Bonavista was hybridized by Dr. Felicitas Svejda at the Canadian Department of Agriculture. It is a diploid rugosa X chinesis hybrid.
The following of last winters crosses that involve my seedling of Bonavista (Bonavista X OP) have grown at least one foot in height this summer (I consider that these are mature enough to survive the winter):
unknown non rugosa X (Bonavista X OP). Eleven plants.
((Therese Bugnet X OP) X OP) X (Bonavista X OP). Three plants.
(Bonavista X OP) X OP. One plant.
((Delicata X OP) X ((Therese Bugnet X OP) X OP)) X (Bonavista X OP). One plant.
Unknown rugosa X (Bonavista X OP). One plant.
The following seedlings are alive but have grown less than one foot (these may not survive the winter - I have sprayed them with gibberellic acid to give them a boost):
unknown non rugosa X (Bonavista X OP). Two plants.
((Therese Bugnet X OP) X OP) X (Bonavista X OP). Nine plants.
(Bonavista X OP) X OP. Three plants.
