The flowers of Sweet Betsy (Trillium cuneatum) are usually purple in color, but some plants have yellow or greenish flowers. Here, we see the purple and yellow flower morphs on adjacent plants. The flowers often have a faint spice-like odor, but you usually have to get your nose up close to the plant to detect it.
It's hard to resist taking a photo of bloodroot, especially when they've just emerged and are so fresh-looking with gobs of golden pollen. The flowers lack nectar, so it's pollen alone that attracts (and rewards) bees and flies that function as pollinators. If the flower fails to attract a pollinator within 3-4 days, the anthers curl into the stigma brushing pollen onto its surface, thereby self-pollinating the flower, a useful backup mechanism since low temperatures and wet conditions frequently reduce insect activity in early spring .
