    Relatively compact in habit, this stout delphinium is now widely grown by cut-flower specialists, because of its ability to bloom so quickly after it has been transplanted. It is however equally useful in the border, providing magnificent colums of colour for several weeks from early summer.

  • Garden care: Protect young foliage against slug and snail damage in spring. Stake with bamboo canes in mid-spring, before the flowers appear. During the growing season, apply a balanced liquid fertiliser every 2-3 weeks and wearing gloves cut back the faded flower-stems to a flowering side-shoot to encourage repeat flowering. At the end of autumn cut back and compost the faded flower-stems.
