Summary

This name is a synonym of Hoffmannseggia glauca. Hoffmannseggia glauca is a perennial plant growing from a rhizomatous rootstock with long, underground stems which bear small dark blackish-brown, spheroid tubers ('hog potatoes') up to Icm in diameter. The aerial stems are usually unbranched, up to 40cm tall[1493 ]. The plant is harvested from the wild for local use as food. It is said to have good ornamental value[330 ]. This species can spread aggressively, at least in part, using its underground stems and tubers. It has spread to the Mediterranean and is considered an aggressive grassland weed in its native range[1493 ].

Cultivation details

Hoffmannseggia glauca is native to mainly sub-arid climates and is not very cold-hardy, being able to tolerate short-lived temperatures falling to around -8°c when fully dormant[330 ]. It can tolerate occasional snow cover up to 2 weeks a year[330 ]. The plant is likely to require a sunny position and to succeed in alkaline and heavy soils[K ]. Plants are known to tolerate at least some soil salinity. Established plants are very drought-tolerant [1493 ]. Although many species within the family Fabaceae have a symbiotic relationship with soil bacteria, this species is said to be devoid of such a relationship and, therefore, does not fix atmospheric nitrogen[1309 ]. Cultivation: Ornamental, Wild.
