Delphiniums have long been a garden favorite, but they suffer from relatively short lives and a tendency to "flop." New Hybrid varieties live longer and have a stronger upright habit. 'Dwarf Stars' is part of the New Millenium™ series of Delphinium, which greatly expands on the benefits of hybrids. This series was bred by Terry Dowdeswell in New Zealand to have enhanced heat and humidity tolerance, coupled with the same cold tolerance Delphinium has long possessed. New Milleniums can grow at least as far south as Zone 7, and they also boast excellent form, vigorous growth habit, and rich, vibrant color.
Resistant to deer and rabbits, this variety is also quite mildew-resistant if given full sun and a little breathing room in the garden. Butterflies and hummingbirds flock to its blooms, so give it a place of prominence and enjoy those two seasons of bloom!
'Dwarf Stars' grows 18 to 30 inches tall and only needs to be spaced about 18 inches apart. Plant 'Dwarf Stars' in a sunny or lightly shaded spot in basic (alkaline) soil--if your soil is more acidic, one way to change this is by adding some lime. Delphinium also appreciates some fertilizing--keep applying rich, organic compost all season to produce the finest blooms. Cut back the first flush of blooms quickly to stimulate rebloom.
With good maintenance, 'Dwarf Stars' will produce dozens of unbelievable vivid, cutflower-quality blooms over a very long season! Zones 3 to 7.
