Creating one free and two paid levels, all with unique labels

I want to have three levels:

Sprout – a free, base level

Grow – a moderately priced paid level

Thrive – a higher priced paid level

Is there a way to hide the automatic free level and have Sprout be a $0 paid level? Or is there a way to rename the free level Sprout? What do I need to do to make that happen, and how do I do it? Thank you in advance for your help!
