Webexample, among herbaceous grassland species, taller species often flower later than shorter ones (Dahlgren, von Zeipel & Ehrle´n 2007; Du & Qi 2010). However, it is still ambiguous whether flowering phenology largely depends on height growth pattern in grassland species, because two critical ques-tions have not been fully addressed.
