I have a shrub labeled Cornus sanguinea Arctic Sun 'Cato' and am a bit confused. There is both a yellowtwig and bloodtwig entry in the database with the trademark of Arctic Sun. The general notes on my shrub indicated it would have rich yellow stems with blood red tips and bright green foliage, which it does. Do you suppose there are two separate cultivars of this shrub -- one predominantly yellow and the other red? Or should they be combined to one entry? Neither has a photo attached. I would like to add it to my ATP list and may have a photo to contribute, although the shrub is fairly young so I may not yet have gotten a good shot of it. I assume the 'Cato' is either a specific cultivar or perhaps a sub-something.

Similarly, there are two entries for Arctic Fire, which has a much redder stem. Those may want to be combined as well?
