Verbena 'Purple Haze' belongs to the genus Verbena within the Verbenaceae family, a group that includes around 150 species ranging from annuals to herbaceous or semi-woody perennials. The majority of species are native to the Americas and Asia, while the European representative Verbena officinalis is native to Europe. Flowers in the genus are small, five-petalled and typically borne in tight spikes; cultivated varieties are available in blue, white, pink and purple tones. Plants of this genus usually show opposite, simple leaves which are often hairy in many species. Flowering in the UK for this cultivar runs from June to October, so expect displays through summer and into autumn. Forms within the genus differ in lifespan—some behave as annuals and others as perennials—so check the specific plant label when choosing stock. Choose plants labelled as the cultivar you want and allow their flowering spikes to develop fully; the long UK flowering window makes them useful where prolonged colour is required. For gardeners tracking seasonal interest, the most reliable indicator of performance with Verbena 'Purple Haze' is the duration of its flower spikes, which carry colour from June right through to October.
