CakePHP select default value in SELECT input

Using CakePHP:

I have a many-to-one relationship, let's pretend it's many Leafs to Trees. Of course, I baked a form to add a Leaf to a Tree, and you can specify which Tree it is with a drop-down box ( tag) created by the form helper.

The only thing is, the SELECT box always defaults to Tree #1, but I would like it to default to the Tree it's being added to:

For example, calling
would bring up the interface to add a new Leaf to Tree #5. The dropdown box for
would default to "Tree 5", instead of "Tree 1" that it currently defaults to.

What do I need to put in my Leaf controller and Leaf
to do this?

You should never use select(), or text(), or radio() etc.; it's terrible practice. You should use input():

$form->input('tree_id', array('options' => $trees));

Then in the controller:

$this->data['Leaf']['tree_id'] = $id;
