Sorry hazel. Lost this thread. Yes, they should be ok. Just check occasionally to make sure they are damp, not soaked, just damp. They may die back a little but still plant them in the fall. Like I said, they are a difficult plant sometimes.
Hybrid seeds may well not be viable. They also may not come true to colour from parent plant.
Assumptions do nothing but make an ass out of u and me.
We can stick our heads in the sand for only so long before it starts choking us. Face it folks. The pet population is bad ALL OVER THE WORLD!
