Description

Solanum neocardenasii distribution Map note

Solanum neocardenasii (cardenasii for Bolivian botanist Martin Cardenas and neo- because S. cardenasii had been used previously) is a dryland species from eastern Bolivia.  Plants roughly six inches to a foot tall.  Stolons about a foot long.  Tubers small, less than an inch, round to ovoid.  Flowers white.  Berries round, about half an inch in diameter.

S. neocardenasii and its close relative S. stipuloideum appear to be the closest South American relatives to the North American wild potato species (Spooner 2018).

This species has both type A and B glandular trichomes which provide resistance to aphids by entrapment, similar to S. berthaultii (Lapointe 1986).

Subramanian (2017) found that at least some accessions of this species have unusually low dry matter content.

This species has been tentatively classified as critically endangered on the IUCN Red List (Cadima 2014).

Cultivation

I have had no success germinating this species, despite several attempts.  I don’t know if it requires different conditions than S. tuberosum or if I have simply had bad luck.
