We are here in Rome for a few days and just visited the Botanical garden today. In the palm garden they had some nice CIDP, very tall washingtonias, sabals, butias, livistonas, a queen, a brahea and some orher varieties but the most amazing was a massive jubaea chilensis.
Very impressive was also a nannorrhops ritchiana that seems to be very old.

The Payneham Jubaea chilensis is a very fertile palm, producing copious amounts of pollen and subsequent fruit.
The Jubaea chilensis at Waite Arboretum appears to be self-sterile, offering tiny quantities of poor quality pollen per inflorescence and up until today, hasn’t dropped a single fruit over the last 2 years despite pushing almost year round spathes.
A while ago, I noticed a limited number of fruit forming on the Waite Jubaea. They were more elongated than the round fruit typically seen on this species.
I picked up the ripe windfall, cleaned the fruit to reveal seed that is again elongated, but also smaller than regular Jubaea.
Due to the previous sterility of the Waite Jubaea, I’m wondering if it has been open pollinated by the various Butia or Syagrus next to it? Plenty of helpful insects/birds around plus Adelaide has been exceptionally windy this summer.
I’ve always thought that seed morphology of a pure cocoid palm species does not change whether it has selfed or received pollen from another species. Rather differences show up in the subsequent F1 hybrid parent.
Could it be seed morphology is an indication of possible hybridisation? Is the Jubaea actually a hybrid? Or am I reading too much into this ?

Not a palm I've seen advertised for sale much here in South Australia, so when I came across these 5 young Jubaea chilensis on Gumtree I jumped at the opportunity.
The private seller grew them from seed and claimed they were around 5 years old. In need of a re-pot, but very healthy.
$100 AUD (£55 GBP/€61 EURO/$73 USD) for the lot!!!
I believe some of them are hybrids (JxB F1) as does Nigel Kembrey.
What do you think?
I soaked them for 3 days (May 3-5) and placed in a 4:1 mixture of perlite and peat moss. 28 seeds split into 5 pots, 1 indoors (around 78F) and 4 outdoors (around 90F day - 75F night). Was expecting to wait 6 months to a year for germination. Surprisingly, the first to sprout was in the indoor pot! Since then I've moved all 5 into the garage (80's-90'sF) and I look forward to more action!
A quick question, when is a good time to transplant it into its own pot with more nutritious soil?
Finally I got ambitious and planed my Jubaea in front of the house.
The soil is not ideal and is mostly rocks...I though in the worst still it should be happier than in the pot...I am not sure if we did something against council to built that brick edging but I just didn't want someone step on it ...and I know it will be very small for this beast if it will make it of course...I will happily remove it then...
It will get almost all day full sun...
what do you think about its fate and future?
