Flowering stock

Question

Is there anyway you can tell which stock seedlings will turn out single?

Answer 1

Planting a single bloom variety should yield mostly single flowers; the double bloom varieties always have a percentage of blossoms that come out single, but some varieties have a smaller percentage than others. There's some indication that the double-flowered seedlings are sturdier and lighter in color than then singles.
