During early stages of ontogenesis plant individuals have already formed the adaptive features that are common for adults. S. alpina is defined to be herbaceous semirosette hemicryptophyte with short hypogeogenic plagiotropic rhizome. The rhizome under extreme high-mountain conditions may have deviations from the type of biomorph and acquires rosetteless form with a long branched rhizome that in the whole contributes to enchancing the mobility of the vegetative form.
