Delphinium elatum 'Sweethearts'
(New Millennium series)
New Millennium Delphiniums are bred by the famous Dowdeswell's Delphiniums in New Zealand.
These F1 hybrids have excellent form, strong stems, and a vigorous growth habit. They need rich, well-drained soil with added manure as they are gross feeders - this will result in healthier, stronger plants.
They can be grown in full sun or partial shade, although full sun may help to prevent powdery mildew. When planting, be sure to set the crown at or above soil level to avoid rot.
Delphiniums must not get warm, very wet feet. Keep as cool as possible with a thick mulch (sawdust also helps prevent slug and snail attack). Since their stems are hollow, they need staking to prevent damage from wind and rain. After flowering cut each flower spike down to 5 cm above ground; reduce water, gradually increasing again when new growth begins. Semi-double flowers.
