Asa candidate for the dark energy, the hessence model hasbeen recently introduced. We discuss the critical points of thismodel in an almost general case, that is for arbitraryhessence potential and almost arbitrary hessence-background matter interaction. It isshown that, in all models, there always exist some stablelate-time attractors. It is shown that our general results coincidewith those solutions obtained earlier for special cases, but someof them are new. These new solutions have two uniquecharacteristics. First, the hessence field has finite value in thesesolutions and, second, their stabilities depend on the second derivativeof the hessence potential.
