Code base getting large. Decided to get better at GIT...

I am using xCode and decided to move away from xcode git and to SourceTree. I am keeping my code local on my machine but would like to get into the git flow habit. I opened Sourcetree and imported my project. All looks good. 

I did a final commit and initialized GitFlow. But as I move from Master branch to Development Branch to creating Feature Branches, I see the branch names in the log, but I do not see the parallel gitflow colored lines. Is that because my project is local and I am not doing any Pull/Push? or am I missing a setting? 

PS: Using xcode 5. Not sure if related.
