Summary
Amethyst Basil combines the familiar flavor of sweet basil with dramatic deep purple foliage for a striking edible accent in gardens and containers.
Its large, aromatic leaves deliver the classic basil taste used fresh in salads, sauces, and garnishes. The rich coloration provides bold contrast alongside green herbs and vegetables, making it equally suited to ornamental plantings.

Care
Amethyst Basil Care
Provide at least 6–8 hours of direct sunlight daily for best leaf development and strong coloration.
Plant in well-drained soil enriched with organic matter. Keep soil evenly moist but never saturated during active growth.
A light application of slow release fertilizer at planting supports steady growth.
Pinch flower buds if continued leaf production is desired. Protect plants from frost and prolonged exposure to temperatures below 50°F.
Container Growing: Use a container with drainage holes and quality potting mix. Container-grown plants may require more frequent watering than in-ground plantings. Plants hardy in the ground may require winter protection when grown in containers in colder zones.
