Phytosanitary information

Redshift is a Cultivariable original variety, introduced in 2013.  It is notable for heavy yield and excellent flowering.

Culinary Traits

Refshift has no tartness or sweetness and tastes very much like potato.  The cooked texture is soft.  It loses much of its color when cooked, becoming pink or even white.

Agronomic Traits

Redshift plants are among the largest of any variety that we grow, first becoming very tall and then sprawling.  The tubers cluster under the base of the plant and may become crowded, producing irregular shapes.  Tuberization photoperiod is about 12.5 hours, a week earlier than most heirloom varieties.  Average yield is 1.8 pounds.  Maximum tuber length is 5.2 inches and average tuber length is 1.6 inches.  Average tuber count is 36.  This variety produces about twice as many small tubers as large.  Tuber dormancy is longer than most other varieties.

Redshift is an exceptional flowerer with a mid-styled flower, flowering here from June through October.  It is consistently among the top three producers of true seed here, along with Siwash and Wishkah.
