Images of one of the N. caerulescens plants at the moment of harvest (12 weeks after germination), and the harvesting strategy along one plant shoot branch. Please note that in the scheme the internodes are shown strongly elongated to visualize better the positions of the leaves. The internodes were counted by carefully opening the plant from the top and labelling the leaves. Since in N. caerulescens the internodes are tiny, it is not possible to see them in the picture
