Hypheane coriacea cold hardiness

[Marius]

Hi Everyone 

I need cold hardiness information for Hypheane coriacea please. I bought a nice sized one on the KZN South Coast yesterday from an indigenous nursery. I want to plant it in full sun, but that will mean no overhead canopy for frost protection. 
 

My garden gets -1 or -2 deg Celsius for a day or two during a bad winter. Mostly between 0 - 2 degrees for most winters. Day temps between 12 and 16 degrees.

Former IPS president Dr. U.A. Young, had several huge specimens in Tampa, Florida USA that survived snow, 19 and 21F in the late 1970s and 1980s.  Of course they were badly damaged, one trunk even losing a small portion of its pseudo bark.  Years later, the palms were no worse for wear.   Unfortunately, the palms could not survive the bulldozer.

are you going to plant the Alluaudia with it? 😜

I actually had a strap-leaf seedling survive 9°F (-13°C) in San Antonio with just being covered with mulch.  I planted another seedling here and it was unfazed with 27°F (-3°C).

@Rod had his more sensitive Hyphaenes all survive 22F in 2007 or 2011, whichever bad freeze Arizona had.  I don't think they looked good after the freeze, but they're all back in business now.

No. I’ll put that elsewhere

Really I just want to know why you don't have all the Hyphaene considering most are native to somewhere either a.) in your neck of the woods or b.) closer to your neck of the woods than any other PTer lol

Hypheane palms are only grown by specialists here and are rarely available for sale. In SA the only one of our indigenous palms that is widely available is Phoenix reclinata. 
I only found out that I can probably grow Hypheane successfully here on palm talk.

Nice palm 👍

Hey Marius, hoe gaan dit met u? I can see our climates are very similar so I'm curious to see what else you grow. Following!

Hi @Than  Dit gaan goed. Dankie. 
I have just over 85 palm species in the ground in my garden. I grow a lot of South African native plants. I grow aquatic plants and am now starting to add bromeliads to my garden.

I've looked into it and there is a massive difference in our climate. You get rains in the summer, we get them in the winter. You are lucky to have dry cold and I bet you can grow many more stuff than I do, despite the same temperatures!
