Heliotropes are beautiful, fragrant plants that are often used to brighten up gardens, patios, and indoor spaces. Known for their ability to “track” the sun (a behavior called heliotropism), these plants are not only attractive but also relatively easy to grow if you follow some key guidelines for planting and care. In this article, we’ll go over everything you need to know to grow healthy heliotropes, from choosing the right variety to maintaining their needs throughout the growing season.
1. Understanding Heliotropes
Heliotropes (Heliotropium arborescens) are native to South America, particularly in areas like Peru and Ecuador. The plant is famous for its clusters of small, often fragrant flowers that can come in a variety of colors, including purple, blue, white, and pink. Heliotropes are also known for their distinct heliotropism, where the flowers and leaves turn to follow the sun throughout the day.
The plants typically grow as shrubs or small bushes, reaching heights of about 1 to 3 feet tall and wide. They thrive in full sunlight and require warm temperatures, making them an ideal choice for summer gardens or containers.
2. Choosing the Right Location for Heliotropes
Heliotropes are sun-loving plants that require plenty of sunlight to thrive. When selecting a spot for planting, keep the following factors in mind:
- Sunlight: Heliotropes need at least 6 hours of direct sunlight each day to produce their vibrant blooms. Full sun will ensure the plant’s growth and encourage the flowers to follow the sun’s path.
- Soil: These plants prefer well-draining soil that is rich in organic matter. Heliotropes do not like soggy roots, so avoid heavy clay soils. A slightly acidic to neutral soil pH (between 6.0 and 7.0) works best.
- Spacing: If planting in the ground, space your heliotropes at least 12 to 18 inches apart to allow for good air circulation. This will also help prevent disease.
