Bindweed

 Some plants get no respect from gardeners. Bindweed is definitely one of them. A member of the morning glory family, it lacks the glorious colors of its more desirable cousins. The heyday of admiration for bindweed was surely around 1900, when its sinuous, curling stems were the epitome of the Art Nouveau style. Nowadays, when a gardener discovers an arrow-leafed stem of bindweed climbing up the roses or asters, they get out the trowel and evict it. But somehow, bindweed persists.
