brown thumb with Centaurea gold bullion

Hello all,

I've planted numerous gold bullion for several years, and I've been left with 1 that overwintered. I planted them on a hillside in full sun after amending the soil with top soil, manure, and builder's sand for a depth of 2 ft, and only I has returned (last year I must have planted 12). Is it me, or has anyone else had the same problem? Could it be that they aren't hardy to zone 4, or is it a problem with the growing conditions? I can't remember the amount of water we gave them, but we usually water the beds 2-3 times a week in the summer when we notice that some of the plants are in need of a drink.
I didn't plant any this year, but if it's a problem that is easily corrected, I'd like to give them one more shot.
Thanks!
