glowed like molten copper every time I passed this spot...
and even though Catmint and Dutch Iris and flowering Onions,
Salvia and Clematis and Sedum
were blooming all around this area...
All my attention was directed at those two leaves.
A few days after first noticing the two leaves my focus broadened somewhat and I noticed very small burnt-orange blooms just across the garden border from the Heucherella. The blooms turned out to be Carolina Mallow [Modiola caroliniana].
Although probably native to South America, this plant has naturalized widely in temperate as well as tropical regions.
If you can get close enough to the ground to see these blooms up close you'll see how beautiful they are.
