Attalea dubia

My A. dubia is still chugging along. Probably still worth a try in 9a which is better than any other Attalea I know of!

can winstand heat waves in full sun??? this climate area gets neat 44 degrees of drought heat for near a couple of weeks every summer... lower temp -1 -2 for around a couple of hours 5 to 6 nights per winter... i get no frost damage on phoenix roebellini, bismarckia , some spots some years in syagrus coronata... can also grow coccothrinax crinita

This guy is a turd. It went into the winter with pinnate fronds. I protected it with blankets and radiant heat. I forgot one night and the fronds were smoked. Spear pull soon after. Death confirmed yesterday.

But I did discover something interesting I didn't know. Attalea dubia has an underground heel. I wonder how many other palms have heels that simply stay underground.

Is one of the reasons it croaked not i was protected with blankets and radiant heat and suddenly left unprotected ? How cold it was that night Buffy?

Very promising....what was your lowest temps since you planted?

[Kailua_Krish]

Hmm, probably around 20-22. Im not sure if it experienced that low as the planting location is good and protected (under an oak and near the house surrounded by concrete). I threw a pillow case over it but Im not sure if that actually did anything. No damage from my recollection.

Its just started to go pinnate so you can see how slow it grows in this climate

Just wanted to provide an update. Ultimately, this palm, at least the seeds sold to me as Attalea dubia, are not very cold hardy. Freeze damage begins at around 28F. By the time you get to the lower 20s, it's just smoked. It's not a promising choice except in 9B and up. I've tried several Attalea, and they all seem to act about the same. It was a good long trial, but I'm willing to walk away from it.

Sorry to hear that. It grows well in our short thermometer climate for those with patience.  Prefers to emerge from some shade.
