Troy’s Ropalostylis thread got me thinking about the Chatham Island form. The photo of me with the huge one is from back in 2010 or thereabouts. The next one is taken today with my 2nd generation offspring grown from seed at my home. I planted it in 2012 from one gallon pot.

Yes they are more robust and seem more durable. Here’s another photo of the one in my former home

This was my R. Sapida the year it got hit with the Death Ray of 2018 . Within two years , it was dead. The heatwave also killed one of my Howea Foresteriana. I believe it would have survived had it had some shade . It was noticeably less robust than the Chatham Island form that I see on this thread. HarryIMG_1296.thumb.jpeg.f2a3a84cfff1a87584305f315b3be503.jpeg

Sorry , this is one of the only pics I could find of the palm. I grew it from a 4” seedling band . IMG_0258.thumb.jpeg.5b17685059fc5ee198892ff51baea941.jpeg

‘Once it got overheated by the heat wave , it did this and died shortly after.🙁 Understandably , I really don’t like this picture. This was two years after the other pic. It was a slow , painful process. Harry

Every palm loss is an opportunity to refine and improve your landscape !   I used to get really upset when a special palm died*,

Lately, not so much,  sort of... "grow or die, whatever" !  :winkie:

* Parajubaea cocoides, 12 feet of wood trunk

Lepidorrhachis, two plants with 30 inches of trunk each

Hedyscepe, 10 feet of trunk below the crownshaft

Prestoea acuminata v. acuminata 30 inches of 4 inch diameter trunk

Geonoma undata, red leafbase from Dick Endt  9 feet of wood trunk

Howea forsteriana,  30 inches of swollen 'elephant foot' trunk, killed after rats chewed off all the fronds, then infection by bacterium or fungus  

Laccospadix, 5 gallon with red flush as strong as a Chambeyronia

Yeah that big July 2018 death Ray was a bummer. 
 

More surprising what it didn’t kill…

How are you sure that original specimen had not hybridised with other Ropalostylis spp?

Darold your Chatham island form has a huge circumference of the crown shaft

Darolds Garden is like a museum for different types of Rhopalostylis.

From my experience the Chatham islands flower at different times to my other Rhopalostylis

This season in NZ.

Chathams have flowered once or twice but the kermadecs haven't started yet. Last seasons seed is just maturing on the kermadecs

Only in NZ does Hedyscepe get relegated to the background of a shot without mention. Amazing!

Well , in retrospect it was my fault . That is in a courtyard that is the warmest spot in our yard. During record heat waves like we experienced in 2018 , it turned into an oven , cooking anything below the roof line . We had three to four days above 105f with very little night time cooling. That is rare for our area . I lost two palms and some lost more . I’m so glad that I didn’t lose more palms. I have several Howea around my house that survived but got their fronds cooked . @DoomsDave calls it “ The Death Ray of 2018” he lost a few palms as well . Normally we have warm summers with nice cooling in the evenings . Our summers average in the low to mid 80f range . The Rhopalostylus grew very slowly in that spot but did ok and looked nice , I had no idea that they were sensitive to our inland summer warmth ( 20 miles from the beach ). The death ray was a fatal blow . Two blocks from me , three other Rhopies met with the same fate. Harry

Yes , since adopting that palm from your extensive collection , it has doubled in size! That is the third frond since it came home with me. From what I’m told , it is a bit more resistant to our inland climate than R.  Sapida . It has cruised through a couple of heat waves already . Perhaps the Chatham Island variety is more hardy as well. The ones posted on this thread look like monsters compared to my old R. Sapida I had. Harry

Reckon you're a couple of degrees warmer than Hobart...we're probably closer to Wellington averages. 

Fantastic looking Hedy and seedlings, great work!
