The Green Party has never been on the Indiana ballot for statewide office. However, it is trying to place a candidate for Secretary of State on the 2018 ballot. It has 500 signatures. The requirement is 26,700 signatures, due June 30. Although that is a severe requirement, it is lower than it has been since 1982, because the requirement is based on midterm year turnout, and the 2014 Indiana turnout was extraordinarily low.
No one has done a successful statewide petition in Indiana (neither independent nor third party) since 2000, when Pat Buchanan did it.
