This species, sometimes cultivated for its relatively large, attractive flowers, often becomes naturalized in China and elsewhere. Many specimens from China have been determined as Oenothera odorata Jacquin; however, that species, also native to S South America but rarely, if ever, naturalized elsewhere, differs from O. stricta by having narrower leaves, larger petals that lack a red spot at the base, shorter floral tubes, and bracts mostly longer than the capsules they subtend.
