We are fortunate that our purple (or blue) potatoes have produced both beautiful flowers and fruit (an unusual occurrence, as we understand). The fruit produces true potato seeds, a way to cultivate original potatoes!
The flowers are lovely...
You have to wait until the potato greens dry up and wilt, and subsequently the fruit will wilt. Then you pick the fruit, let it try completely, and wash it with hot water to remove the gel that protects the seeds. Then dry the seeds. When planted the next season, you can not expect a great yield. The seeds are from the original potato, which may not reflect anything similar to the potato sprouts you planted, and will take time to cultivate. But the second year, when you plant those potato sprouts (from the spud, not the seed), you will have a great fresh crop of potato.
We are very excited that we have this potato fruit in our garden, and will keep you in the loop of our true potato seed harvesting and planting progress!
