Poor Dahlia Tuber Survival

I planted the dahlia tubers some time ago and noted that the survival of the more common strains was very poor while others was excellent.  I've noted these below.

Blue Boy:  Zero survival rate, although the fact that I was working from one tuber that survived the mole invasion last year probably had something to do with that.  I replaced these this year as they're incredible plants and treating them as annuals doesn't bother me if that's what I have to do.

Color Spectacle:  I bought these at Home Depot, and they survived very well.  Some of the splits were given away, one found a new home in a huge pot on the patio.

Sky Angel:  A Home Depot closeout buy some years ago, these tubers perform extremely well.  Every year I split and give the daughters away.

Sun Lady:  Zero survival rate, and the tubers were rich and large last fall.  I replaced these as well since the plants are gorgeous and if they have to be treated as annuals I'm willing to do that.
