# Cutting Back Mexican Primrose
Mexican primrose (Oenothera speciosa), also known as the Mexican evening primrose, pink or showy evening primrose, pink ladies or pink buttercups, is a spreading, herbaceous perennial. The plant has an informal appearance and produces pink flowers, which measure about 2 inches across. The flowers appear in large numbers throughout a long bloom period. Mexican evening primrose grows in U.S. Department of Agriculture plant hardiness zones 5 through 8 and benefits from occasional pruning to keep it attractive and neat.

1
Trim off spent flowers and seed capsules as they appear to encourage continuous, vigorous blooming. This trimming can also help to curb the spread and sprouting of seeds if you do not want to risk having seedlings and new plants appearing in the area.
-
2
Cut the Mexican evening primrose back to ground level whenever the foliage looks unsightly or ragged, which can happen if the plant is severely affected by pests or diseases.
-
3
Cut the Mexican evening primrose stems off at ground level in late summer or early fall after blooming has finished or cold weather kills the stems back. Alternatively, you can wait and cut the stems back in early spring before or just as new growth is emerging.
