Lemon (Eureka)

Description

Eureka Lemon is one of the most widely grown lemons in the world, valued for its consistent production and unmistakable, classic lemon flavor. This is the lemon most people picture—bright yellow, sharply acidic, and endlessly useful in the kitchen.

One of Eureka’s standout traits is its extended flowering habit. In warm conditions, trees often carry blossoms, immature fruit, and ripe lemons at the same time, providing a long harvest window rather than a single short season.

Overview

• Classic culinary lemon with bold, tart flavor.
• Highly productive with extended flowering and fruiting.
• Excellent for juice, zest, cooking, and preserving.
• More traditional and acidic than Meyer lemon.
• Self-fertile.
