Southern rockbell

This is 'Hinagikyou' or Southern rockbell??? Honestly speaking, I am not so sure for today's plant. If so, the botanical name is Warlenbergia marginata.







One of my friends said 'The first and the second pictures are the same plant, but the third one shows a different plant!'... If anyone who knows the correct answer, please let me know the truth.
