What difference does water temperature make on plants? Would a river of hot water have unique foliage?

For instance, if a hot spring produced enough water to have a steadily flowing river, would its surroundings still be similar to normal rivers?

What you will get is a slightly different microclimate and absolute boatloads of animals. In Florida all the manatees cram into the powerplant outflows to stay warm in the winter, and there are parks built around most of them to go manatee-watching. 

Hungry manatees will trim overhanging mangroves once in a while, but land plants are mostly safe from their aquatic gluttony.
