Survives zone 5 through 9

Harvest calendar

Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

Also called highbush huckleberry — unusually widespread for a Vaccinium, native across some two dozen eastern US states. Unlike most blueberries, the fairly large fruit ripens through green, pink, dusky purple or brown rather than straight to blue-black; edible but somewhat astringent, more valuable to deer and other wildlife than as a dessert fruit.

Spacing

200 cm (79 in) apart — about 4 m² (43 sq ft) per plant

Leaf shape

Simple, elliptical to oblong or ovate, 2.5–7.5 cm, entire margins

Root system

Shallow and fibrous, almost entirely in the top 30–40 cm, and unusual in having few or no root hairs — the plant relies on ericoid mycorrhizal fungi for most of its water and nutrient uptake instead. Two practical consequences: it dries out fast and wants steady moisture, and it resents cultivation around the base, so mulch rather than hoe.

Fruit description

About 1 cm, ripening green to pink to dusky purple or brown, somewhat astringent

Propagation

Seed after cold stratification, or semi-ripe cuttings in summer, which root less readily than most Vaccinium. Not a plant to move once established.

Pollination

The flowers hold their pollen in tubes that open by pores at the tip, so it is shaken out by bees that vibrate the anthers — bumblebees and solitary bees do this, honeybees largely cannot. Measured, and unusually strict: bagged flowers set no fruit at all, while flowers worked by buzzing bees set up to 68%. Many populations are outright self-incompatible, and the main pollinator is a specialist solitary bee (Melitta eickworti). One plant on its own is an ornamental, not a crop.
