Foliage placed under landscape

I have a tessellated and displaced Landscape. I wanted to apply some foliage/scatter meshes via the foliage tool.
But, since some of my landscape layers are displaced a lot more than others, a lot of the foliage meshes spawn under the displaced geometry.
If I adjust the min Z offset, then some of them spawn floating above the less intensely displaced layers.

Is there a way to take the landscape’s displacement into account when placing foliage meshes?

did you ever find a solution to this?
