Stunning lagoon blue flowers, each with a white fleck, appear in upright columns from early summer. 'Persian Slipper' looks fabulous when woven through mixed or herbaceous borders, where it will add height. The flowering spires have a spicy, peppery scent and look fabulous when planted with purple and pink flowering early summer perennials such as Geranium and Astrantia.
How to care for Lupinus Persian Slipper (PBR):
Plant lupins in full sun with well-drained, slightly acidic to neutral soil, avoiding heavy clay. Water regularly while establishing, but once mature they become more tolerant to dry conditions.
Stake tall cultivated varieties with bamboo canes in spring before flowers appear, and remove faded blooms to encourage a second flush. Mulch lightly in winter to protect roots, and watch for slugs and snails on young growth.
