You won't find any waterfalls in the Jacksonville/St. Augustine area. It's flat, flat, flat. You won't find much in the way of waterfalls in Florida, period. You may find some runoff areas in the central part of the state ( where there are hills ), but there's not much in that department. As for wildflowers, you might try these parks: Amelia Island, Big Talbot Island, Anastasia State Park, Ravine Gardens ( in Palatka, about 30 miles south of St. Augustine )
Here's a link you might find helpful:
By the way, Jacksonville itself ( otherwise known as JAX ) has very little going for it - unless you love strip malls, and peaceful downtown solitude on a Saturday afternoon.
