Vaccinium vitis-idaea 'Red Candy' (lingonberry 'Red Candy') is a compact, evergreen groundcover grown for glossy foliage, spring bloom, and tart, bright red berries. In the right conditions it forms a low, tidy mat, making it useful at the front of beds, along paths, and in small garden spaces where you want an edible plant that also looks good year-round.
Give it an evenly moist, acidic, organic-rich soil that drains well. Peaty, humus-rich mixes are ideal, and a light mulch helps keep roots cool and soil moisture steady. Plant it where it gets full sun to part shade; in cooler climates, more sun generally improves fruiting, while a little afternoon shade can be helpful in warmer or exposed spots.
Because lingonberries have shallow roots and dislike disturbance, avoid digging deeply around the plant once it is established. Water during dry spells, especially in the first season, but do not leave it in soggy soil. Fertilize lightly in spring with an acid-forming fertilizer if needed, and keep weeds pulled gently by hand so you do not damage roots and runners.
Expect a mature height around 8-10 inches, with a slow, spreading habit. The berries are edible and can be used fresh or cooked in sauces, jams, and preserves. This plant is not a lawn substitute and is intolerant of foot traffic, so site it where it can spread without being walked on.
