Common Autumn Crocus planted in spring of 1979, under the protection of Lolium perenne, has sprouted in 1980. during the first vegetative year the following plant parts had developed: the mezocotyl, root, hypocotyl, a small bulbotuber below the surface of the ground and the leaf, above it. The blooming spreads over a rather long period of time, reaching its peak in autumn, that is in the first half of October. Self fertilization is to be revealed with the plant - this is mostly allogamous. The plant displays a large variability, inas much as the colchicine content is concerned. The chromosome number in the somatic cells is 2n=38.
