Jasoda

Not a lot of help but I can tell you that the group of letters "Jasoda"
does not appear in the 2008-2009 plant finder either as a whole word or
part of a word, so best guess is this is a cut flower variety not sold to
the public and probebly requires computer controled day lengths to get it
to flower
