Best outdoor backdrop for engagement announcement photos around town?

My fiancé and I are looking for a place around town where we can take engagement photos! We’re looking for somewhere with a lot of flowers/greenery and maybe even a great view of the skyline. Any good greenhouses/gardens/nature centers around town y’all could suggest?? Not to sound picky but we’d prefer it not be too redneck/rustic (Ex: old barns or tractors) because that’s just not our vibe.
