The Habanero Pepper is a member of the 'Chinense' family of Hot Chilis. Typically the plants grow larger than most other hot Chiles such as the Cayenne or Jalapeno pepper.
Tip: Toss a pack or two of matches into the hole fanned out. Your Chili plants will love the sulfur. Sulfur is also a great Fungicide and kills harmful bacteria. This creates a Root Zone that is Habanero plant friendly. It enables the roots to spread out and grow quickly getting nourishment as well.
Also, spray with 2 tbs. of Sulfur mixed with water every two weeks thereafter...this will help keep avoid pepper plant diseases and help keep overall pepper plant problems away. Water the plant extremely well right after transplanting. It helps prevent transplant shock.
