Although generally perennial, the usually non-flowering shoots of some plants may occasionally all produce inflorescences. These apparently monocarpic specimens can be distinguished from the strictly annual S. eriocarpum by the basally ascending and usually much-branched stems. [H. 't Hart, B. Bleij & V. V. Byalt]
