Any ideas? I've also tried watercress (from seeds) with no success what so ever.
Interesting topic and I'm hoping some more people get involved in this.
I don't know that I've heard of anyone using vegetables either way. If I can just use supermarkets I think I recall people growing herbs in planted HOBs, don't remember what kind though. That was in addition to the usual suspects like wandering jew.
I know of two herbs you might be able to find at some Asian markets that I've seen people keeping submerged. Persicaria odorata (Vietnamese coriander) and there is also apparently a form of Limnophila aromatica with 3 leaves at each node instead of the usual 2 being sold in those places.
