How far south do citrus trees grow and fruit in NZ?

All of those palms? Really? Even Juania australis?? This is an incredibly rare palm... Do you have any pics?

The palms are the usual suspects, but the L chinensis and P torallyii, are the first ones I've heard of surviving any length of time in the UK. Do you need to protect them?. I can't get J australis to grow here, as the dry conditions in summer seem to dry them out, and I tend to let palms fend for them selves.
Yep most of the palms I grow can't be grown in many parts of the UK. Phoenix canariensis & Washingtonia robusta for example only survive in the very mildest parts. I don't protect any of them, the only ones I used to protect were the more tender ones which are now dead... My Juania was planted about 8 years ago as a 2ft tall plant & it's now getting on for 9ft tall. It is planted in a south east facing corner, so it only gets sun in the morning as they are reputed not to like high temperatures, so I thought a spot out of the afternoon sun would do it better, as we can get hot & sunny weather in the summer, if not as often as I'd like! I do have to water it like mad during the summer though

I can't recall them south of Timaru (about 2 hr south of Christchurch)at 44.30 S, although they probably grow in sheltered pockets. On the West Coast, I have seen them at at Jackson Bay (44 S), which is about as far south as the road goes on that side

Whats the snow data for Scilly also it record low is -11 celsius. Im sure we could support other palms.
Do you mean the palm in the attached picture infront of the City Hall in Victoria? That is a Trachycarpus fortunei, not a Washingtonia...

And Washingtonia do grow in Scilly, also attached is a photo of a 50ft Washingtonia robusta on Tresco, photographed this year... Tresco also has many mature Phoenix canariensis over 100 years old, they also had mature & fruiting Rhopalostylis sapida & Archontophoenix cunninghamiana, but these were killed during the freak winter of 1987 when it dropped to -7C there. Some of the Rhopalostylis self sown seedlings did survive however & are now starting to trunk again...

There are quite a few Washingtonia robusta growing in milder parts of the UK, some around 20ft or so tall, so they don't need summer heat to grow well...

Whenever I see a pic of tender vegetation sitting hard right up against a building like that (first pic) I suspect heat from that building, urban heat island if you will, has a lot to do with the survival. I have a weather sensor in my back patio in a very dense rowhouse urban neighborhood, and for three years now have never seen the temp go below 17f. That is a quite a diff from the National Weather Service Airport lowest temp in those last three years which was 8f in January 2011 (one of the coldest winters on the east coast in years).

Imo that really doesn't represent the true vegetation potential of an area when it is situated that close to a building like that.

Yes buildings can provide extra heat for more tender plants to be able to survive, but saying the palm in that photo, Trachycarpus fortunei, is very hardy & grows even in Scotland.

Airports are notorious frosts traps, the large open areas of flat ground cause much lower temperatures than surrounding areas, it's the same in the UK where many Met Office weather stations are located at airports, the temperatures in nearby towns are much warmer, so airports don't really give a true representation of an areas temperatures...

But your post said originally it was infront of City Hall & was 30ft tall??

Do you have any photos of this Washingtonia then? Or of any that are planted elsewhere?

Many airports are also located in frost hollows too (i.e Exeter, Bournemouth, Southampton, and to a lesser extent, Manchester).

He/she doesn't have any photos because there are no mature washingtonias in Victoria...

I have been to the city hall there and there are just trachycarpus as you said. Do a google search for palm trees in Victoria/Oak Bay and virtually all of them will be trachycarpus you will see.
