It's funny you should start this thread Becky. I've been thinking of you this week as I've harvested my first pods from DD. I crossed it to polys in the hopes that I can get a poly with that pattern.
I've had it a couple of years but bought it as a single fan and last year and it didn't bloom. It has multiplied nicely and this year bloomed well. I didn't count the blooms but I remember pollinating it many times and it set at least 6 pods.
Kidfishing is right when he says all the blooms were perfect. They were very pleasing. Many times when one buys a DL without having seen it "live" the blooms are a disappointment. Not so with DD. I plan to use it for many more years. In addition to polys I want to pair it with some of Dan Hansen's skinny patterns.
I didn't have any rust in the garden this season so cannot comment on it's resistance.
