I suggest you write to the council and state what happened. Make clear what
damage was caused and what exactly you expect the Council to do. Presumably
you want financial compensation for the plants. If so, let them know how
much you want.

Remember it's not the cost of the seeds or plants that went into the
garden, it's the cost to get you back where you were. Flowers will be
cost of suitable replacement (but don't use it as a way of improving the
garden or stocking up on expensive stuff). Herbs you'll have to buy new
plants, veg you may put a sum in for lost crops if you don't feel able
to eat them - mentioning you are gardening on organic principles would
be sensible here. But as Mark says, don't over-egg it. If they think
you're trying to make a profit over the incident they'll turn you down
flat, and it will cause you no end of a hassle trying to get anywhere.
