Description

Source: leafsnap

Scorzonera hispanica, commonly known as black salsify or Spanish salsify, also known as black oyster plant, serpent root, viper's herb, viper's grass or simply scorzonera, is a perennial member of the genus Scorzonera in the sunflower family (Asteraceae), cultivated as a root vegetable in the same way as purple salsify (Tragopogon porrifolius), also in the sunflower family. It is native to Southern Europe and cultivated as a crop in Southern and Central Europe. It grows on nutrient poor soils, dry pasture, rocky areas, in thickets and on limy or marly soils of temperate zones.

Care Guide

💧 Water Every 3-7 days

Black salsify, originally from Southern Europe, thrives in dry conditions due to its drought tolerance. For optimal growth, water the plant twice a week. It grows best in well-draining soil, which helps prevent waterlogging and promotes healthy root development. Typically, black salsify is cultivated outdoors.

Suggested frequency: Every 3-7 days
☀️ Light Full sun

Black salsify comes from habitats exposed to plenty of sunlight, such as open fields and sunny meadows. It prefers full sun but can also tolerate partial sun.

Ideal: Full sun
🌡️ Temperature 5–35°C

Black salsify prefers moderate temperatures, similar to those people typically find comfortable. It performs best in conditions that are neither too warm nor too cold. The primary problem with high heat is the chance of sunburn, so in summer it’s wise to give some shade to prevent excessive warmth. When temperatures fall, Black salsify goes dormant. If continuous growth is wanted, higher temperatures must be kept during winter. Frost can damage the plant and should be avoided.

Ideal temperature: 5–35°C
