Neomarica caerulea

Sky blue Walking Iris

This species has turned out to be a 'false' Neomarica. For a longer time it was known already, that it doesn't grow plantlets on top of the flowering stem, hence, it does not 'wander'. Microscopic examination had showed that their cells contain multiples of 8 chromosomes, while a multiple of 9 chromosomes is characteristic for the real Neomarica. At the moment, the proposed name for this species is "Gennov1 caerulea" instead of the name in the title.
According to older literature, this is the most spectacular one of all Neomarica species. Its leaves can grow up to a length of 2m (ca. 6,5 ft.). The sky-blue flowers with a golden brown base reach to a diameter of 15 cm (ca. 6 inch). Unfortunately, my first plants of this species all pined away because of spider mites, dark-winged fungus gnats and root rot; the latter occurred after adding Lizetan Combined granules to the soil.  

On the occasion of our visit in March 2011 to Brazil, Mauro Peixoto gave me a sachet of seeds with the remark that they came from an acquaintance from Rio de Janeiro State and he did not know which Neomarica species it concerned. The germinated seeds and their plants which I had labeled "Unknown Rio de Janeiro" grew up to big Iris plants. In Spring of 2015, two of them were blooming:



According the flowers, it is very likely  G. caerulea.
