Are coreopsis usually susceptible to aphids?

Question

My normally healthy coreopsis have a TERRIBLE infestation of aphids – so much so that I have lost the lot. I am even considering Malathion, it is so bad. Are they ordinarily susceptible to such pests? Normal soap and water, applied repeatedly, has not worked.
