Dimpled Trout Lily

Today I found Trout lily (Erythronium umbilicatum) in full bloom near Clemson, South Carolina. It's both one of the first wildflowers to bloom in spring and one of the most beautiful with nodding yellow flowers that close up tight at night and gradually open the next morning. On warmer days, look for bumblebees visiting the nectar-rich flowers.

Trout lily is a classic example of a spring ephemeral. It emerges from an underground bulb as the soil begins to warm in late winter and dies back in spring as the canopy trees leaf out (thereby shading the forest floor). In a matter of just a few weeks it emerges, leafs out, flowers, sets fruit, and matures seeds. The rest of the year (10+ months) it persists underground as a dormant bulb. So, enjoy this plant while you can as it will soon retreat to its underground refuge.

Spring Beauty (Claytonia virginica)

This low growing perennial is a classic example of a spring ephemeral as it emerges in late winter, grows vegetatively, flowers, and produces seeds all within just a few weeks. The remaining weeks (about 48) each year it persists underground as a dormant plant.

By emerging in late winter, spring beauty (Claytonia virginica) is able to take advantage of the high light levels reaching the forest floor. Once the trees leaf out the forest becomes shaded, after which its ability to photosynthesize and grow is diminished, causing spring beauty to go dormant.

Other spring ephemerals include trout lily (Erythronium species) and Dutchman's britches (Dicentra cucullaria).

The conspicuous pink veins on spring beauty's flowers guide small bees and flies to the nectar at the base of each petal, increasing the likelihood of successful pollination.

Enjoy this plant when you come upon it because next time you visit it's likely to be gone, at least until next year.
