Bactris setosa is a very common suckering palm on the atlantic plane of my state Paraná (Rio Grande do Sul to Bahia) I dig up a little seedling more then 10 years ago and brought it to my tableland place. Despite it´s habitat being nearly frost free it didn´t suffer any leave damage with the heavier frosts that occured here, and that killed for example mature Chamaedorea costaricana nearby. I planted it in deep shade of the araucaria forest. It´s beginning to fruit now. The fruits are purple and tasty and the nuts also are like a little coconut. Some botanist think the spines were a protection against the extincted giant sloths of the past.

Thanks for posting and educating us about this palm. It's always nice having a palm that's both ornamental and edible in the garden.

Hawaii Island (Big Island), leeward coast, 19 degrees N. latitude, south Kona mauka at approx. 380m (1,250 ft.) and about 1.6 km (1-mile) upslope from ocean.

 

No record of a hurricane passing over this island (yet!).  

Summer maximum rainfall - variable averaging 900-1150mm (35-45") - Perfect drainage on black volcanic rocky soil.  

Nice sunsets!

Thats a nice specimen! They are fairly cold hardy. The one we have growing has tolerated upper 20sF with little damage, same with Bactris mexicana.

I have never seen seeds offered for sale, nor the plants. I wonder why, such hardy and interesting palm!

I took a good look in Harri Lorenzi´s book "Palmeiras do Brasil" and ....maybe this is not a B. setosa but a B. hatschbachii. I sent Harri an email asking him.
