I just joined this forum, but here's my two cents. I've grown lemon drop, aji limon, and aji pineapple this year, and I can definitely say they are all the exact same tasty pepper. I used the same soil for all 3 of them in pots, and grew an aji limon, and an aji pineapple in the ground in the same soil. All 3 of them put off pods with the exact same shape, flavor, and heat levels. I sourced each different type of seed from different vendors as well. No matter what the name the vendor uses they are all indentical, delicious, and extremely prolific Baccatum pods.
These 3 names for the same Baccatum pepper should hopefully not be confused with the Aji Mochero, which is a Capsicum Chinense, but also ripens to yellow.
