Following Bruce's remark that the song is not called "My Only Jo and Dearie-O" (though the tune is), it occurred to me to look for it as "Thy Cheek is o' the Rose's Hue", which appears to be the right title.  Unfortunately I haven't been able to find a text, but it does seems to be available in two books at present:  Songs of Scotland  (edited by Wilma Paterson) and  Seventy Scottish Songs  (selected and arranged by Helen Hopekirk) -the second book is a lot cheaper!
