climates.

I love seeing those coconut palm in south Florida, makes the area very tropical looking,
but I noticed coconut palms in Hawaii seem to be quite a bit taller on average,
not sure if that's to do with climate difference (ie. cold snaps).
Yeah, you're right, it's not entirely true. Coconuts grow in Deep Sourth Texas and some parts of Central FL.

Florida's coconuts are mostly a different species that are naturally shorter, but the taller ones they have don't grow as well as HI because of cold snaps and Lethal Yellowing.

Actually, the talls are more vigorous and cold hardy. Sadly, they were almost completely wiped out by lethal yellowing decades ago.

Only a few survive, these are in West Palm Beach

Florida is a large area... and there are many parts I’ve never been, but from my travels around there seems to be many taller (bigger than 60 feet) coconut palms in the older areas. From what I can tell (and this is just a guess on my part), cities and towns that are the oldest seem to have the most extensive gardens and the oldest specimens. Although coconuts are very sensitive to cold temps I’m sure, I’ve seen 100 foot coconut palms as far north as Melbourne, FL (about 250 miles north of Miami) – but Melbourne was a big resort in the 1940’s, so they have lot of older specimens.

One spot that I’m actually familiar with is the 1000 – 1200 block of Ocean Drive in Miami, they have many 60 to 100 foot coconut palms there it seems:

The Washingtoinia’s I’ve seen in drier climates are taller than the ones I’ve seen in wet climates – but I have seen them even in Miami. In north Florida, Washingtonoia’s are everywhere in Ormond, Daytona Beach, St. Augustine…etc. So they must be able to handle the rainfall/humidity of subtropical climates:

This is south of Jacksonville:





I’m no expert, but from just guessing, these types of palms are the most common in some areas of the southern half of Florida. I think there called Cuban Royal Palms/Florida Royal Palms?

Those are Washingtonia robusta though, which do grow well in humid climates, I was referring to Washingtonia filifera, which don't like wet/humid climates. Many people mistake Washingtonia's with slightly fatter trunks as W. filifera, when infact they are more than likely the hybrid W. 'filibusta', which can also handle wet/humid climates & have fatter trunks than regular W. robusta...

Wavehunter, those last ones are indeed the Cuban Royal Palms. For them, it's the opposite of the desert palms: they'll do fine in dry places like San Diego or Phoenix, but much better in humid climes that are warmer in winter.

A lot of the very tall and old coconuts are actually found in colder areas relative to Miami Beach(Southwest Florida, Treasure Coast, a few barrier islands in Central Florida) where lethal yellowing didn't spread due to chance or cold (insect that spreads the disease can't tolerate cold). Some places such as West Palm Beach inject their palms with antibiotic solutions to prevent them from dying of lethal yellowing.

Coconuts are a lot hardier to cold than people give them credit for. An hour or two at 32F is not going to hurt a "tall" type coconut that much. They will defoliate at 28F, but often survive if the next winter is mild. The Malayan "dwarf" types found throughout S. Florida are a lot weaker and less hardy to cold; but they are resistant to lethal yellowing.

Seems to me that it would be in their best interest to either bring in a different variety of coconut tree, or hybridize the two to produce a tall & relatively cold hardy coconut palm that is immune to LY.

Most of the coconuts in S. Florida are Malayan Dwarf or Maypan (half dwarf/half tall) coconuts which are resistant to lethal yellowing. They aren't as beautiful and robust as the old talls though

You know your palms very well. I never heard of all these hybrids, but then again no one around where I live grows palm trees.

Are these hybrid Mexican Fan Palms as well? They look different to me yet again. The trunk looks different, but the leaves look similar. I think in the background are a couple of Queen Palms. These are in a suburb of Savannah.

I'm a bit of a geek when it comes to palms I have been a member of the European Palm Society since 1993 & the International Palm Society almost as long...

Yes those look be either robustas or more than likely filibustas, the one in the middle of the top photo looks like a Sabal though, difficult to tell for sure as they have been heavily pruned. The palms in the background are indeed Queens (Syagrus romanzoffiana) & the blue leaved palms in the second photo are Butia capitata, again hardy in milder parts of the UK...

Another way to tell robustas & filiferas apart, when small, is that filiferas have a totally green petiole down to the trunk/stem & robustas is coloured maroon close to the stem/trunk. Hybrids are variable & can have a lot of maroon colouring or none at all, but usually they have at least some, which makes it difficult to distinguish them from pure robustas...

There is no way you could mistake a pure Washingtonia filifera when mature though, their trunks are FAAATT!!
