The genius of Tomas Tamberg

Diploid Calsibes on Tamberg 2005 website

(Quoted from Tamberg website) "CALSIBE HYBRIDS (DIPLOID) Hybrids with 2n=40 chromosomes, whose parents can be the species of the Californicae group (Iris douglasiana, Iris innominata, Iris tenax, Iris munzii etc.) on one side and the species of the Chrysographes group (Iris chrysographes, Iris delavayi, Iris clarkei, Iris bulleyana, Iris forrestii und Iris wilsonii) on the other side. Both groups have the same chromosome number of 2n=40, but the chromosomes of both groups are not sufficiently analogue, and the diploid hybrids are, therefore, sterile. - Since they begin to sprout relatively early, Calsibe hybrids suffer especially from late frosts. However, the are not sensitive against permant low winter temperatures."

unplaced: 'Elfenkind' 'Jever Vulkan'

By converting these diploids to tetraploids Tamberg created a new fertile family. See Tetraploid Calsibe Gallery
