Most Vic and Sade fans are familiar - at least to some extent - with Panther's Blood. Panther's Blood, of course, being a variety of flower that is popular in the town the Gooks live in. More specifically, it is Sade who tends to grow it. And it is suggested that she is very successful with her green thumb.
Panther's Blood is probably fictional. Paul Rhymer loved to come up with fictional card games, towns, friends, movie titles, movie stars, book titles and foods. But he did not stop there - he enjoyed making up names of flowers: Late Joe Butlers, Kiss Me Georges, Royal Slumps, Blue Doldrums, Zero Zinnias, and Choke Choke.
