Particles are halfway sunken in the plane

Hi fellow artists!

I’ve got a little Particles issue with my plane:

I’ve created a group “Crystals” and used them for the particles for this certain plane. Is there any way to move the particles on the z axis so the crystals don’t “sink” halfway down the plane?

Appreciate all kinds of help!:smiley:

Position the origin of the particle object where you want it to touch the surface.
You can adjust the object origin using the ‘Set Origin’ options in the toolshelf
