Heliotrope Flower Meaning & Symbolism – The Essentials
In Greek mythology, the sun god Helios scorned the nymph Clytie. After she died of a broken heart, Helios transformed her into a heliotrope. Her flowers turn upward to follow the sun as he traverses the sky each day. That’s why heliotrope’s fragrant blossoms symbolize devotion in the language of flowers.
About Heliotrope Flowers
Heliotrope Flowers – Family, Genus, and Taxonomy
Heliotropium is a genus of flowering plants that belongs to the borage family (Boraginaceae), also known as the forget-me-not family. Heliotropum contains about 325 species. The cherry pie plant, or H. arborescens, is the most common species grown in the Americas and Europe.
Botanical Characteristics, Colors, Fragrances, and Toxicity
Heliotrope grows as an annual in cooler climates and a perennial or half-hardy perennial in warmer climates. In its natural habitat, it grows up to six feet tall and eight feet wide.
Its dark green foliage features prominent veins. Ovate leaves are arranged alternately and feel rough to the touch.
Blooms are trumpet-shaped, and set on a coiled stem. Heliotrope flowers have a wonderful fragrance that’s likened to vanilla, sugar, or even freshly baked cherry pie.
A Toxic Beauty:
Every part of the heliotrope plant is toxic to humans and can cause digestive problems or liver damage when ingested in large amounts. When ingested over a period of time, heliotrope has been known to cause severe liver damage to horses.
Popular Heliotrope Flower Types, Species, and Cultivars
There are more than 320 species in the Heliotropium family. The most common type grown as an ornamental is H. arborescens. Popular cultivars include:
- ‘Fragrant Blue’: this variety has strongly scented flowers that turn deep blue when temperatures drop
- ‘Marine’: a compact variety that grows to 14 inches tall and blooms with dark purple blossoms
Other species of heliotrope include:
- Blue heliotrope (H. amplexicaule): A drought-tolerant species indigenous to and cultivated in South America; this blue-flowering plant has naturalized in Australia, where it’s considered an agricultural weed
- European heliotrope (H. europaeum): Native to Europe, Asia and North Africa, this annual grows to about 15 inches tall, with white flowers and a strong, unpleasant scent
- Indian heliotrope (H. indicum): This Asian native reaches 19 inches in height and blooms with light purple and white flowers atop a dramatic green calyx
- Salt heliotrope (H. curassavicum): A salt-tolerant ground cover that spreads to four feet wide and produces white flowers year-round
“Heliotrope” comes from the Greek for sun, helios, and trepein, or “to turn.” The name refers to heliotrope flowers’ tendency to turn and face toward the sun throughout the day.
Another common name for the flowers, the Middle English “turnsole“, also means to turn toward the sun.
What Regions are Heliotrope Flowers Native To?
Flowering plants in the Heliotropium genus grow around the world, from the Americas to Asia, Africa to Europe. The common ornamental H. arborescens is native to subtropical regions of Peru.
When are Heliotrope Flowers in Season?

In USDA Zones 10 and 11, heliotropes can be grown as perennials. In other, cooler, zones, the plants are grown as annuals.
Uses and Benefits of Heliotrope Flowers
Heliotrope Flowers in Herbalism and Medicine
In 16th century Europe, the “Doctrine of Signatures” held that plants that looked or behaved in ways that resembled parts of the human body could have medicinal effects on that body part. At the time, the sun was thought to control the heart, breathing, and vertebrae.
Plants that “followed the sun,” such as heliotrope, were thought to affect bodily functions such as circulation and breathing and were used in medicinal treatments. Today, it’s known that heliotrope contains compounds that can harm the liver. Ingesting any part of the H. arborescens as medical treatment isn’t recommended.
However, heliotrope tinctures may be used topically to treat skin ailments, such as warts, calluses, wounds, and infections. Essential oils may be used for massage.
The species known as Indian heliotrope (H. indicum) is an ingredient in the traditional medicine of the Philippines. Juice from the foliage is used to treat ulcers, wounds, and conjunctivitis.
Toxicity, Bee Friendliness, and Pollination
All parts of H. arborescens are toxic and can cause liver damage over time. Humans, dogs, cats, horses, and livestock should not ingest heliotrope.
Bees, butterflies, and other pollinators are drawn to heliotrope, thanks to its fragrant, trumpet-shaped flowers. Heliotrope makes a good addition to a pollinator garden.

The Meaning, Symbolism, and Cultural Significance of Heliotrope Flowers
The symbolism behind heliotrope began with a Greek myth. The water nymph Clytie was in love with the sun god, Helios. Unfortunately for Clytie, he just wasn’t that into her and left her for another.
The heart-broken Clytie pined for Helios, sitting in one place and turning only her head to watch his chariot travel across the sky each day. Eventually, she wasted away, and Helios transformed her into a flower.
The heliotrope turns its “face” to follow the path of the sun, just as Clytie once did. To the Victorians, the heliotrope was thus a sign of devotion and eternal love.
