Drought tolerance of Gaura lindheimeri

Oenothera lindheimeri (Engelm. & A. Gray) W. L. Wagner & Hoch

Gaura lindheimeri exhibits high drought tolerance due to a well-developed taproot system adapted to growing in nutrient-poor soils and irregular precipitation conditions.

In the reference 9 varieties crop Lindheimer's beeblossom, where this is mentioned in the description.

For this crop, the assessment of drought tolerance is based on water-use efficiency, defined as the ratio of the plant's dry biomass to the volume of water consumed. The plant demonstrates resistance after the establishment period; during this time, substrate moisture status is evaluated by the dryness of the top 2–3 cm of the soil or by visual signs of initial leaf wilting.

The plant's high drought tolerance is directly linked to its sensitivity to waterlogging, making proper drainage critical for preventing root rot. Excessive application of water and fertilizers negatively affects bush morphology, provoking redundant vegetative growth and lodging, as well as reducing natural resistance to pathogens.
