Rubus idaeus ‘Niwot’ is an everbearing black raspberry bush, remarkable for its double harvest and intensely sweet flavor. This vigorous, bushy raspberry produces abundant clusters of firm, juicy, and aromatic purplish-black fruits, perfect for fresh consumption, jams, and desserts. Its first fruiting appears in summer on the previous year's canes, followed by a second harvest in late summer on new shoots, thus extending the season in the vegetable garden. Its bright green foliage highlights its dark fruits and attracts pollinating insects, promoting biodiversity in the garden. Ideal in rows, as a fruit hedge, or in a food-producing bed, Rubus idaeus ‘Niwot’ captivates with its hardiness, productivity, and distinctive character.
