large woody plant with spectacular red flowers

A likely match for a “large woody plant with spectacular red flowers” is the tree rhododendron (Rhododendron arboreum) , an evergreen shrub or small tree famous for its masses of bright red blooms in spring.

Possible plant ID

• Rhododendron arboreum (tree rhododendron) is a woody, tree‑like rhododendron that can reach around 12 m tall and carries large clusters of vivid red flowers in early to mid‑spring.

• It is native to parts of the Himalayas and Southeast Asia and is known for producing many bell‑shaped flowers together in dense trusses, creating an especially showy red display.

Why it fits your description

• It grows as an evergreen woody shrub or small tree, not a soft herbaceous perennial.

• The plant is widely noted for its spectacular red flowers and even holds a record as one of the largest rhododendrons, which matches the idea of a “large” plant with standout blooms.

If you have a photo or more details (leaf shape, bloom season, approximate height, climate), sharing those would help narrow the ID further.
