CYCAS HOUSE

Cycads are a group of plants that have existed on Earth for 250–300 million years. They are often referred to as “living fossil plants.” The reason they are called fossil plants is that fossil specimens dating back millions of years show almost no difference from the living plants found today. Together with Ginkgo biloba and certain conifers, cycads belong to the class of “Gymnosperms” (open-seeded plants), which reproduce by producing cones.

Once widespread throughout much of the world, cycads became restricted mainly to tropical regions as the Earth’s climate cooled, with only a few species remaining in temperate zones. Following the extinction of some species, approximately 310 cycad species exist today. Although cycads now survive in only a limited number of regions, they were widespread across the globe during the Jurassic Period. For this reason, the Jurassic is often referred to as the “Age of Cycads.”

Cycads are generally thick-trunked plants with striking foliage that forms an attractive crown. Individual plants are either male or female. Male plants produce long, slender cones that release pollen, while female cones are usually oval and produce seeds after pollination. In their natural habitats, certain insects carry pollen and facilitate fertilization. In Türkiye, almost all cycads known and commonly used as ornamental plants in recent years are Japanese Sago Palms (Cycas revoluta).

The Palm Center in Köyceğiz, Muğla, began propagating cycads from seed 30 years ago, in 1993, starting with the Japanese Sago Palm. Later, several other cycad species were also successfully propagated. Since there are no native insects in Türkiye capable of pollinating cycads, artificial pollination is used at our center to produce seeds. Our center was among the first producers in Europe to propagate the Taiwan Cycad (Cycas taitungensis). Today, seeds of this species produced at our center are exported internationally.

Cycas House : At the Palm Center Botanical Garden, a greenhouse became necessary for cycad species that could not be planted outdoors due to climatic conditions. In 2023, a 120 m² greenhouse was constructed within an area of approximately 400 m². The Cycas House, with both its indoor and outdoor areas landscaped with cycads, was officially opened on 29 December 2023.

During the initial phase, 147 cycads representing 12 species were planted throughout the complex. Most of the outdoor plantings consisted of Taiwan Cycads (Cycas taitungensis) and Dioon species from the American continent (Dioon edule var. angustifolia). Young Taiwan Cycads grown from seeds produced at our own nursery were planted particularly to support and expand our seed export program.

Within the Cycas House complex, the family Cycadaceae is represented by Cycas circinalis, Cycas media, Cycas taitungensis, and Cycas thouarsii. The Japanese Sago Palm (Cycas revoluta) was not planted in this complex, as extensive plantings of this species already exist both within our Botanical Garden and throughout the Palm Center.

The cycads belonging to the family Zamiaceae in the complex are Zamia floridana, Zamia furfuracea, Dioon edule var. angustifolium, Dioon spinulosum, and Encephalartos hildebrandtii.

I AM A CYCAD

I have existed on Earth for well over 200 million years. During this immense span of time, which you consider unimaginably long, I have changed less than you do during a single lifetime. I witnessed your ancestors arriving on Earth more than 200 million years after me.

I saw the rise and fall of the dinosaurs. The Jurassic Period—the age of the dinosaurs—was among the finest millions of years of my existence. The world was warm, and I grew rapidly and spread across the globe, from the poles to the equator. During the following Cretaceous Period, however, my former dominance began to fade. Flowering plants, known as angiosperms, appeared and gradually occupied the world by dispersing their seeds far and wide.

Do not compare me with other flowers and trees. In the plant kingdom, only I and my contemporary, the Ginkgo tree, possess motile sperm cells capable of movement, much like yours. I was already 170 million years old when the Alps, the Andes, and the Himalayas were merely small rises in the landscape. I watched them grow into the mighty mountains that stand today.

After all that I have experienced, I now rest in the warm regions of the world. Humans search for and discover my fossils across the globe, while at the same time expanding into my habitats and threatening my survival. Today, they claim to protect me through international agreements. Not so long ago, during times of war and famine, people in Japan survived by making flour from my seeds.

How ancient I truly am, and how resilient I have proven to be, lies beyond the full comprehension of those who call me a “Living Fossil.” I am tired, but I am content.

I am a Cycad.
