Meconopsis hybrids in the wild

Just five hybrids have been reported in the wild.

M. ×cookei(punicea × quintuplinervia)
This hybrid is widely grown. It is perennial, producing spreading mats. ‘Old Rose’ is a particularly good form, with quintuplinervia ‘Kaye’s Compact’ as one of the parents. Back-crosses with M. punicea have been made, with the aim of producing plants with the brilliant red flowers of M. punicea, but perennial instead of monocarpic.
M. ×kongboensis(simplicifolia × sulphurea)
M.castanea × georgei
M.regia × paniculata
M.staintonii × taylorii
