Hi,
If you only need to move the entire ForestIvy object, it's recommended to create a copy of the surface being used and apply the adjustments to that copy. If the ForestIvy should be animated, in addition to the Growth > Baseline parameter, which can be animated, you can also adjust the Growth Level over time. The Rotation and Scale parameters found under the Leaves & Flowers rollout can also be modified as needed. I hope this helps.
Best regards,
