Ivanetti Dahlia Tuber
Ivanetti is a beautiful dark plum purple ball flower with an interesting metallic cast to the undersides of the petals. Kind of the same color as Diva, in a ball form. They're tough and strong, and for me they bloom 4 inches wide, and very very productive. Not early or late, just right in the middle of the pack with tons of usable blooms in a popular color. Some designers don't want any purple hues when they're looking for darks, so these wouldn't work there, but they'll switch hit for burgundy or plum as you need. A smaller plant, but with lots of stems for cutting.
Ivanetti is a sport of Cornel, along with Cornel Bronze, and Isabel. So she's got those same desirable qualities as they do as far as productivity and form. Such a dream team!
