This is the 15th year of continuous daily publication for 365Caws. All things considered, it's likely it will be the last year as it is becoming increasingly difficult for me to find interesting material. However, I hope that I may have inspired someone to a greater curiosity about the natural world with my natural history posts, or encouraged a novice weaver or needleworker. If so, I've done what I set out to do.

Oxalis Oregana, Wood Sorrel
Day 171: Shy little Oxalis oregana (Redwood Sorrel) is common in the Pacific Northwest and often occurs fairly densely where it receives shade from Douglas-fir. Its three-lobed leaves resemble those of clover, although on a grand scale, and they are highly sensitive to light levels. When the sun breaks through the forest canopy, the leaves will fold downward in a matter of minutes, opening again when shade returns. The flowers may be white to pink, and may be marked with darker purple "nectar guides." Pollination is performed largely by syrphid flies. All parts of the plant contain oxalic acid and should not be eaten.
