Wrigleyana is actually the first hybrid involving mirabilis x hookeriana. N. Coccinea was a later remake using different parental forms. Most of those Victorian hybrids deserve more attention than they get.
More on those Wrigleyana (mirabilis x hookeriana) plants: there were hybrids made earlier,N. Stewartii (1879), N. Robusta (1880), N. Lawrenciana (1880), and N. Morganiana (1881). N. Wrigleyana and N. Coccinea are from 1882. We have seen male and female plants of Wrigleyana and Coccinea, but Morganiana is a single female clone. Anyone aware of any of the others still in cultivation?
