Lemon (Genoa)

Description

Genoa Lemon is a dependable, classic lemon that shines in home gardens where space, productivity, and resilience matter. Long grown in Mediterranean-style climates, it delivers the bright acidity and versatility people expect from a true lemon, with a more compact, manageable growth habit.

One of Genoa’s standout traits is its dense foliage and steady production. In warm, well-managed conditions, trees can flower and fruit over an extended season, sometimes carrying blossoms and lemons at the same time. The fruit is thin-skinned, typically low-seed, and excellent for juice, zest, cooking, and preserving.

Overview

• Classic culinary lemon with bold, tart flavor.
• More compact and densely foliated than many lemon varieties.
• Typically seedless with thin, aromatic peel.
• Productive with extended flowering in favorable conditions.
• Self-fertile.
