Pritchardia lowreyana

Recommended Posts

Phoenikakias

Anyone growing this Pritchardia sp for some confirmation? I grow one (at least bought as such), now lumped with P macrocarpa, and for second time I observe that it is hardier to frost than both Pritchardia hillebrandii and affinis. But it is considerably slower in growth and prone to potassium deficiency. So I need another grower beyond tropics, who could confirm above observation. I had a very light freezing in the past days and I today I have observed first damage signs on my Pritchardia spss but the lowreyana.

Most sensitive is the affinis:

Second comes the hillebrandii both ny small and the big one showed identical cold tolerance/sensitivity:

And now the lowreyana. All yellow/spotty/orange can be seen on crown is just potassium deficiency on older leaves. After the heavy treatment last summer with potassium, new leaves are bright green. It is quite remarkable that an old greek encyclopedia from the 50's (yes then we had more knowledgable botanists than nowadays!) mentions under the genus Pritchardia the macrocarpa as the one that can be grown in the most southern parts of the country. Of course there is always the possibility that it is another sp, this is why I need some confirmation from other growers...Photo0559.thumb.jpg.412720301da38c3a6340Photo0562.thumb.jpg.bd6a4507cdeb9b8502f1Photo0560.thumb.jpg.a3b5f46e040897f055eePhoto0561.thumb.jpg.1b2c3c761caec5969243

Cant help you with the lowreyana, which i am not growing.

in my garden i have the hillebrandii and the minor. The second one is facing its first winter. The first one has shown freeze damage  on the last winter. BUT has recovered perfectly.

My observations indicate such a small amount of difference in cold tolerance between the Hawaiian Pritchardias, that I'm more likely to consider the micro zone of each palm, more so than the species when I'm comparing any cold damage. They all seem to suffer damage at about the same temps, it's just that some of mine are more protected than others. I do however notice differences in tolerance of sun exposure & water needs, for what it's worth.

lowreyana is tougher than hillebrandii and affinis here. affinis hates the wet and dies without much of a fight. Your ID seems OK at this stage (similar to plants with that name here at least) but you need flowers and fruit and even then it might be a tough call.  I too find lowreyana slow but with amazing powers of recovery. I had one rot out. After two years there was no movement so I took the pot off and threw onto the compost heap with the roots in full sun. A year later, your guessed it, it starts to push a new leaf and is now a healthy plant again!

Yep Richard, your input matches my own observation quite! I guess that, however subtle the diffrerencies are between the Hawaian Pritchardias, they become apparent when plants are exposed to extreme yet not overall deadly conditions.

I have a lowreyana seedling that just went into the ground a couple weeks back. Looking forward to seeing it's growth; I like the coarse, wavy blade look of yours. It's similar in appearance to the remotas I've seen. I would have told you a few weeks ago that remotas seem a bit more cold hardy, but the cold snap of the past 3 weeks has dispelled me of that idea.

Pritchardias are frost magnets. They seem to be the first thing in the garden to get damaged by the cold.

Luckily they grow out of it fairly quick.

Yeah, those big flat blades are like table tops for the cold to settle on. The more horizontal, the more damage.

      I’ve just planted this licuala sarawakensis out into my garden. I’m in a 9b type climate zone. I planted it under a big Phoenix canariensis in an area that is sheltered between two high walls ( the house on one side and a high boundary wall on the other). 
      Does anyone have experience growing this species outside the tropics.

      Hey I have a real appreciation for the Pseudophoenix genus, I think they are beautiful, all of them.  I would like to know about which one is the most cold tolerant, is it sargentii?  Seems like sargentii is approximately as hardy as a Royal, but much slower growing, which means recovery is more difficult.  If I remember correctly lediniana is the fastest so it might recover from damage better, but if it is less hardy that also means that it will damage easier.  Also it sounds like sargentii var. navassa is faster than normal, but is it more tender also?
      Are these grown with success in 9b/10a areas of central Florida and south Texas where Royals are grown and might experience periodic damage?  If so, pics please!
      I'm thinking about ordering some seeds and getting some going, that way in a few years when I'm able to move to a more blessed climate than Ohio I'll have some going as they are pretty expensive to buy even in small sizes.
      Any input and pics are appreciated!

      The recent 25 degree temps tested the nana for the first time .....
      C. nana putting out new leaf....no damage


      R. excelsa #1 showing burn


      R. excelsa #2 showing burn


      R. excelsa var. "Short and Fat" ...no damage


      R. excelsa dwarf variety.....no damage


      R. multifida ....no damage

      Really surprised at the hardiness of C. nana ..... what have others observed?

      Any experience on the the minimum temps this plant can take would be appreciated. Is their any chance this cycad can take down to 20F in N. Florida?

      I bought my house back in april 2010 and started planting out palms. By june I had planted out this dypsis pembana from mbpalms as a 1 gallon and it grew quickly for the next 5 months. Then a 30 year cold hit dec 15,16 2010, and my yard, a newly contructed house, had no canopy. Two good frosts(you could scrape it off leaves at 10 am) and ~28F with 6+ hrs below 32F on those days doomed many of my young palms which were not established and small. Even Royal 15 gallon and 7 gallon palms died as did a foxtail 5 gallon and two 3 gallon foxy ladies. All of these and more had spear pull. My only zone 10 palm that didn't get spear pull was a leptocheilos x decaryi, it lost all but the spear. So I watched my pembana for a few days and then the spear came out upon pulling. I learned on palmtalk that repeated peroxide/daconil can sometimes help palms recover. I ripped this pembana out of the ground and almost decided to trash it, but I threw it in a pot and began treatment with all my other burned palms, repeatedly applying it every 2 weeks down the spear hole! Many of the others died, but I was stunned to find that after 3 months of warm weather a spear emerged from this palm. Here is a pic of the palm just after the frost events(3rd day?) and in may 2011 with spear emerging.
