| Neutral | On Dec 7, 2003, palmbob from Acton, CA (Zone 8b) wrote: This is an attractive but intensely spiny palm, usually only grown in the US by palm enthusiasts. This South American native has a nice, ringed trunk, and gracefully arching leaves with long, wavy, premorse leaflets closely spaced along the leaf. However, the spines make this beauty dangerous as they are long (2-3") and so sharp they penetrate leather gloves effortlessly. I had one in the greenhouse for 6 years and rarely failed to get stabbed even though I would try hard to avoid it. Fortunately it eventually suffered from a hard freeze in the cold frame and that was the end of my worries. It could have never survived in the ground in my 9b climate anyway. |
