As others have mentioned, linux does support VST plugins, as do a number of linux DAWs. But it's worth mentioning that the ecosystem is rather thin at the moment in terms of native VSTs. One solution is to install Windows-based VSTs in a Wine installation and then use linvst, a wrapper which presents those Windows-based VST dlls to a linux host and runs them with Wine. I found it a pain to set up in the first place, and it's hit-and-miss which plugins work in it, but once up and running it actually works smoothly enough, in my experience. (Larger, more complicated VSTs seem correspondingly less likely to work. Of ones that don't immediately work, some can be massaged into working with some tweaking of your wine setup. There's a webpage somewhere with a list of what plugins are known to work and what you need to do to get them to work.) There are other ways of running windows-based VSTs, but that's the one I'm familiar with.
