Dichondra carolinensis vs Trifolium repens
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.

Trifolium repens
How often our model gets it wrong measured, not estimated
| When the plant was | The model said | How often |
|---|---|---|
| Dichondra carolinensis | Trifolium repens | 3 of 20 (15%) |
The confusion runs one way only. The model mistakes Dichondra carolinensis for Trifolium repens, but not the reverse.
Measured on 38,299 openly licensed, research-grade photographs. Full method and dataset.
What actually separates themon the record
| Family | Convolvulaceae versus Fabaceae. Different families, which is a real separation. |
|---|---|
| Genus | Dichondra versus Trifolium. |
| Flowering | Peaks in March versus June. If the plant is in flower, timing helps. (n = 201 and 21,913.) |
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.
