•Transpiration regulation during rising VPD is soil texture-specific even in wet soil.•Leaf area and root:shoot-ratio do not consistently differ between soils.•Maximum canopy conductance scales with soil hydraulic conductivity in the wet range.•Plants limit transpiration at lower VPD when their maxi...
