System Information
Operating system: Linux Mint 19
Graphics card: GT 630

Blender Version
Broken:
2.80 (sub 37), branch: blender2.8, commit date: 2018-12-15 22:49, hash: 4b545d1bbf
Worked: 2.79b

Short description of error
In 2.79b one had to rotate the parent particle by 90° on Y in order to have the particles pointing in the right direction. Now, with 2.8, it got worse. Please try the simple gras field setup in both blender versions.

Procedural weed No.1.blend

If you find a way to erect the gras particles as they supposed to be, without applying the modifiers of "leaf", but with the ability to use random rotation around the vertical axis, please let me know.

I can't really reproduce. This was the case in 2.79 too.

Default plane and default cone, set as hair particle replicator in 2.70 gives the same result:

It is silly and impractical that you have to rotate it in Edit Mode to make objects become upright, but I think this is not a bug?

@WilliamReynish Please use my blendfile and tell me if you can do them upright in 2.8. My particles aren't objects but groups (collections).
