Heliotropium arborescens 'Marine'
cherry pie
Heliotropium arborescens 'Marine' is a compact, bushy plant known for its richly scented clusters of deep violet-blue flowers, which appear from early summer to the first frosts. The fragrance, often compared to cherry pie or vanilla, makes it a favourite for sensory gardens, containers, and planting near seating areas.
Its dark green, slightly crinkled foliage contrasts well with the blooms, and the plant’s neat habit suits borders and pots alike. Ideal for sunny, sheltered spots, it’s a magnet for pollinators and adds reliable colour and scent throughout the season. Commonly grown as a half-hardy annual in the UK, it will overwinter in conservatories and frost-free glasshouses.

How to care for Heliotropium arborescens Marine:
Heliotrope prefers a sunny, sheltered spot with fertile, well-drained soil. Water regularly during dry spells, but avoid waterlogging. Deadhead spent flowers frequently to encourage more blooms and prevent the plant becoming leggy. Pinch out growing tips when plants are young to encourage bushier growth.
Feed every 2-3 weeks with a high potash fertiliser through the flowering season. Keep plants well ventilated to help prevent mildew and other fungal diseases.

Sowing instructions:
Sow indoors from late winter to early spring (February to April). Use trays or pots filled with a fine, free-draining seed compost, and press the seeds lightly onto the surface, covering lightly with compost. Maintain a consistent temperature of 20-24°C (68-75°F) and keep the compost just moist, not wet.
Germination can take 3-4 weeks or longer. Once seedlings are large enough to handle, pot them on individually and grow them in bright, cooler conditions. Harden off gradually before planting out after the risk of frost has passed.
