Thunbergia atriplicifolia, the Natal primrose, is a species of flowering plant in the family Acanthaceae,[2] native to South Africa and Eswatini.

The adjective atriplicifolia is derived from the Latin, meaning that its foliage is similar to that of members of the Atriplex genus.

Thunbergia atriplicifolia is a perennial, sparsely to densely pubescent shrublet reaching up to 4 cm high.

Leaves are sessile or with petioles up to 4 mm long; blade is narrow to broad ovate with acute to obtuse apex and cordate to cuneate base, about 2.5–6.0 x 1.5–3.5 cm; margins are entire or toothed, usually only with two teeth at the base.

[5][6] Thunbergia atriplicifolia is a subordinate grassland species where it grows best in both loam and sandy soil.
