Growth Rate Verbenas generally grow moderately to quickly, and unlike many perennials, bloom well the first season after planting. Some varieties, such as ‘Homestead Purple’, are extremely vigorous. If plants outgrow their assigned space, they tolerate trimming back well. While established verbenas are drought tolerant, performance, bloom, and growth rate will be reduced if they are too dry for a long period. During their blooming period, give them a thorough watering once a week if they do not receive an inch of rain that week. Avoid overhead watering.Verbenas are classic bedding and border plants, popular for their colourful and abundant flowers, produced all summer long. The flowers are also a magnet for pollinating insects, including bees, butterflies and hoverflies. They thrive in full sun, in well-drained soil that doesn’t stay soggy.Important note: perennial verbena will tolerate a light fall trim, but this can delay dormancy and reduce cold hardiness. In cooler climates i would suggest ceasing pruning of perennial verbena plants 45 days before the average first-frost date in your area.Where does verbena grow best?

Verbenas are deciduous, so will die back over the winter months and regrow the following spring. Sun-loving herbaceous perennials make ideal companions for perennial Verbena. Ornamental grasses, Jerusalem Sage, coneflower, fox lily, and Agastache are made for pairing with the tall, delicate stems of Verbena, which provide graceful movement in the slightest of breezes.Perennial types are those which can remain in your garden over the winter months and provide further flowering displays over subsequent years. With these types, including Verbena bonariensis and V.Verbena bonariensis grows to a maximum height and spread of 2. To trim, deadhead the plant in autumn but wait until spring to cut right back down to the base, where new growth will emerge.Leave flowers of hardier types to develop seedheads for the birds and, in mild regions, cut them back before growth starts again in spring. In colder regions, take cuttings to propagate new verbena plants in case they don’t survive winter.
How many years does Verbena last?
Does verbena grow back every year? Annual forms last through the current growing season, while perennial types return the following year. Some are short-lived perennials, lasting just 3 or 4 years. Annual Verbena plants can be cut back in the fall. Perennial Verbena will grow year-round in subtropical climates. In this type of environment, it is only necessary to trim back dead growth as it occurs. In most other regions, perennial Verbenas will need to overwinter.Verbena thrives in full sun with well-drained soil that has been prepared with well-rotted compost. In cold conditions, it can suffer dieback if cut back in autumn, so it’s best to leave the plant until spring and cut back the old growth when you see the new shoots emerging at the base.Does verbena grow back every year? Annual forms last through the current growing season, while perennial types return the following year. Some are short-lived perennials, lasting just 3 or 4 years.Verbenas are long blooming annual or perennial flowers that possess the virtues of heat tolerance and an extremely long bloom season. Many perennial verbenas are relatively short lived, but their vigor and heavy flowering make up for this defect.One of the most captivating features of Verbena bonariensis is its exceptionally long flowering period. Typically lasting from June to September and often extending into October in milder parts of the UK. The tall, stiff, branching stems create an open, transparent shape.

Plant the pricked out seedlings in a more nutrient-rich compost, such as our Plantura Organic Flower Compost.Verbena plants are especially suited to being grown in pots, making them ideal when learning how to grow verbena in pots.Verbena Spacing All Verbena varieties should be spaced 12 inches apart. Young plants will quickly fill in, and they need space to spread out. Upright Verbena will spread about 3 feet while trailing Verbena can claim 3 to 6 feet of space, making them an excellent ground cover.
