Pineberries are a very interesting and delicious cross between the native US strawberry, Fragaria virginiana, and the Chilean strawberry, Fragaria chiloensis. The white-to-pinkish berries taste like a combination of strawberry and pineapple. Our pineberries are the original, old heirloom varieties and are self-fertile, unlike those sold by some others who have created modern hybrids that need a pollinator to produce fruit.
Rumors that they are low producers have not proved true in our garden, where they produce large amounts of approximately quarter-sized berries. The fruits are not as bothered by birds as red strawberries (the birds seem to think they aren't ripe yet), so we get more of them! The berries take on a pinkish hue when exposed to sun. Harvest them when they are quite soft-- unripe berries taste bland, so you will soon discover the best stage at which to pick them.
Because these plants are hybrids, they do not grow true from seed, so daughter plants are the only simple way to propagate them (and as heirlooms, ours are not patented and may be legally propagated, unlike some of our competitors' modern hybrids). They have growth habits and care requirements like the familiar red garden hybrid strawberries. See the Additional Information tab on the page for each variety for generalized care information; however, strawberry care differs between different climates in the US, so for more specific care guidance on hybrid strawberries we recommend that you consult the nearest Agricultural Extension Service for your area (usually affiliated with a major university). Detailed information on growing strawberries from many of these Extension offices can be found online.
