About
Verbena corymbosa is a species in the genus Verbena, belonging to the family Verbenaceae, notable for its extended flowering season. In UK gardens it flowers from June to October. The plant suits situations where a prolonged run of blooms is wanted and can be combined with other summer-flowering subjects. Deadheading spent flowers will help maintain the display throughout the season.

In the garden
Verbena corymbosa sits within the genus Verbena and the family Verbenaceae and is valued primarily for its long flowering period, which in the UK runs from June to October. Its extended bloom window makes it useful for sustaining colour across the summer into early autumn. Place Verbena corymbosa where its flowers can be seen and air can circulate freely around the foliage; removing finished flower heads encourages further flushes. Keep a hand on watering while plants establish and tidy stems in late season to prepare for the following year’s growth where appropriate. Avoid blanket statements about soil or aspect unless you can match them to the conditions on your site. Use this Verbena where continuous summer display matters: as part of mixed borders, in containers on terraces or patios, or anywhere a long run of flowering is desirable. Its seasonal performance is most obvious when monitored across the summer months, and the key horticultural marker to expect is a flowering span from June to October.
