Bush lupine is a tough, fast-establishing shrub that thrives in full sun to part shade with well-drained soil and minimal fertilization. Water deeply but infrequently once established, as it dislikes waterlogged roots. Deadhead spent flower spikes to extend blooming and prevent excessive self-seeding.
