water hyacinths are classified as invasive species in California and shouldn't be treated lightly. Also I think they're illegal to sell/trade/have in any outdoor body of water (like ponds). I could be wrong on that last part though because for the life of me every year at the state fair I notice them all in the aquaculture/farming exhibits, also saw someone selling them at the flower and garden show too... could be because they weren't expecting and DFW to be patrolling *shrug*
