The berries and leaves on this tiny tree look like they might belong to a pyracantha 

A little whimsical today, but kinda cool too. The whimsy is how tiny these little guys are, and I guess that's the cool part too (I know I'm light years from being a teenager, but somehow cool keeps slipping back into my vocabulary)

I found these photos in a place called World's Smallest Trees

 Another little one. Is it a crabapple?

I don't know how big this one is (no size or variety is given), but clearly it's nowhere near as small as the other two. It looks like another  pyracantha with new berries just forming. They're green now but should end up somewhere in the red to yellow range
