A number of species replace corms every year by growing a new corm. This process starts after the shoot develops fully expanded leaves. The new corm forms at the shoot base just above the old corm. As the new corm grows, short stolons appear that end with the newly growing small cormels. As the plants grow and flower, they use up the old corm ...
Crocus (/ ˈ k r oʊ k ə s /; plural: crocuses or croci) is a genus of seasonal flowering plants in the family Iridaceae (iris family) comprising about 100 species of perennials growing from corms.

It is a member of the botanical family Colchicaceae , and is native to West Asia , Europe , parts of the Mediterranean coast, down the East ...
Chromosome doubling could in principle also create a fertile hexaploid plant. Such a change may be possible via colchicine. [23] Corms of saffron crocus should be planted 10 cm (4 in) apart and in a trough 10 cm (4 in) deep. The flower grows best in areas of full sun in well-drained soil with moderate levels of organic content. [24]
The plant blooms annually around the beginning of the rainy season. The flower bud emerges from the corm as a purple shoot, and later blooms as a purple inflorescence. The pistillate (female) and staminate (male) flowers are on the same plant and are crowded in cylindrical masses as an inflorescence. The top part is responsible for secreting ...
Crocosmia (/ k r ə ˈ k ɒ z m i ə, k r oʊ-/ [2] [3]), also known as montbretia [4] (/ m ɒ n ˈ b r iː ʃ ə / [5]), is a small genus of flowering plants in the iris family, Iridaceae. It is native to the grasslands of southern and eastern Africa , ranging from South Africa to Sudan .
Crocus ochroleucus is a herbaceous perennial geophyte growing from a corm. The corm is small, surrounded with membranous brown tunics. Each corm produces 4-6 leaves, appearing together with flowers, strongly canaliculate, 1.5–2 mm wide. Basal spathe often surrounding numerous scapes. Floral spathe diphyllous, partly enclosing a long tube.
