Aji Colorado is a baccatum pepper. It ripens nice and early and will give you lots of peppers. It is commonly found in Peru and Bolivia but has been popping up in more North American seed catalogs because it grows really well here too.
They are a very sweet and fruity pepper. Depending on growing conditions they can vary from mild to jalapeño heat level. They grow well in hanging baskets but you'll get smaller pods.
The plants can grow to 4 feet.
