I've never figured out if this viburnum is called Cardinal Candy because of its cardinal red color or because the birds just go nuts over the berries. Cardinals are pretty shy but when these berries come into season a little later, they will ignore your approach while they gorge themselves — until their better instincts prevail.
The species Viburnum dilatatum is commonly called linden viburnum because its leaves resemble those of the linden tree (Tilia). The 'Cardinal Candy' cultivar originated about 20 years ago with Indiana nurseryman Rod Henneke (sometimes his surname appears on tags because it's still under trademark protection) when, after a severe (-25 F) winter, he lost all his seedlings save one which he has propagated with great success.
The species is native to open forests and scrubby areas of China, Korea and Japan; it will grow in North America from zones 4-7. Most viburnums are not self-fertile and need a compatible species nearby to assure good fruit but Cotton Candy seems to defy that convention.
Although you don't hear people talk about viburnums very much they are probably the most widely used shrub in American landscapes (second only to boxwood) because landscapers know that with about 175 species and a variety of colorful flowers and berries, fragrance, and good autumn color, they provide a wide design palette and consistent customer satisfaction.
