The Pines of Rome

December is not really the time to go wildflower hunting in Italy, but I happened to be there for other reasons last week, and kept one eye on the lookout for things botanical.  Of course, Italy isn’t exactly buried in snow in December.  Except for the high mountains, the country enjoys a mild Mediterranean climate – there are palm trees all over the place!  So it’s like California or Florida; there’s always some kind of plant life.

here in Florence,  are Pinus pinea.
Rome is sometimes referred to as the eternal city, and some of its most remarkably plants are eternal in the sense of being evergreen.  I have heard Respighi’s “Pines of Rome” many times, without really knowing what the big deal was, but upon actually seeing pines in Rome, I must say they are truly marvelous.  The common species is the umbrella pine, Pinus pinea, whose trunk branches into a unique rounded crown.   It is native throughout the Mediterranean region, and has been cultivated for 6000 years for its edible seeds.  Its presence turns any landscape into a classic work of art, especially when juxtaposed against small groves of Italian cypress.

Italian cypress, or Cupressus sempervirens, also has a unique shape: compact, upright, narrow, reaching for the sky.  It is often planted in cemeteries, not only for its heaven-aspiring posture, but also because the roots grow straight down and do not disturb graves.  It too is native throughout the Mediterranean region and Middle East, but seems to be especially characteristic of the Italian landscape.

The most common palm is the windmill palm, Trachycarpus fortunei, a native of China and one of the most cold-hardy palms (see “The many uses of Trachycarpus” in my publication list).   Along the coast are majestic specimens of the Canary Island Date Palm, Phoenix canariensis, which is a staple of the Riviera landscape.  A palm native to parts of the Mediterannean coastal scrub is the European Fan Palm, Chamaerops humilis, of which I think I got a glimpse from the bus as we headed for Pisa.  I’m sure that if we’d gone further south, we would have seen many more cultivated palms.

Olives ripen throughout the Fall in Italy.
December is the time for fruit.  There are ripening olives (Olea europea), as well as the bright red fruits of holly, Pyracanthus, and Nandina, not to mention the edible fruits of the tree strawberry, Arbutus unedo.  The bright red color of many of these fruits attracts hungry birds, who in exchange for the meal carry the seeds in their guts until they relieve themselves in a new location.
Holly berries ripen just in time for Christmas.

If I have the privilege of traveling again in this beautiful country, I will go after the winter rains, in March or April, which is truly the wildflower season.

For the Love of Poppies

This is an excursion to the grassy slopes and open spaces of southern California, transformed into a technicolor extravaganza after the winter rains.  Here, California poppies dominate, but share space with numerous other species. Click on the following link:

The western red columbine and the beginning of my downfall

On the several occasions when we moved into a new house, the first order of business for my father was to begin planting fruit trees.  That was followed by roses and other ornamentals.  So there was an awareness of plants in my earliest memories.  The bug didn't hit my though, until summer camp in the sixth grade, somewhere up in the San Bernardino Mountains.  We had to do a project, and all the seeds planted in my subconscious suddenly coalesced, and I chose wildflowers. 

Aquilegia formosa
Before that I had decided to become a nuclear physicist, I think after being inspired by one of Frank Baxter's Science episodes on TV - "Our Mr. Sun," or something like that.  Anyway that was discarded on that fateful day at camp, and from then on I was committed to being a botanist.  Through all the science training and career as a biology and botany professor, I was deep at heart a wildflower enthuisast, and to this day, I am always looking for that next flower to capture on film (or now as a series of bits in a digital file - not nearly as romantic!).

The primary evangelist for my conversion was a population of the western red columbine, Aquilegia formosa,  occuring along a stream near camp.  The dainty flowers, aptly named for the female clown in a popular 18th century English theater, dangle an dance in the breeze, waiting for hummingbirds to feed on their nectar and bring pollen.  This species occurs throughout the Pacific states in mountain meadows, one of many that can be found throughout North America and Eurasia.

Stay tuned.  This is just the beginning!
