Perennial Diversity Perpetual Potato

Package of 4 tubers ,PDPP $9.60

Perennial Diversity represents a decade of growing and selecting potatoes for smaller size and persistance through winter with little cultivation. We started with certain selections of heirloom potatoes, fruited them and then raised their seedlings while selecting over time for small tubers and winter hardiness. For the last several years, we quit cultivating them entirely and waited until fall of 2018 to harvest them.  We offer a 4 pack of four distinct genetically different potatoes with the basic three colors, red, blue and white. Some are fingerlings and some are more round shaped and vary in size from 1-3 inches. This is the mature size of the tuber and not summer harvested. Some of the seedlings may grow larger under cultivation.  Red, blue, white, pink and violet are the colors in this mix.  The textures range from smooth to flakey with a true potato taste like no other-subtle but delicious. You can also purchase true seed of these to test and breed on your own.  We recommend spring planting with this strain. It is not necessary to use heavy mulch to get them to survive. So far few Colorado potato beetles have consumed the foliage. It appears small size favors winter hardiness as well as persistance in the landscape and yes, it spreads.   Available in the fall of 2019 and spring of 2020. 

Seeds available should you wish to further refine this selection:  https://oikostreecrops.com/products/seeds-ecos/vegetable-annual-seeds/perennial-potato-seeds/       Available in the fall of 2019.  Limited supplies on the seeds usually. 

Plant Specs
Genus & Species Solanum tuberosus
Seed Source Michigan, Heirloom
Hardiness -10F to -15F Ground hardiness is unknown but tubers resist freezing fully or partially most winters.
Height (ft) Sprawling to 2 ft. tall.
Width (ft) Sprawling to 4-8 ft. long vines.
Pollination Requirements Diploid selections. Fruitfulness is low usually but not non existent. If you grow them from seed, let the tubers remain in the ground for several years to test 'root hardiness' whether it is thumbs up or thumbs down.
Soil Sandy well drained soil is ideal.
Climate Northern temperate selection but adaptable in other climates. Not tested outside Michigan.
Ease of Cultivation Easiest potato selection we have grown. To some extent this so called 'wild' form is from potato seedlings that appear to resist frost in different ways than we think about root hardiness.
