Marine Blue Heliotrope

Marine Blue is a compact garden heliotrope selection sold under that name, with a reported mature size of about 10–14 inches tall and 12–18 inches wide. It belongs to Heliotropium arborescens, a tender perennial commonly grown as a warm-season annual in colder regions. [Goldeman’s nursery listing](https://goldemansgreenhouse.com/plant-heliotrope) · [North Carolina Extension plant profile](https://plants.ces.ncsu.edu/plants/heliotropium-arborescens/) ## Garden Use Plant Marine Blue near a patio or path, or use it as a compact flowering accent in a seasonal container or the front of a border. The nursery lists Marine Blue among its heliotrope varieties and describes heliotrope as suitable for pots and attractive to bees and butterflies. ## Growing Conditions Provide full sun for the strongest flowering, with light afternoon shade useful in hot summer climates. Grow it in humus-rich soil that stays evenly moist while draining well; avoid allowing roots to sit in water. North Carolina Extension notes that garden heliotrope blooms through summer and can be pinched to encourage a bushier form. ## Maintenance Check container moisture regularly during warm weather and water before the root ball dries out. Pinch or lightly trim the tips if the plant becomes open, and remove faded flower clusters for a tidier display. Protect it from frost; in most temperate gardens it is used as an annual rather than expected to overwinter outdoors.
