Boraginaceae and Lamiaceae

Echium vulgare vs Scutellaria drummondii

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.

What actually separates themon the record

Family Boraginaceae versus Lamiaceae. Different families, which is a real separation.
Genus Echium versus Scutellaria.
Flowering Peaks in July versus April. If the plant is in flower, timing helps. (n = 7,258 and 210.)

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.
