The urge to plant up a pond with who knows what from who knows where is always an interesting challenge.
You may waste slow growing ornamental plants which just do not have the robust growth rates to cope with the carnage rates of a native planting, or at the other extreme you may regret planting devestating cattails, lotus, odorata waterlilies, spatterdocks, each capable of crushing a pond with their amazing growth and reproduction rates.
Starting aquatic plants off in small nursery and you can choose to phase in those plants which strike a happy balance between coping with local grazing and doing something to look forward to, with less of the risk of giving space over to stuff you regret
