VERBENA

VERBENA

The Verbena genus includes annual or perennial, herbaceous plants belonging to the Verbenaceae family. Many of the 259 species come from the American continent while others are native to Europe where this plant has been known since ancient times. The Romans used it in their sacred ceremonies and it seems that its name means “sacred branch”. There are many hybrid cultivars on sale that derive from genetic improvements. They have flowers of all colours and are generally trailing plants. The modern varieties are creepers and can, therefore, be used to cover flower beds or in hanging vases from which their branches bend down to produce a cascade of flowers. Verbenas prefer full sun exposure, but also tolerate part-shade. They require moist and well-drained soil. A good composition for potting compost is a mix of 80% organic compost and 20% inert material. The plants must be fed every fortnight with a soluble ternary fertilizer added to the irrigation water. Green pruning can be limited to topping the main branches (eliminating the apex), a practice used to stimulate the development of the secondary branches to obtain more compact plants. Verbenas are very resistant plants and, if placed in the proper position, are rarely attacked by disease.
