Lanonia magalonii

I purchased this palm as a 2 leaf seedling from Floribunda on March 26th, 2018.  I have grown it inside my greenhouse with temperature range from 50-85 F.  It grows new fronds readily, but they don't seem to remain green for very long.  The trunk diameter is now about 1.5 inches.

  This palm is supposedly more tolerant of cool temperatures, but what temperatures really ?  Howeas grow 4-5 fronds per year in San Diego, but I get 2 fronds per year.

What are your comments about trying this outdoors in San Francisco with average daytime temps of 55-65 F?   Thanks !

Hi Darold. 
 

This is mine, also grown from a 2 leaf seedling around the same time. However, it has been left outside year round here in Melbourne. We’re at a similar latitude to San Francisco but get slightly warmer in summer and colder in winter from my understanding. Based on the local official weather station, this one has seen temperatures from 0.0C (32F) to 43.5C (110F) in the last year. 
 

In a protected position I’d expect it will survive for you, but expect growth rate to be very slow. At least it is a nice looking palm even at seedling size.

Lan magalonii is abundant in Bach Ma National Park near Hue.

My observation is that it grows on slopes/cliffs beside the watercourse. My thoughts are that they would like good drainage but also moisture.

Great Lanonia in Brisbane if kept moist in our dry winters. Lots of leaf forms also. I've seen it entire to 7 segments.

Should be there now. Sigh....

Also Lanonia calciphila should be more cold tolerant from its range further north in Ninh Binh near where dasyantha is found in Vietnam

That’s a beauty Darold. Well grown. I’m trying dasyantha with mixed results and I believe it is hardier than magalonii. Steve beat me too it about these in habitat. I saw tonnes of them in Bach Ma N.P.  Bach Ma is at altitude and you can definitely feel the temperature difference compared to the lowlands but it’s not high enough to be cool to cold at all. It’s probably like comparing Brisbane to Cairns. I’m not surprised they do well in Brisbane. They’d feel at home I reckon. It’s great to see one doing well in Melbourne. There’s some better growers than me here.

If it was me Darold I would keep it in a pot as a specimen but let it enjoy the warmer part of the year outside and in the coldest part of the year protect it somehow.
