Pet & Human Safety
People: Not researchedPets: Not on the ASPCA lists as we read them
Genuinely unassessed by ASPCA, not cleared. Separate from any chemical toxicity question: UF/IFAS notes this species' frond stems carry sharp teeth/spines, a real physical/mechanical hazard for pets and people handling or brushing against the plant, disclosed here as a distinct caution from the pet-toxicity verdict. For context, ASPCA generally (not universally: see Fishtail Palm) rates true palms non-toxic, though that pattern isn't extended here as a substitute for a species-specific verdict.

USDA 8-11 (UF/IFAS Gardening Solutions): one of the more cold-hardy landscape palms available, well within central Florida and much of the rest of the US. NC State Extension gives a slightly wider range, USDA Zones 8a-11b, corroborating UF/IFAS rather than disagreeing.
- Mature size
8-15 feet tall and 6-10 feet wide, slow-growing (UF/IFAS Gardening Solutions). NC State Extension gives a somewhat wider range, 6-15 feet tall and 6-20 feet wide; shown as a second data point, not a correction.
- Family
Arecaceae (true palm family)
- Where it comes from
Europe: the only palm species native to the European continent (UF/IFAS Gardening Solutions).
