Key Lime Tree (FL) Information
About The Key Lime Tree (FL)
This is the true lime — Citrus aurantifolia, also known as the Mexican lime, West Indian lime, or bartender's lime — and it tastes nothing like the big, blunt Persian limes stacked at the grocery store. The fruit is small, round, and golf-ball-sized, with a thin, smooth rind that ripens from green to a pale yellow-gold. What sets it apart is the flavor: a sharp, high, almost floral tartness wrapped in an unmistakable aromatic perfume. One squeeze and you understand why authentic key lime pie, classic margaritas, mojitos, and ceviche all insist on this lime and accept no substitute.
Why You'll Love It:
- Flavor you can't buy fresh. True Key limes are rarely sold whole and bruise quickly in shipping, so growing your own is often the only way to taste them at their fragrant peak.
- Heavy, year-round fruiting. In warmth this tree flowers and fruits almost continuously, so a single plant can keep a steady supply of limes coming rather than one short season.
- Small fruit, intense return. Each lime is tiny but loaded with juice and aroma — a few are enough to flavor a whole pitcher, a marinade, or a dessert.
- A natural for pots and patios. Compact and forgiving of root confinement, it thrives in a container that can summer outdoors and shelter inside when the cold arrives.
- Fragrant white blossoms. Small, sweet-scented flowers appear in flushes through the year, perfuming a patio or sunroom long before the fruit ripens.
