Grow Tips: Penstemon digitalis ‘Alba’ is a low-maintenance, sun-loving perennial that thrives in full sun to part shade. It prefers medium moisture and well-drained soil, but it tolerates some drought once established. Deadhead spent blooms to encourage a tidier appearance and potentially extend flowering. Cut back stems after flowering to maintain a neat shape and reduce self-seeding. Fertilizing is generally unnecessary in average garden soil—too much fertility can reduce flowering and cause floppy growth.
