There are three species of yellow false foxglove in Connecticut, all with similar flowers. Fernleaf false foxglove is a bushy plant, in contrast to the tall, narrow growth habit of the other species. Other distinguishing marks are very lacy, fern-like leaves and fuzzy, sticky stems. Downy false foxglove (Aureolaria virginica) has softly hairy leaves and stems, but they are not sticky. Smooth false foxglove is recognized by a very smooth stem that is often tinted with purple.
All three false foxgloves always grow near oaks, and they are partially parasitic on the oaks.
