Raise your planting scheme up a level with towering Verbena bonariensis. Bobbles of small purple flower clusters are elevated by long, sturdy but slender stalks up to 2m—it's this eye-level interest which contributes to an impressive and professional looking border. You can enjoy the height of this plant, but without having to sacrifice space because it's extremely narrow! RHS Award-winning Verbena bonariensis is a bee and butterfly magnet, drought tolerant and will bring pops of purple to your garden for most of summer. What's more, this purpletop vervain combines well with virtually anything, from dahlias to ornamental grasses.
Verbena bonariensis—common names include Argentinian vervain, South American vervain, tall verbena, clustertop vervain, pretty verbena or just purple top—on its own is very subtle. In big groups or drifts it makes a big impact, and also forms a pretty partial screen, which can be useful for front gardens. This plant loves free-draining soil, but can tolerate most soil types. You can plant Verbena bonariensis in any sunny border or a gravel area, it's a great choice for coastal gardens in particular and returns every year when it's happy in its spot.
This purple top vervain plant is also known under the names: Verbena bonariensis 'Buenos Aires', Verbena patagonica, and Verbena brasiliensis.

Plant calendar
Check each plant’s specifications. Hardy perennials can remain outdoors, while half-hardy and tender varieties should be kept frost-free until the risk of frost has passed.
Plant within a month, preferably sooner. Choose a suitable position, remove weeds and loosen the soil thoroughly, adding compost or well-rotted organic matter where needed.
Gently remove the plant from its pot and plant with the root ball level with the soil surface. Firm gently, water well and add a plant label.
Water regularly until established and whenever the soil feels dry during spring and summer. Feed container-grown plants fortnightly during active growth to encourage healthy flowering.
