Stomata enable gas exchange for photosynthesis but close to promote survival during drought. Here, Henry et al. provide evidence for a safety-efficiency trade-off whereby plants with greater stomatal conductance under well-watered conditions are more sensitive to stomatal closure during dehydration.
