Saw the dahlia tubers at Costco yesterday. Nothing remarkable to me but others may be interested. One was Wittemans Superba a red semi cactus flower in BB(6 inches or less) size.

It is a nice dahlia but the tubers do not keep well. It should be noted that they sell small undivided clumps rather than tubers. It's a Dutch thing; something about it being against the law to divide plant clumps and sell them.
