Answer: I found Annabelle Viburnum at Shady Grove Gardens and Nursery in Zionville, NC. According to their website they are "Just 10 Miles from Boone. To get to the nursery take Hwy. 421 NW from Boone 9 miles, to Will Isaacs Road, follow signs 1 mile uphill, then, turn left. For more information call 297-4098".
Hope this information helps!
