Delphinium ‘Guardian Early Blue’

Trial: Annual

Years Trialed: 2003

Delphinium 'Guardian Early Blue'

Good Qualities

Beautiful blue (2); Marginally earlier than ‘Guardian Blue’; Very pretty flower, liked the color better than ‘Guardian Blue’; Good stem strength; Large blossoms.


Poor germination than others in the series, and seedlings were more spindly; Did not perform in Zone 11; Plants and stems never grew very tall, maybe because of weather and fertility; Started too late, no blooms, good healthy plants though; Wimpy transplants, poor germination.


We grow ‘Magic Fountain’ mix and don’t have any this color, better plants in fields than ‘Guardian Blue’; Might do better in hoophouse or field in cooler weather, on 10/24 plants look healthy and some have new flower stalks with flowers about to open, but they are short (Zone 7); For first year this one did good.
