Siam Yellow

Siam Yellow is a Capsicum annuum chilli sold under that name in seed catalogues, but available information is inconsistent. Most listings describe it as a very mild or non-hot yellow chilli used for colour and flavour rather than heat. Because sellers repeatedly state it has little to no heat, a working value of 0 SHU is used here.

Plants are generally described as compact, commonly between 45.0 and 70.0 cm tall depending on source. Pods ripen from dark green to yellow or yellow-orange. Precise pod length and width are not consistently documented across sellers.

There is significant confusion about origin. Some seed listings claim Mexico or South America, while the name “Siam” suggests Thailand. Other similarly named peppers such as “Yellow Siam” are described elsewhere as hot Thai types, which may represent a different cultivar being sold under a similar name. This naming overlap suggests possible mislabelling or multiple distinct peppers sharing the same or similar commercial name.

No formal breeder record, botanical registration, or clear historical documentation was found for this specific name. Available information comes primarily from seed sellers rather than academic or agricultural records.
