Dark colored teeth reminds me of Johnny Depp's character in 'Pirates of the Caribbean'! Yuk! I think it's certainly possible. Both dark edges and toothy edges exist, so it should be possible to combine the two.

Chicken fat would be different. Chicken fat is a glistening, yellow gold, at least till it gets rank. I think the metallic edges might be a better description.

Nina - you read my mind. I was just discussing this with my husband. I'm going to work on it this season-ordered some teethy guys to work with....

Chris,
thats great! We'll have to compare notes. I am thinking that Meet Joe Black and Gavin Petit have such great dark edges and I have them both, I'm going to work with them a bit. They both were super performers their first year here in my SE PA Garden. MJB bloomed for a couple months. And Gavin rebloomed as well. What dark edged DL's do you think might help our endeavor?
