Nine years ago, during a semester abroad, I found myself alone in the open courtyard of the Palazzo Medici Riccardi in Florence, Italy, surrounded by an ornamental grove of potted citrus trees.

I'd been wandering around the place all morning trying to find the elusive garden, and by the time I got there I was grateful to find it void of tourists and clicking cameras.  

It's hard to imagine that a simple plant held so much history in its leaves, but these trees, heavy with fruit, certainly did. 

To the Medici, oranges represented wealth and fertility. If you look closely at Medici commissioned paintings, like Botticelli's La Primavera, look for the citrus trees.  They are present in many of the art forms that the family had a hand in.

The single specimen garden was one of the most beautiful sights I'd ever seen. 

And one day I want my own grove. 

Not only do the citrus trees retain their shiny, evergreen leaves all year, but citrus blossoms produce the most intoxicating scent. A few months ago I got my collection started with two Meyer lemon trees that were covered in blossoms and put them just outside the front door. The fragrance wafted into the house every morning when I left for work and every time I crossed the threshold in the evenings. Heavenly! 

I've also been looking to the ornamental citrus gardens in Charleston for ideas. I've spotted several examples, some potted, some espaliered (which just means that they are trained to grow completely flat against a wall or other structure).

I love how espalier looks, so I thought I'd post a few images of other fruit trees trained in a similar fashion. Turns out that the practice goes back even farther than the Medici, all the way to ancient Egypt. For centuries, people have used it to take advantage of space in small gardens, to create hedges in open areas, and more. 

If you're thinking of adding citrus or fruit trees to your garden, one of the best mail-order sources is the Tasteful Garden in Alabama. And if you'd like to take the whole idea one step further with professionally trained espalier specimens, River Road Farms is your best bet. 

All you'll need after that is a pitcher of sweet tea to put those fresh lemons in...
