Where it comes from

PIE word

*sóh₂wl̥

The noun is borrowed from French héliotrope, from Latin hēliotropium (“plant which turns to face the sun; bloodstone”), from Ancient Greek ἡλῐοτρόπῐον (hēlĭotrópĭon, “European heliotrope (Heliotropium europaeum); bloodstone; solar clock, sundial”), from ἥλῐος (hḗlĭos, “the sun”) (ultimately from Proto-Indo-European *sóh₂wl̥ (“the sun”)) + τρόπος (trópos, “a turn”) (from τρέπω (trépō, “to rotate; to turn”) (from Proto-Indo-European *trep- (“to turn”)) + -ος (-os, suffix forming nouns from verbs)) + -ῐον (-ĭon, diminutive suffix forming nouns). By surface analysis, helio- + -trope.

The French-derived spelling displaced Middle English elitrope, eliotropius, elitropium (“plant which turns to face the sun; bloodstone”) [and other forms], from Old English eliotropus, from Latin hēliotropium (see above); and Old English siġelhweorfa, sōlsece, and sunnfolgend (“heliotrope flower”).

Noun sense 6 (“synonym of bloodstone”) is from the fact that a piece of the mineral placed in water is said to change the sun’s rays to a blood-red colour: see the 1601 quotation.

The adjective is probably derived from the noun.
