Yellow false foxglove is a parasitic plant that gets water and nutrients from the roots of various white oak species. It must be grown next to the appropriate oak and form an association with the oak roots in order to survive. Because of this characteristic, we do not grow this plant in pots. When seed is available, it is often included in our savanna mix
. Baltimore checkerspot caterpillars (Euphydryas phaeton
) have been known to feed on this plant, though they prefer white turtlehead (Chelone glabra
). Yellow false foxglove flowers are visited by hummingbirds, bees, and other pollinators.
