Pink flowers clustered at the tips of square stems begin to bloom in late summer.

See Details Below


Pink, tubular-shaped, summer blooming flowers resemble foxglove and snapdragons. Obedient Plant prefers moist, well drained acidic soil, but tolerates a range of soil textures including sand and clay. Full sun is preferable, but they also do well in part shade, which can help keep the soil from drying out. They do not tolerate full shade or soils that are too rich. Occasional flooding is tolerated. In ideal conditions they will spread through underground rhizomes, creating a perky flower patch, which offers a swath of color in the garden. Although not considered historically native to New Jersey, Obedient Plant is native to surrounding states, including New York, Pennsylvania and Maryland. Its native range in the US stretches from Maine to Georgia, and from North Dakota to Texas. In New Jersey it is considered “adventive”, defined as “a species arriving in a new location that may or may not have had help from humans”.  

Wildlife Value: The flowers are attractive to small bees, butterflies and hummingbirds.
