Despite the wealth of available germplasm amongst the Iridaceae,
only 40 species from 12 genera have been micropropagated (Ascough
et al., 2009). George (1993) and Ascough et al. (2009) presented
extensive summaries of bulbous and cormous species which were
micropropagated in vitro, and subsequently successfully hardened-off
and established ex vitro. According to Ascough et al. (2007), root and
leaf explants of Watsonia spp. were incapable of shoot regeneration
