obedient plant
Low-Frequency / SpecialistFormal / Horticultural / Gardening
Definition
Meaning
A common name for a perennial flowering plant (Physostegia virginiana) known for its unique characteristic: if its flower stalks are manually bent or twisted, they will temporarily remain in the new position before slowly returning.
A garden ornamental native to North America, valued for its tall spikes of tubular pink or white flowers and its ability to 'hold a pose', which inspires its name. It is sometimes called 'false dragonhead' due to its flower shape.
Linguistics
Semantic Notes

Common Mistakes
