Use a change event, append a span with the text to the selected option:

$('select').on('change',function() {
$('option').find('span').remove();//remove previous selected span
var val = $(this).find(':selected').html();//get the text/html of the potion
$(this).find(':selected').html('<span>Favorite Flower: </span>'+val);//change the text with the option
});

or:

$('select').on('change',function() {
$('option').find('span').remove();
var selected = $(this).find(':selected'),
    val = selected.html(); 
if(!selected.is('option:first')) {
$(this).find(':selected').html('<span>Favorite Flower: </span>'+val);
}
});
