One of the most adaptable native evergreens we carry. handles wet feet, shade, and neglect while keeping songbirds fed all winter.
Inkberry is the workhorse native evergreen shrub that deserves far more attention than it gets. 'Shamrock' and 'Nigra' are two compact-to-medium cultivars that hold their shape better than straight-species inkberry, with dense lustrous foliage that stays green through the coldest winters. Small black berries develop by late summer and persist through winter, providing reliable food for songbirds when other sources are gone. Unlike many hollies, inkberry handles both wet spots and average garden soils, a genuinely adaptable plant. It spreads slowly by root suckers to form a colony, which makes it excellent for massing along edges or stabilizing slopes. The female plants berry dependably without needing a male nearby, though a male improves fruit set significantly.

Care notes for inkberry holly (shamrock & nigra).
Full sun to part shade in average to wet soils. Can be lightly sheared in early spring if a tighter form is desired, but open natural form is attractive without pruning. Tolerates flooding and poor drainage better than almost any other native shrub. Very low maintenance once established.
Pairs well with these.
