Blue Honeysuckle
Blue Moon Honeyberry is a late-blooming Lonicera caerulea variety bred for cold climates, hardy from zones 2, 8, that produces abundant crops of striking light-blue, tube-shaped fruit with a flavor somewhere between blueberry and blackberry. This low-mounding shrub develops soft, velvety bright-green foliage and thrives in maritime climates where its late bloom timing helps it avoid spring frosts. The berries demand patience, the skin turns blue well before they're actually ripe inside, but waiting for that purplish interior reveals truly flavorful fruit worth the restraint.

Blue Moon stands out for its unusual tube-shaped berries and remarkably cold-hardy nature, making it one of the few honeyberries suited to far-northern gardens. The foliage is uncommonly soft and velvety, giving the plant ornamental appeal beyond its fruit production. Its late-blooming habit is a genuine advantage in frost-prone regions, and the flavor profile, a hybrid character between blueberry tartness and blackberry depth, makes the fruit genuinely distinctive rather than merely novel.
Blue Moon honeyberries are eaten fresh, though their unique tube shape and flavor make them particularly interesting for anyone seeking beyond-conventional fruit experiences. The berries' character, a blend of blueberry and blackberry notes, suggests they'd work well in preserves, sauces, or alongside other berries in mixed fruit preparations.
Resist the urge to pick Blue Moon berries as soon as the skin turns blue, this is a critical aspect of growing this variety. Instead, wait until the interior of the fruit looks purplish rather than green; at that point, the berries will be fully ripe and flavorful. The outside color can be deceptively blue while the inside remains immature, so patience and a willingness to cut open a test berry rewards you with genuinely sweet, complex fruit.
Prune Blue Moon lightly after fruiting to maintain its naturally attractive low-mounding form. Remove any dead, diseased, or crossing branches to keep the shrub open and productive. Avoid heavy pruning, which can reduce fruit production in subsequent seasons.
