From time to time a topic that comes up on the forum is the need to acclimate new fish being stocked into a pond before actual release. Temperature, PH, etc. changes need to be slowly introduced to minimize stress and maximize chance of survival. What about when trying to introduce new species of vegetation? Is there a way to acclimate them as well or doesn't it matter?
You know the classic PB answer: It depends!
Truly it does depend on water chemistry, type of plant, time of year, etc, etc.
I can say this from my experience this year: Grass can be much more difficult to grow than you'd think. On the other hand, every button bush we planted near or on the shore, including in holes 3/4 full of water, has not only survived but seems to be thriving. They are Bob Lusk's suggestion for cover & erosion control right on the water, so maybe it's not surprising.
