I hope this is the place to ask this if it's not please tell me

I have for the past 3 years tried to grow the Beautiful Salvia varieties they sell at lowes and other garden centers.
It's mostly the tall ones with the blue spikes like spike speedwell and i believe one had the name Adder in it. I've planted several in orange, blue, white, purple, I find the Tall spikes of flowers very lovely and the bees really love them.

My problem is they will live and grow but only for maybe the spring months then sometime during the summer they develope problems.
The tall stems will begin to get black spots down just above the root section it will then spread a little ways up the stem until the plant begins to die within a short while the whole plant is dead.
I have tried not watering and watering and insect killer sprinkled around the plant but nothing works :(
I really would love to have these in my garden i had one survive for a couple years once but it died the same fate as the ones i planted last year and the year before.
Any suggestions or comments would be very welcome
