Selected in New Zealand, the New Millennium Delphinium strains outperform all other tall types and offer some astonishingly rich shades. This variety produces tall, stately spires with single flowers in shades of rich royal purple, with a contrasting white “bee” in the centre. The deeply-cut leaves form a medium-sized bushy mound with superior vigour. Stems may require staking in windy areas, best done before they reach 3 feet or so in height. Removing spent spikes right after flowering will encourage repeat blooming in fall. In hot, humid summer regions Delphinium plants do not usually last more than 2 to 3 years. Foliage may become infected with powdery mildew in mid summer; simply cut back hard to encourage fresh leaves or use a preventative fungicide beginning in mid spring. For best flowering use a high phosphorous fertilizer each year, in early spring. CAUTION: Harmful if eaten.
