Carex testacea is commonly referred to as?

Carex testacea is commonly referred to as the Orange New Zealand Sedge, which is reflective of its origin and distinctive foliage. This plant is noted for its arching, orange to bronze-colored leaves that provide excellent texture and color contrasts in garden settings. The name not only signifies its New Zealand roots but also highlights the unique appearance of the sedge, which stands out in various landscaping applications, particularly in modern and naturalistic gardens where foliage color plays a key role.

In contrast, the other options listed refer to different plant species, each with their own characteristics and uses. Dwarf Pampas Grass is a more upright grass with feathery plumes, while Black-Eyed Susan is a flowering plant known for its bright yellow blossoms. Feather Reed Grass offers a tall, linear form with delicate flower heads, differing significantly from the low-growing, mound-form of the Orange New Zealand Sedge. This differentiation emphasizes the unique identity and classification of Carex testacea within the landscape horticulture context.
