Verbena canescens - Gray Vervain

Verbena canescens – Gray Vervain

Gray Vervain is another one of those small plants likely to be unnoticed, or if it is, to be considered a weed by many.  Here you can see some of the dense hairs that give it its “Gray” appellation.  The small flowers of lavender or purple appear on 3″-6″ spikes from April through October.
