All honey trees are the same. To see what the likelihood of each Pokémon appearing on a tree is, go to http://bulbapedia.bulbagarden.net/wiki/Honey.

This is a common misconception - all honey trees are the same. There are no Honey tree groups.
You slather Honey on a yellow tree (called a Honey Tree). Come back 23-23 1/2 hours later and "talk" to the tree (press A while facing it). Hopefully a Munchlax will appear, but other Pokémon are much more common, such as Combee.
On a honey tree, which appears as a yellow tree. you spread honey on it and wait aboout 2-24 hours. if the tree is shaking, you will have a Pokemon, whoch might be a burmy. and a trainer outside jublife city has 1 as well its his only Pokemon and youre welcome =)
It's Aipom, and you can only catch Aipoms on Honey Trees in Groups 1&2.
Slather Honey on the yellow trees. Munchlax has a 1% chance of appearing, and Heracross has a 4% chance. I recommend slathering Honey on every tree you see, waiting 6 1/2 hours, and checking all the trees.
