YES, there are a couple of published papers documenting compared
lawsone content in different parts of the plant. Petioles have the
higest hennotannic acid content, therefore budding leaves with those
petioles are the thing to pick as that's where the lawsone content is
proportionally high and available. Cuttings in an aqueous solution
enriched in iron for hydroponic growth had the higest lawsone content
in their petioles. I one brief heat spell last summer, with a flush
of rain, those little ribs were bright orange red, later turning green.

In Armenia, scientists have experimented with growing henna and herbs
hydroponically that yield dyes and oils that have high comercial
value. The paper said they were getting 3 - 5 times the dye and oils
greenhousing compared to field grown.

Henna likes to be HOT. It won't bear anything under 11c and seems to
thrive at 40c daily highs.

(what's a petiole? It's that white part of Bok Choy, the red part of
Ruby Chard) (It's the rib in the tiny leaves)
