Discover the different types of Heliotrope flowers and watch these sweet-smelling flowers with purple petals turn your garden into a cosmopolitan beauty to behold.
Also known as Heliotropium arborescens, heliotrope is a sweet smelling flower, prized for its cute purple petals. This flower species grows annually or perennially, depending upon time and place. If this is your first time getting to know about this flower variety, you must be wondering what the meaning behind its unique name is.
Basically, heliotropius is a Greek word, with “helios” meaning “sun”, and “tropos”, meaning “turn”. The name is derived from the plant’s characteristic of turning its leaves to face the sun. This is a habit common to all heliotropic plant species which they habitually exhibit. Also known as Garden heliotrope, this clustered blossom holds special meaning/symbolism as well. Heliotrope represents eternal love or is a symbol of someone that is deeply devoted.
Identified as a shrubby perennial, this lovely plant belongs to the borage family of herbs, shrubs, and trees which characteristically are blue and fuzzy-leafed. While many think that it ranges in shades of purple, there are a few varieties of heliotrope flowers in a white color. Each of them features five-lobed petals which are clustered together, resembling ever-so-pretty Scorpion grasses!
Did you know that this cosmopolitan genus has around 325 species? Sounds remarkable, right? It is, indeed, worth learning about its popular kinds and this article discusses them in detail. Read on.

Scientifically known as heliotropium arborescens, marine heliotrope is a deeply violet-colored flower with large vibrant clusters. The notable clusters spread up to 12 to 18 inches tall and wide. This delightfully fragrant heliotrope variety blooms in spring, summer, and autumn, delightfully adding vibrancy to your garden or yard. Since it is a tropical plant, it cherishes the summer heat, making it a heat-tolerant plant. However, this floral variety opposes extremely cold temperatures so growing them in winters is a big no-no.
The University of Minnesota lists heliotrope marine a deer-resistant and shade-resistant plant. This upright plant does not require frequent watering and only needs to be fertilized every two weeks. The exquisite scent is an added advantage as it elevates the beauty of hanging baskets, flower containers, patio borders, etc.
Before you plant this type of heliotrope, make sure that your heliotrope marine hardens off in a cool, windy night. For that, you will need to leave it outside in a covered area for a couple of days or else it will wilt away. Pick a sunny area and plant its seeds deep enough to cover the top of the root ball. Water it enough and fertilize once or twice a season.
Belonging to the Boraginaceae family, heliotropium “dwarf marine” is found in dry, sandy areas like in Mexico and South America. They have a sweet scent to them which is why they are commonly cultivated in a garden and yard. This variety of heliotropes is identified by its miniature so it will look good even if it is planted as a separate plant. Owing to its small-size, this variety of heliotrope can be cultivated in containers as well as the front of decorative borders. The gorgeous blooms are attractive to bees, moths, and butterflies.
Dwarf marines can reach up to the height of 35 cm, richly filled with thyroid inflorescences with bright blue floral. Heliotropium dwarf marine is best grown in moist, well-drained soil in full sun or partial shade. Make sure to remove spent blooms to increase flowering. The plant also needs regular watering to ensure healthy plant growth.

In several Pacific islands, velvetleaf soldierbush is used for treating ciguatera fish poisoning which is caused by ciguatoxins – a type of life-threatening toxin found in fish. Researchers from the Louis Malarde Institute in French Polynesia and Pasteur Institute in New Caledonia have concluded that the plant consists of therapeutic leaves, as they contain rosmarinic acid – known for its antioxidant and anti-inflammatory properties. The scientists and researchers believe that rosmarinic acid can help eliminate signs and symptoms of ciguatoxins. Scientists at the Institute of Research for Development (IRD) also back this statement.
Some of the most popular names of this common heliotrope variety are velvetleaf soldierbush, octopus bush, and veloutier.

Like all heliotrope varieties, Heliotropium anomalum are cultivated from seeds. The seeds of heliotrapium anomalum are super small. They need to be dried on an absorbent paper and kept in the sun before they are planted in the ground. Once the seeds have dried down, sprinkle them on the top of the moist, well-drained pot. Place the pot in shade and keep it moist. Note that germination takes up to 2 to 3 months. Polynesian heliotrope is not only propagated through seeds but from cuttings as well. However, these cuttings need to be done without the use of rooting hormones.
