Robin's-Plantain and Robin's nest

4.28.12    Until recently when robins have taken up winter residence, the appearance of robins was heralded as a sure sign of spring.  Likewise,  probably the earliest of the aster family to bloom,  Robin's plantain (Erigeron pulchellus) is a sign of spring and is said to be named for the bird.  Its many-rayed pale violet flowers top a short stalk that emerges from a rosette of basal leaves.  Robin's plantain spreads by runners whereas most other erigerons are seed-sown. 
         While robins are cherished for their cheerful cherr-up, their early arrival, and handsome red(ish) breast, they certainly can't be called fastidious nest-builders.  It will take some cleaning to get this bike back in service.
