Both Parkinsonia
Parkinsonia aculeata vs Parkinsonia florida
These two are not on this page because a keyword tool suggested them. They are here because our own identification model genuinely mistook one for the other, on real photographs, 5 times. We publish the rate, and then we tell you what actually separates them.

Measured on 38,299 openly licensed, research-grade photographs. Full method and dataset.
What actually separates themon the record
| Family | Both Fabaceae. The family does not separate them. |
|---|---|
| Genus | Both Parkinsonia. Congeners, which is why this is hard. |
| Flowering | Peaks in April versus April. Timing does not separate them. (n = 2,401 and 1,081.) |
What we do not have yet: the diagnostic morphological character that a botanist would key on, from a source we can cite. We are not going to invent one. Until we have it, this page tells you the two are genuinely confusable, how often, and what the taxonomy and the flowering data do and do not settle.
