Clematis paniculata vs Rubus cissoides
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, 3 times. We publish the rate, and then we tell you what actually separates them.

Clematis paniculata
Rubus cissoides
How often our model gets it wrong measured, not estimated
| When the plant was | The model said | How often |
|---|---|---|
| Clematis paniculata | Rubus cissoides | 3 of 18 (17%) |
The confusion runs one way only. The model mistakes Clematis paniculata for Rubus cissoides, but not the reverse.
Measured on 38,299 openly licensed, research-grade photographs. Full method and dataset.
What actually separates themon the record
| Family | Ranunculaceae versus Rosaceae. Different families, which is a real separation. |
|---|---|
| Genus | Clematis versus Rubus. |
| Flowering | Peaks in October versus October. Timing does not separate them. (n = 1,660 and 253.) |
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.
