About Heliotrope

Heliotrope (Heliotropium arborescens) is a Peruvian annual or tender shrub cherished for its dense clusters of small, richly vanilla-scented flowers in deep violet-purple, lavender, and white.

Care essentials

Light

Plant in full sun for best flowering; in NE Florida's intense summer heat, afternoon shade helps prevent wilting and extends bloom. Minimum 6 hours of direct sun daily.

Water

Water consistently and do not allow the soil to dry out completely — heliotrope dislikes drought. In Florida's heat, check containers daily; in-ground plants need water 2–3 times per week until established, then weekly deep watering.

Soil & Fertilizer

Grow in fertile, organically rich, well-draining soil. Amend sandy Florida soils with compost before planting. Fertilize monthly with a balanced slow-release fertilizer during the growing season to support continuous bloom.
