Heliotropes, also known as cherry pie plants, are beautiful flowering plants that can be grown as perennials in some regions. However, in colder areas, they are often grown as annuals or brought indoors during the winter months.
In regions with mild winters and frost-free climates, heliotropes can come back year after year. They are considered perennial plants in these areas and can be left in the ground throughout the year. This allows them to establish a strong root system and continue to bloom and grow each season.
However, in colder regions where temperatures drop below freezing, heliotropes are not winter hardy and cannot survive the harsh conditions. In these areas, it is best to treat heliotropes as annuals or tender perennials. This means they will not survive the winter outdoors and will need to be replanted or brought indoors for the colder months.
If you choose to grow heliotropes as annuals, you can enjoy their vibrant blooms for one season and then replant new ones the following year. They can be a stunning addition to your garden or containers, providing a burst of color and fragrance throughout the summer months.
For those who prefer to keep their heliotropes as perennials, it is possible to overwinter them indoors. Before the first frost, carefully dig up the plants, taking care not to damage the roots. Place them in pots with well-draining soil and bring them indoors to a sunny, south-facing window.
Heliotropes thrive in bright sunlight, so providing them with as much light as possible during the winter months is crucial for their survival. Additionally, they prefer moist air, so consider placing a tray of water near the plants or using a humidifier to increase humidity levels.
During the winter, it is important to monitor the moisture levels of the soil and water the plants when the top inch of soil feels dry. Be careful not to overwater, as this can lead to root rot. With proper care and attention, heliotropes can continue to grow and bloom indoors during the winter, ready to be replanted outdoors once the danger of frost has passed.
While heliotropes can be grown as perennials in mild climates, they are often treated as annuals or brought indoors in colder regions. By understanding their winter hardiness and providing the necessary care, you can enjoy the beauty and fragrance of heliotropes year after year, regardless of your climate.
