Curcuma alismatifolia, Siam tulip or summer tulip (Thai: ปทุมมา, RTGS: pathumma; กระเจียวบัว, RTGS: krachiao bua; ขมิ้นโคก, RTGS: khamin khok) is a tropical plant native to Laos, northern Thailand, and Cambodia. Despite its name, it is not related to the tulip, but is a close relative of turmeric. It can grow as an indoor plant. It is a perennial herb growing up to 2 feet (0.61 metres) tall.
Malvidin 3-rutinoside is a pigment responsible for bract color in C. alismatifolia.
