Do ramps come back every year?

Excuse me, I'm curious about something I've heard about ramps. It's been mentioned that they seem to return or appear every year. Is this true? Could you elaborate on the phenomenon of ramps coming back annually? I'm interested in understanding the biology, growth patterns, or any other factors that contribute to their seasonal reappearance. Is it a predictable cycle, or are there variables that can affect when and how ramps come back?
