Christchurch Botanic Gardens Autumn 2019

Recommended Posts

sipalms

Took a look around the Christchurch Botanic Gardens' every increasing collection this morning, a beautiful early autumn morning around 57 (15C) degrees before a sunny 86 (30C) day..

Probably more suited to the Cold Hardy forum... but includes a number of 9b palms. Pretty good for 43 degrees south (similar to southern Ontario Canada).

Having trouble resizing pics but will start with a few. and add more as we go.

Nice stand of Nikau (both mainland and chatham island)

Dypsis decipiens? Looks like it's had a few transplant issues but is putting out nice big spear/s.187409402_PTTemplate(13).jpg.12d3a0121598edab2b0674653495a460.jpg

This parajubaea is huge and very fast growing.

That is probably my dream Climate. Not tropical but mild enough to grow such a nice variety of palms.

Very cool. I had a good look around those gardens in November 2015 and thought that Nikau stand must have gone in since, otherwise how did I not see it. 

Found this article.

So they have got through a least two full winters already, their prospects look good then.

There are at least 5 or 6 palms that will grow anywhere in the country except the high mountain areas.

Yeah I would say the nikaus have been in the ground for more like 4-5 years. 

The most obvious absence is a queen palm. Definitely would be a success there and a nice addition. Even an Alexandrae may even be a possibility with a bit of TLC.

I think maybe Arenga micrantha.  Are there any Hedyscepes down there?  Nice pics, thanks. cheers Richard

The main target Mosque overlooks these gardens. Unbelievable that such a thing could happen here.

Beautiful pictures!! That has to be one of the healthiest Parajubaea species I've ever seen photographed. :D

Thanks so much for this posting, its been almost twenty years since we have been there.  Check out the Botanical Garden in Dunedin.  Also, make a side trip just to see Akaroa across the bay from Christchurch.  It is a beautiful place, and, I think it is about 70 K away by car.  Cecile

Yes, Queens are slightly more hardy than most Nikau so would surely go ok. Up here they have a sprinker system at the main gardens to protect the topical garden which has many Alexandrae amongst more tender stuff,   but would hardly have used it the last three winters.   Still in shock about what happened so close to there last week, don't know what to add that has not been said already. Has been an all consuming event in a country with a population only a little greater than one large US city  metro area.

That is the best looking parajubaea I've ever seen.

If those Nikau do well then definitely A cunninghamania and Queens would do well too.

Curious to know why you think that? I haven't seen many parajubeas at all so don't really know what constitutes a good looker!

When this one was first planted I thought it would make an ideal palm for my home garden. Little did I know just how massive these things get very fast....

It amazes me how they can grow Parajubaea and all those other exotics in Christchurch, given their average low temperature in July is 0.5C (33F) with 80-90 days of ground frost per year. My average low temperature in January (mid-winter) is actually warmer at 2.5C (37F) and I only have 50 days of ground frost, yet I can't grow Parajubaea here, or half of the stuff they do. 

In fact their average lows are colder than me across every one of the 12 months. Heck they even average a low of 53F (11.5C) in their warmest month, which is January. Which makes it all the more surprising that they can grow all that stuff. Like fair play to them and I envy their climate, to a degree. I'm just slightly puzzled at how Parajubaea can grow there, whereas it will die after two winters in my climate. I'm marginally drier than Christchurch as well.

Christchurch has a very very unique climate due to geographical position. Because there is no continental landmass to the east, south and North, and Australia a few 1000kms to the west, we are exposed to all various weather, all the time. We have the Southern Alps starting 100km west which provide shelter from the predominant westerly flow, and creates a fohn effect making hot extremes of weather much more common than other locations around NZ.

It's not at all unusual to have a 19-23C maximum from time to time in mid winter Winter, even though the average max is 12, and it's not unusual to have a 13 degree high in mid summer after a powerful cold southerly weather system, when the average max is 23-24.

Same with lows - over the next couple of days here, it's not expected to get below 20 degrees at night. Yet the average low for March is around 10 degrees. In mid December, we could have a low of just 3 or 4 degrees after a southerly system. This makes our averages seem a poor. One time I removed all 'outliers' out of several years of daily max / mins as a bit of an experiment - just removed the one or two or three really cold summer days, and the average was drastically different, marked increase in average min/max temps. I know this is completely unscientific but it proves a point that a few unseasonable days and drastically skew what a climate seems like on paper.

In a Christchurch vs UK climate comparison the other factors to consider include solar heating, we're around 8 degrees closer to the equator than England's south coast (more like Bilbao in Spain) - Palms probably photosynthesize better regardless of external temp? Another one is daytime heating hours. There's a lot to consider....

The 10 day forecast - is showing average max 22 degrees and average min 12.4 - these are averages for mid summer and we are now in late March....

I visited a few years ago.  The Sabal palmetto was unhappy--probably never warm enough.  The garden had problems with soil liquefaction in the earthquakes, which damaged tree roots.  I heard about Christchurch's problems with heat and dry weather.  The planting program seemed ambitious.  But things are obviously coming along nicely.  

The city in general and the Garden in particular does put on an impressive alt/England display.  

The Christchurch climate is definitely not like the coastal Cornwall climate, which I got a peek at two years ago. 

BTW, I think I recall the Christchurch garden gift shop was selling lovely made-in-USA garden flamingos, which I looked for after coming home and never found.

Somewhat off-topic,  Portland, Oregon occasionally had summer winds from inland, which coming down from the Cascades, created a fohn/Santa Ana effect, so there'd be one or two 98-99 (36-37) degree days most summers.

Yeah, solar heating definitely plays a part due to Christchurch being at 43S. So the sunlight intensity will be much stronger than say at 51N in my location. This is especially apparent in winter as your daytime highs are a few degrees higher in winter.

The other big factor is that I am not on the coast, and actually 30 miles inland. So while my average temps are warmer across the board than Christchurch, except for daytime highs in winter (due to solar heating), I am however more susceptible to extreme winter lows, due to being away from the coast. My record low stands at -13C, compared to Christchurch's -7C. So that is a massive difference and the biggest factor when it comes to what you can grow, in my opinion. Although this winter just gone, my lowest was only -5C. No damage at all on the Phoenix and Washingtonia. But next winter I could easily see -10C if a polar vortex reaches us from the nearby European mainland. Whereas NZ doesn't have a large continental landmass nearby. 

30 miles south of me, on the West Sussex coast, their all-time record low is only around -8C with average winter lows generally around 5C. There are Parajubaea present on the south coast and in central London, just not inland outside of London or the south coast. Although the south coast doesn't get anywhere near as hot as me during the summer months. 

I had an average high temperature of 27C in June 2018, and 29C in July 2018, with 4 consecutive days that reached 36-37C and we also experienced a period of 10 weeks, from mid May - early August, where we did not get a single drop of rain. Combined with the mild winter we just had, I have no doubt in my mind that I could have had a Parajubaea thriving here, but it's really not worth the risk, or the investment, because when that one cold winter does hit, with lows down to -10C, they will be toast.

That's the problem with my climate. You'll get the exotics through back to back mild winters and have them thriving after the hot, sunny summers... but you'll be lured into a false sense of security, only to get caught out by a polar vortex that we get once every 3-4 years. Again, Christchurch doesn't really have that problem. Even if your average lows are generally lower than mine here. You still aren't looking at a one off -10C once every 3-4 years...
