Christchurch Botanical Gardens Palm Update

Post by Rod »

Hi there,
Just went down to the Botanical gardens to see how the palms are going before winter starts.
I have not included all the Trachycarpus fortunei and the Canary Island Date palms in this post, as these are grown all over Christchurch, but have only posted the ones i am keeping an eye on and the more rarer ones.


Rhopalostylis sapida - In a very sheltered spot.

Parajubaea coccoides - I'm surprised it got through the last two cold winters?
The Botanical gardens weather station recorded temps down to -5°c ( 23°f ) last year.
This palm had only two spears on it a year ago, and its a fairly new planting

Parajubaea t.v.t - pic 1
This is the much bigger one.
Parajubaea torallyi var. torallyi grows relatively fast in our climate. Much faster than a Canary Island Date palm, and second only to Washingtonia robusta.

Brahea armata ( This is a fairly new planting - i think 2-years now )

Image

Chamaerops humilis var. cerifera - nice and compact
This palm is now correctly called; Chamaerops humilis var. argentea

Image

Washingtonia robusta - planted about 2-years ago

Image

Jubaea chilensis - planted about 2-years ago

Hi Troy - Thanks for the comments.
I'm gonna get me a Chamaerops humilis 'cerifera' now correctly called 'argentea' ( why do they keep changing the names ) I want one potted on the deck.
Parajubaea tvt is also one of my favorites. Cant wait till mine gets that big also.
Yours will look fantastic - given your mild climate and the huge variety of palms you can grow there.
I think i counted around 40-species from your last video posted on GOTE

Image #2 is not a Parajubaea t.v.t
I found out it is a Parajubaea coccoides ( By the person who planted it ).
The Botanical gardens weather station recorded temps as low as -5°c ( 23°f ) last winter.
This palm tolerates frost better than a Nikau does here in Christchurch.

All looking very good Rod, does your garden see the same temps as the botanical garden ? The brahea and jubaea are my favourites.

Hi JBALLY
My garden is slightly milder than the botanical gardens ( 0.5-1.0°c )

I had a small Parajubaea coccoides a few years back, grew ok then suddenly died during the middle of summer! Have heard they are sometimes a fussy palm which can croak for no apparent reason, which is a shame as they look more attractive than Parajubaea T.V.T imo...

Hi Nathan
They grow fine in New Zealand right up to between 15-20yrs old, then go into decline ( Always after flowering for the first time )
No one has figured out what the issue is yet?
So far no issues have been found with Parajubaea t.v.t ( Yet )

Hi Kris
No Parajubaea sunkha planted here at the Botanical gardens ( And probably none in Christchurch )
But there are some planted in gardens in the north island.

Any Ceroxylon, Rod? Or does it get too hot in summer for them?

I'd guess a fungal disease that infects through the flowers. Similar case in Britain with Blue Douglas-fir Pseudotsuga menziesii subsp. glauca, it grows very well when young, but the disease Rhabdocline pseudotsugae infects the first cone crop, and then spreads into the foliage from the cones, and the tree slowly declines and eventually dies.

Hi Greville
No Ceroxylon that i know of. Might be a bit too cold in winter. ( Summer heat should be alright, as temps drop significantly during the night )
