•Drought affected the starch (aerial organs) of shade-tolerant more than sun-tolerant ecotype of P. echinata.•Shade-tolerant ecotypes were more sensitive to drought, requiring greater NSC and CWP adjustments.•These responses may hinder plant functioning under intensified droughts. How shade-tolerant...
