Veronicas, ugh! Grey field vs Bird's Eye vs Slender

They are tough, and there's also V. filliformis, though it's much less common. V. polita has hairs on the stems that are spreading and noticiably a mix of lengths. That's probably definitive.

Generally, V. persica flowers are nearly as large as the leaves, or at least as wide as the leaves, or more than 0.5 cm. V. polita flowers are definitely smaller than the leaves, not as wide as most of the leaves, and under 0.5 cm. V. persica has much longer flower stems, easily longer than the length of a leaf. V. polita stems tend to be shorter and they don't stick out a whole lot above the leaves.

Both of those have leaves clearly longer than wide and fairly densly bunched. If you find something similar with tiny, roundish leaves well spread out along the stem and flower stems like 4 times as long as the little leaves you probably have V. filiformis.

This would be a fun project for a few students to address using quality images and assessing our on-campus observations of this species complex. I will present this post to the students in my Research Methods in Biodiversity class. Thank you for the idea!

Cool. There are a few other Veronicas I've seen around as well. Thyme leaved, ivy leaved, purslane and corn. Germander once. Heath once. But those ones were all a bit easier to tell.
