Seed Potato 'Sapphire'
All potatoes can be grown in the soil, in towers and grow bags. In the case of indeterminate potatoes, they produce their crop along their growing stem, just like tomatoes; the only difference is that tomatoes grow above the soil, fruiting along the exposed stem upward; while potatoes crop below the soil, so the stem must be continually covered up in order to produce viable tubers. These are often your most prolific, late harvest varieties needing around 90-120 days to reach maturity.
