Hi, welcome to my Foliage Follow-Up post, click on the link to see more posts on Digging, hosted by Pam. Here are a few variegated shrubs-
Morus alba 'Paper Dolls' which is very small still after several years and has shown no indication of trying to fruit, but has had some reverted green branches that had to be removed-
Lonicera nitida 'Lemon Beauty', which is more diminutive that the other nitida's.
And the large-leaved large shrub Elaeagnus ebbingei 'Gilt Edge',
Variegated plants have a special appeal to me, I hope you like them too. -Hannah
