Habanero is incredibly squat and bushy. Have you ever seen internode spacing this tight?

First time growing them, and all 8 are like this. They're in the exact same conditions as my cayennes right next to them. The cayenne are a little tighter than usual, but basically normal, whereas these just seem extreme. Google images of Habaneros im seeing are all look like your standard .5 – 1" spacing. Maybe its the variety (Helios), I dont know, its very impressive though.
