This page is a draft, part of our ongoing wild potato project. I’ll probably be adding information to the species pages through 2020 at least, but I’m making them public since they may be useful even incomplete.

Description

This species can survive frosts down to 27 degrees F (-3 C) (Li 1977, as S. cardiophyllum).

Cultivation

Bamberg (2017) found minimal improvement in seed set in this species with supplemental applications of liquid fertilizer at four and seven weeks after potting.

Glykoalkaloid content

Johns (1990) found that the primary glycoalkaloid of this species is demissine and a very low concentration of only about 2mg/100g.  That indicates that S. ehrenbergii is probably as safe to consume as domesticated potatoes.  Some of the accessioned studied were later reclassified as S. cardiophyllum, so the sample size is small.  Caution is always warranted when trying new varieties of any wild potato species.
