Hey Bepah, I saw your question about lutescens and cold tolerance. I am in an area where the average lows are close to the same. I have seen these palms take the upper twenties briefly (1night) and survive okay. The most exposed leaflets get fried but the plant lives and recovers its nice looks quickly (in plant time).
Do you see many of these growing in yards where you are? I am guessing you're in California. I've often wondered if they are popular outdoors out that way.
