How do I type in this cultivar. So far I've tried the following
Phlox paniculata Peacock White
Phlox Peacock White
I tried add a new plant and they said it is in the data base. Still it come as not listed or plant not found. I did see two other in the Peacock series. Does any one know how to get to this one?

The entry is here:

Garden Phlox (Phlox paniculata 'Peacock White')

I suspect it was created just before you tried to propose its addition. In that case, the system would recognize it as a duplicate, but the search engine wouldn't find it right away. It takes 15 minutes or so for a new plant to be included in search results.

ZuZu, Thanks for the answer.
