Delphinium ‘Blue Bees’ (Delphinium). An upright, branching perennial with palmate, divided leaves. Loose spikes of single, sometimes semi-double, widely spaced bright blue flowers appear in late spring on freely branching spurs.
They are fully to half hardy and will need an open, sunny position with fertile or rich, well drained soil. In spring remove thin growths from well established plants, leaving 5-7 strong shoots. If flower spikes are removed after they fade, a second flush may be produced in late summer provided plants are fed and watered well.
Useful for cutting.
