I have osiria rose seeds. I cannot place them into refrigerator before planting. Can I plant them straight into the ground.
Planting Rose Seeds Directly Into Ground
Osiria is only hardy from zone 7 and warmer. It is a hybrid - has 2 parents - and just like with children, no seed grown plant will have all the features of the parent.
