Both Gardenia Jasminoides (Gardenia) and Gardenia Florida (Gardenia) are flowering plants in the coffee family, Rubiaceae, native to the tropical and subtropical regions of Africa, Asia, Madagascar and Pacific Islands. This evergreen shrub is known for their beautiful white flowers with exotic scent.
It is less known that pigments can be extracted from the gardenia. Depending on the ripe grade and state of the plant, red, yellow or blue colors can be achieved that help us create tubbubble’s water effect without any artificial dyes.
You need a lot more gardenia in a formula to have the effect you get (as compared with food colors, for example), but it is worth it as gardenia has no allergenic potential.
