Fernleaf Yellow False Foxglove

Fernleaf Yellow False Foxglove
Aureolaria pedicularia

This species is cool in that it is a hemiparasite, which means that it gets some of its nutrition from another plant, namely oaks.  Its roots attach to the roots of an oak tree and suck out the juice.  It doesn't hurt the oak tree.  All of the Aureolaria species, i.e. the yellow false foxgloves, are hemiparasites on oak trees.  You won't find any in a garden anywhere unless it's shaded by an oak.

According to the botanists, this species differs from other Aureolaria species by its bipinnatifid leaves, pinnatifid calyx teeth, and glandular hairs on its stems and pedicels.

Note the bipinnatifid leaves
