Image taken from Figure 1 of paper by Sumi et al. https://doi.org/10.1093/pcp/pcaf057 showing a schematic diagram of the betalain biosynthetic pathway, images showing flower color variation, different stages of flower development for analysis, and a graph showing betalain accumulation (betaxanthin and betacyanin) in P. umbraticola varieties.

Flower power…🌼

Sumi et al. have elucidated the basic #betalain biosynthesis pathway, and show how #flower colour variation in the Caryophyllales is due to the ratio of betacyanin & betaxanthin pigments produced

Hyacinth flowers simmering

The resulting decoction, deep blue

The very blue lake which is the hyacinth pigment, blue sludge.

It's that time if the year 😁
