Summary Starch contents of rhizomes of Anemone nemorosa L. and Aegopodium podagraria L. were measured enzymatically. The results were compared to the developmental stage determined weekly. Minimum starch contents were measured few weeks after the begin of the growth period, then the starch contents increased during leaf expansion to reach its maximum immediately before the yellowing of the leaves. During the yellowing starch contents did not increase further due to rhizome growth. Anemone nemorosa had a higher starch content than Aegopodium podagraria. This can be explained in context of the different growth strategies of the plants. The first species follows the dominance strategy of growth, which allows the storage of excess carbohydrates. The explorative growth strategy of Aegopodium requires the consumption of all reserve carbohydrates in spring.
