These abundant, weedy Jacob’s Ladders are often found growing among other equally small, white-flowered annuals like StellariaArabidopsisCapsella, and Cardamine. Unlike many members of those other weedy genera, Polemonium micranthum is a native and not quite as abundant. I certainly would have passed right over it, had I not been on my hands and knees searching for a timid jumping spider. It’s a new species to me!
