White Vervain prefers consistent moisture but can tolerate short dry spells once established. Water thoroughly when the top 2-3 cm of soil feels dry. Avoid waterlogging, as this can lead to root rot.

Reduce watering in winter when the plant is dormant.

Pruning is primarily done to maintain shape and encourage bushier growth. Deadheading spent flowers can promote further blooming throughout the season.

In late fall or early spring, cut back any dead or overgrown stems to the ground to encourage new growth and maintain a tidy appearance.

Verbena urticifolia can be propagated from seeds sown in early spring, either indoors or directly outdoors after the last frost. Cuttings can also be taken from softwood in late spring or semi-hardwood in mid-summer.

These should be placed in well-draining potting mix and kept moist until rooted.

White Vervain is not typically grown in pots and is best suited for naturalized settings or perennial borders. If container cultivation is necessary, repot every 1-2 years in early spring before new growth begins.

Use a well-draining potting mix and a pot that is only slightly larger than the current root ball.
