I've got them in my garden. They have an incredibly soft texture and almost look unripe. They do taste a bit like pineapple.Pineberry is a white strawberry cultivar with a pineapple-like flavor, white coloring, and red seeds
Pineberries come from breeding strawberry stocks from Chile and Virginia. The first commercial cultivation occurred in 2010 in the Netherlands and Belgium.
A pineberry is smaller than a common strawberry, measuring between 15 to 23 mm (0.6 to 0.9 in). When ripe, it is almost completely white, but with red "seeds" (achenes). The plant is disease resistant, but is highly priced, although not very profitable due to small-scale farming, small berry size and low yield. Pineberries are available in the spring and summer.
