Chamaedorea radicalis

Took some pics of my C. radicalis, not the best since it was only 52F, 95% humidity, cloudy and it was getting dark.

More.... The one on the cement bench I just dug up and want to put inside the unheated greenhouse to give it extra growth and then put in a new area of the garden like the patio area.

Last of the bunch... one of the most hardy feather palms out there. Thanks for looking.

What temperature would you say these get really unhappy at?

Low 20F I cover them up, mine have dense overhead cover above and other bushes in front of them to block cold winds... they gone through 15F with blanket on top. They always grow back if they do get damage. Amazing little palms.

The only time I have bad damage is from heavy wet snow that break the branches off. 2" or more can break them, they always recover.  You still have snow, wow, hope it melts soon.

I kept mine in the ground for two winters in the Oklahoma City area, where I got a pretty good idea of when they get unhappy. Mine was planted in a bed on the North West side of my home, but it was in a corner with a brick wall behind it, the front porch on one side, and a sidewalk on the other. With that in mind it only seemed to get damaged after temps got down the 10F to 12F range, though it had overhead protection during snow.

It also has an interesting habit of looking kind of sad but not brown right away. Its fronds tended to brown slowly one by one as we approached spring...at which point it seemed to grow a new frond at about the same rate the old ones died. It never seemed to have more than 6 fronds or less than 3 at any time.

Here it was in June and July 2016. I dug it up when I moved, but I haven't decided yet if I will put it in the ground again or keep it in a pot.

Ben looks really good .... I try to grow mine in groupings to make them seem fuller.

Yeah I plan on these being understory up close to the warm concrete of my house. Will circus tent for events like this current one for sure.

Last year I had several out completely unprotected versus two lows of 19, 36 hours below freezing, all started off by a round of freezing rain.   They had zero damage, while mature washy robustas in the area were completely defoliated.   Mine just saw a dry 18 degrees last week unprotected, with zero damage again.  Wish I could tell you where they start to see damage, but mine seem to not care what is thrown at them.

Anything under 15 is where they start to burn to one degree or another.  Add wind and precipitation and your results may vary.  In every instance I have found Radicalis to be more cold hardy than microspadix as the later will have outright stem death at 15F.

I really like this small palm. This is maybe the most cold hardy crownshaft palm species.

I too like these palms, have a bigger single and a few grown from seeds received by DD. Maybe in two or three years I will try one in a very protected area close to the house.

Chamaedoreas are one of my favourites.

This gives me hope for growing them here. Been almost a month since I put them in the planter hope they start sprouting soon.

Almost been a month since I put the ones you gave me in soil, about 2.5 to 3 weeks since I put the heater underneath. Hoping for a 1 month sprout but planning on up to 6 months seeing as its my first time germinating palms. I keep them moist with spraying water twice a day ( the sun in the day helps dry up the soil a bit and also helps heat the pod. No temp monitor in there as its pretty wet, but the house is a steady 70F and the pad advertises 10-20F raise in temperature and the sun during the day helps too!

Thanks Tracy, a new friend of mine that just moved here from Mississippi 6 months ago said he can't believe how green it is here in the winter time.... Can't wait for him to see all the flowers in bloom come spring. 

Here in the PNW we can grow a lot of plants from around the world that other parts of the county can't. Going nursery shopping here is quite the experience with so much to choose from. I'm sure it the same for you. My goal when designing this garden was to have it be really green all year since it so grey and rainy in winter. And to have flowers throughout the year that also provide food for wildlife. Thanks for the comment.

I don't understand the weather in the US.Here in the winter its in the 50's during the day and 40's during the night.Of course it can be a bit colder or a bit warmer,but those are our averages.Meanwhile u guys go from highs in the 70's to snow,what the heck!!!?!?

And that's the exact same reason why palms that are hardy in parts of the US cannot survive the same temperatures here. Because here, when it is cold it stays cold.

Snow & this cold is a freak event here. In a normal winter we get a average of 7-10 nights where we drop below 32F and on those nights we rarely get below 25F.

Yeah life on and around the fall line is hell in winter. 60s and 70s on day and 20s and 30s the next. The good thing is 99 out of 100 snow events melt the next or same day.

Nursery was 8f wednesday morning, then back to 74 & 73 over the weekend.  Lows were in the 60s. Last January we went dropped from 74 to the 20s in four hours.

Incredible,our record low is 15 degrees fahrenheit,but if that happens we are fried,because we are not going to see temps above 40 for a loong looong time.

snow here falls once every 8-12 years,but the temp is from 30-34 when it falls so it damages almost nothing.

Yeah but also their record lows are much worse than ours.I am in north coastal Croatia 9a,but our record low is 15 degrees f,meanwhile their record lows in 9a zones in alabama,louisiana,florida,texas etc. are usually below 10 degrees.

2016/2017 winter we were in OC Maryland and it was 70s all weekend with lows in the 50s, we were swimming in the ocean (yeah it was actually warm enough) then it dropped to the 30s in no time flat. Felt like an hour or 2 is all it took.

Those are our normal low temps, but we can receive arctic blasts courtesy of Canada that can dip us way bellow that. Rare to drop bellow 15-18F depending on where you're located, but as this winter has shown us it certainly can go much further bellow average. We saw a low of 3F this winter! I think the last time it was this cold was in the 80's, and of course now we have been in the 60s with lows in the 40s. But we are going to have 1-3 days in the 10 day forecast that may see lows in the mid 20s and highs in the low 40s. Its very normal for us to swing 20+ degrees in a day. 

 

We kind of have a similar cycle that yall have and that is for blizzards. Once every 6-10 years we get hammered with a blizzard and get 12-18in of snow dumped on us in one storm!

I'm on the West Coast of the USA, My winters are cooler and pretty much cooler all year compared to the South East USA.

Dec-Jan. for me...Highs are 40's-50's, Lows are 30's-40's.

85% of the weather here is marine, with 15% being continental. That 15% means in winter it gets colder, and hotter in summer. I do have high humidity all year.  55 inches of rain per year, mostly fall/winter and dry in summer. East coast mostly dry in winter and wet in summer. 

My low this winter was 25.5F in December and so far 29F in January. No big arctic blast from Canada for me this winter so far that is. Last year It got down to 21F, the year before 19F. I'm in one of the few 8a areas of my state of Washington, most are 8b.

The central part of the North American continent is one of the most wide-open expanses of land with no mountains from north to south, anywhere in the world. The crazy temperature/weather swings can be both fun and really frustrating depending on the day...

I can imagine some serious rotting happening on plants if the weather goes from freezing to warm in a day,but for us humans It's nice.Our winters never go above 60 degrees.I am jelaous.

Well that not really true, at least not for southern Croatia.  Here in Dubrovnik it can go up to 20C sometime in winter. Even minimal temperatures can be around 15C during winter (during southern winds weather, or rain).

Well I sure hope swings like this don't raise rot chances. We often swing 20F+ in a normal winter day, and like we have seen the past week swings even further! We have been in the 60s and even low 70s with nights from mid 30s to mid 50s. We go from days like that to days with lows in the 20s and highs in the 30s or 40s. Didnt seem to bother my chamaerops humilis last winter, but the swings also weren't as large. 

 

This being my second over wintering of palms I have seen lots of damaging effects from roasted fronds (Trachycarpus), complete defoliation (Livistona) to spear pull (Trachycarpus and Chamaerops). But Im 100% sure it had to do with the extreme lows mixed with what felt like record setting length of cold/bellow freezing.
