 Delphinium elatum
Blue Delphinium
Delphiniums are bi-annuals that are normally planted in
the fall and bloom the following spring in colder climates. The Guardian series
of Delphinium is an F1 hybrid that will bloom the first year allowing them to be
grown as an annual in milder southern climates. This F1 produces more uniform
growth and faster flowers than most open pollinated Delphinium varieties. The
low mounding clumps of deeply lobed foliage sends up showy 4-6 foot flower
spikes of double, bright blue flowers with white centers. ‘Guardian Blue’ is an
excellent cut flower and makes an exceptional specimen in any perennial border.
Cut back old flower stalks to encourage a second bloom. This perennial can reach
24" tall.
