Discussion

An alpine species in its native range, Papaver orientale is widely grown for ornament and sometimes persists after spreading from cultivation. It should be expected elsewhere in the flora.

Papaver bracteatum Lindley, which some authors have included in P. orientale, is similar but more robust, with buds erect, sepals subtended by 3-5 sepaloid and 2 foliaceous bracts, flowers to 20 cm diam., deep red petals with dark basal spot, and capsules to 4 cm. It is widely cultivated and may occasionally escape but apparently does not become naturalized.
