Archontophoenix cunninghamiana

Recommended Posts

Rafael

This one faced three back to back nights with -1,8ºC, -2,6ºC and -3,8ºC, this one with not light frost. This in December.

These recent days, one isolated and frosty night at -3,6ºC.

In the middle one night at -0,5ºC.

Then, some strong frost in two nights.

Light frost in another two nights.

However, this palm is located in the south side of the yard, in a place almost non atacked by frost.

And is a big sized palm.

As you see, not yet totaly burned.

I am expecting the recovering, after February :drool:

I would not trim the old leaves for a few weeks yet as they act as insulation. But, based on the size, I would think it will recover if the spear is still green.

Mine suffered no damage from a night down to -2 at 10:30 pm, then freezing until a spell of -1 at dawn. This was part of a prolonged cold spell with successive nights at or just below freezing. No frost.

If yours is less than totally burned, I suspect it will recover quickly. Coconuts with similar damage come back well.

This palm cant really be a cunninghamiana, besides what the colour of flowers and seeds tell us...

Maybe an hybrid.

rafael: Nope. No way, IMO, it's a cunninghamiana, not with that tight crownshaft. Looks like a typical A. alexandrae to me, based on how my own alexandrae palms look.

Walt, i dont know if it helps if you check photos and words of this topic: http://www.palmtalk.org/forum/index.php?showtopic=21044&st=0&p=351481&hl=cunninghamiana&fromsearch=1&#entry351481

But, anyway, by its behaviour facing frost, i bet its an alexandrae too!

Raffael what happened to your cunninghaniana? What do you think the limit was, was the frost dry or wet?

Interesting! Your latitude is similar to mine I'm about 41deg south, what are you growing and is there a link to your weather records in Portugal

I am actually growing several species in two quite different places, despite being close to each other. These are my zone pushing species: bismarckia, syagrus coronata, copernicia alba, euterpe edulis, kentiopsis oliviformis, hediscepe, prichardia hillebrandii, dypsis decaryi, ravenea rivularis, syagrus sancona and scizophylla. I am growing too archontophoenix illawara, cunninghamiana, alexandrae, myolensis, tuckery, maxima and purpurae.

Dont know about weather record links here. In a normal winter we have -1 C as minimum and 16C as maximum. 35C/14C in normal summer. High rainfall levels and lots of fog (ceroxylon, orianopsis, Rhopalostylis, dypsis decipiens and howeas love it). Things dont grow fast here, unless they are truly fast species ^_^

Interesting, I have just started a new garden in Tasmania, my temperatures are probably 3 degrees less than yours all year round, the most tender species I've planted so far is r.sapida and s.romanzoffiana.  I think these are right on my limit and may need occasional protection from extreme cold. No chance of Bangalow plans unless under heavy canopy and even if they did make it they would look tatty and brown.

Note that most of the tender palms i have mentioned are growing in a quite sheltered spot. In most of the unsheltered spots nearby almost all would die in the next winter. I found the perfect spot ^_^
