Hope this will help you :

Note : make sure you have load database and upload library either in autoload or in controller

First your form should be like this :

<?php echo form_open_multipart('AddPlant/InsertPlant')?>
    ............
 <?php echo form_close();?>

Your controller should be like this :

public function InsertPlant()
{
    /*here make sure your path is correct*/
    $config['upload_path']          = FCPATH .'assets/uploads/';
    $config['allowed_types']        = '*';

    $this->load->library('upload', $config);

    if ( ! $this->upload->do_upload('plantimg'))
    {
        $error = array('error' => $this->upload->display_errors());
        print_r($error);die;
    }
    else
    {
        //$data = array('upload_data' => $this->upload->data());
        $file_name = $this->upload->data('file_name');
        /*here assuming that your column name for image is image_name, change it not*/
        $data =array(
                'name'=> $this->input->post('name',TRUE),
                'description'=> $this->input->post('description',TRUE),
                'age'=> $this->input->post('age',TRUE),
                'image_name'=> $file_name,
        );
        return $this->db->insert('plants',$data);
    }
}
