Small pinnate specimen (1gal size), planted mid-2009, exposed position. Looked fine through a few light/moderate frosts & freezes as low as 28.6F. Began to show moderate-to-major foliar damage with two back-to-back freezes to 25.9F. The big freeze of 2010 (64 hours continuously below freezing, lows of 23, 18.4, 19.7, 19.8) has completely toasted exposed foliage. I have it mulched to the spear and expect it to recover from below this point. This one is not as leaf-hardy as I had hoped, it seems no hardier from that perspective than A. arenaria.

3 gallon plant planted in heavy soil (clay/topsoil mix) in March 2010. Lows around 21 have oldest fronds slightly damaged and newer fronds are spotted but still look fine, especially from a distance. No overhead protection and we had extremely heavy frost. This plant has been much hardier than queen palms (defoliated) and is continuing to grow throughout the winter, a new leaf has recently opened.

Krishna,
How is it doing now?
Darkman in Pensacola - Looking for cold hardy palms and plants that make Pensacola look tropical
Life - Some assembly required, Side effects frequently experienced, Mileage may vary, As is no warranty, Batteries not included, Instructions shipped separately and are frequently wrong!
Kentucky Bourbon - It may not solve the problem but it helps to make it tolerable!
Statistics - Opinions that analyst twist to support the insanity of those that pay them.

Krishna,
How is it doing now?
That was the update from last weekend when I went home
As you know it has been a couple of weeks since Florida has had any really cold air come over and it has warmed up nicely which is why I think its still growing.-Krishna
