Drought tolerance of Nemesia

Nemesia Vent.

Nemesia is not considered a drought-tolerant crop and requires a consistent level of soil moisture for optimal flowering. The plant is extremely sensitive to the drying out of the root ball, and signs of heat-induced wilting during hot weather are often mistaken for a need for watering.

In the reference 6 varieties crop Nemesia, where this is mentioned in the description.

Standardized indices for drought tolerance have not been determined for members of the genus Nemesia, as this trait is not of breeding significance. Most hybrid varieties show a high dependence on the water regime, with their ability to withstand moisture deficits varying by species. For example, Nemesia fruticans possesses anatomical features, such as a woody base, which allows it to better tolerate short dry periods compared to other members of the genus.

When the moisture regime is disrupted, Nemesia exhibits sparse flowering and premature wilting. In agronomic practice, water management is aimed at maintaining constant soil moisture while ensuring effective drainage, as both substrate drying and overwatering—which triggers fungal diseases—are critical factors for the crop.
