MONTY’S PLANT OF THE WEEK

VER­BENA BONAR­IEN­SIS

Irish Daily Mail - - Gardening -

The pur­ple flo­rets of V. bonar­ien­sis add the char­ac­ter of a rich meadow to a border. It stands up to 2.5m tall in rich soil yet is never dom­i­nat­ing. It is not fully hardy, but in a mild area will sur­vive win­ter and emerge in a bedrag­gled state. It should then be cut back, ready to re­grow. The plants are easy to treat as bi­en­ni­als, sow­ing in May to flower in July the fol­low­ing year, al­though they of­ten be­have like an an­nual, flow­er­ing in the au­tumn of the same year and self-seed­ing in un­likely places. V. bonar­ien­sis per­forms best in open sun­shine, with rich, moist but well-drained soil.
