Cycads: Ancient Plants for the Modern Collector

There are few plants that look quite as prehistoric as a cycad.

With stiff, feather-like leaves emerging from a thick central stem, cycads are often mistaken for palms or ferns. But despite their tropical appearance, cycads belong to an entirely different group of plants. They are gymnosperms, meaning they produce seeds without flowers or fruits, and their lineage stretches back hundreds of millions of years.

Today, cycads are still grown and collected around the world for their unusual shapes, slow growth, impressive cones, and ability to develop incredible character with age.

One species that I find particularly interesting is Zamia integrifolia, commonly known as the Florida coontie.

What Is a Cycad?

Cycads are an ancient group of seed-producing plants that have existed for hundreds of millions of years. They reached their greatest diversity during the Mesozoic Era, when dinosaurs were still dominating the landscape.

Although they can look remarkably similar to palms, cycads aren't closely related to them. Palms are flowering plants, while cycads are gymnosperms.

One of the easiest ways to tell them apart is to look at how they reproduce. Instead of producing flowers and fruit, cycads produce cones.

Many cycads are also dioecious, meaning individual plants are either male or female. Male plants produce pollen cones, while female plants produce seed cones.

This combination of an ancient lineage, unusual reproductive structures, and architectural growth makes cycads particularly interesting plants for collectors.

Zamia integrifolia: The Florida Coontie

Zamia integrifolia is one of the more unusual cycads because it doesn't have the towering appearance that people often associate with the group.

Instead, the Florida coontie is a relatively compact, low-growing cycad. Its stiff green leaves emerge from a thick underground stem, creating a dense cluster of foliage.

It is also particularly special because it is the only cycad native to the United States.

The species has been known by several botanical names over the years, including Zamia floridana and Zamia pumila, so collectors may encounter different names depending on the source.

The coontie's compact nature also makes it an interesting candidate for container growing.

The Caudex Is Part of the Attraction

One of my favorite things about cycads is the structure hiding underneath the foliage.

Many cycads develop a thick storage stem called a caudex. In Zamia integrifolia, much of that caudex remains underground, especially when the plant is young.

Over time, however, the relationship between the caudex, roots, and foliage can become an important part of the plant's character.

This is where cycads start becoming particularly interesting to bonsai and specimen-plant collectors.

Rather than simply treating the plant as something to grow in a container, you can begin thinking about the entire plant as a composition.

The shape of the caudex.

The direction of the roots.

The spread of the leaves.

The negative space around the plant.

And, of course, the pot.

A shallow bonsai-style pot can emphasize the horizontal character of a cycad, while a deeper container can provide a stronger visual foundation for a large caudex.

Growing Cycads in Containers

Cycads are generally slow-growing plants, which makes them well suited to container culture.

That doesn't mean they should be treated exactly like cactus or succulents, however. Their care requirements vary considerably between species.

For Zamia integrifolia, drainage is particularly important. The plant naturally occurs in well-drained environments, so a heavy soil that stays wet for long periods isn't ideal.

A coarse, well-draining growing medium is a good starting point for container culture. The goal is to provide enough moisture for healthy growth without allowing the roots to remain saturated.

Like many plants with substantial underground storage structures, cycads can also tolerate periods of dryness once established.

Light

Coonties are adaptable and can grow in both sun and partial shade. The amount of light can influence the appearance of the foliage and the overall growth habit.

When moving a plant from a shaded environment into stronger sunlight, acclimate it gradually rather than immediately placing it into intense sun.

Water

Allow the growing medium to dry somewhat between waterings rather than keeping it constantly wet.

The exact watering schedule will depend on the pot, soil, temperature, humidity, and amount of sunlight the plant receives.

As with cactus and succulent care, watering by a calendar isn't nearly as useful as learning to read the plant and its growing medium.

Cycads and Bonsai Pots

Although cycads aren't traditional bonsai in the same sense as Japanese maple, pine, or juniper, they can be incredibly effective when grown as specimen plants in bonsai-style containers.

This is especially true with Zamia integrifolia.

The plant's naturally compact growth and strong architectural form work extremely well with shallow pottery.

A good pot shouldn't overpower the plant. Instead, it should help emphasize what already makes the plant interesting.

A rugged cycad with a heavily textured caudex might look fantastic in a simple, earthy container.

A plant with particularly interesting roots might benefit from being planted higher, allowing some of that structure to remain visible.

And a mature specimen with a broad, symmetrical crown may look best in a low, wide pot that reinforces its horizontal shape.

There isn't necessarily one "correct" pot for a cycad.

That's part of the fun.

Raising the Caudex

One technique that can create a particularly dramatic specimen is gradually raising the plant to expose more of its caudex and roots.

This should be done slowly and thoughtfully rather than burying or removing large amounts of soil all at once.

As the plant is repotted over time, the grower can experiment with its planting depth and discover which portions of the caudex and roots contribute the most character.

This can completely change the appearance of the plant.

A cycad that initially looks like a simple leafy plant can eventually become something much more sculptural, with the caudex and roots becoming as important visually as the foliage.

This is one of the reasons I think cycads pair so well with handmade bonsai pottery.

The plant itself becomes a piece of living sculpture, while the pot becomes part of the composition.

The Coontie and the Atala Butterfly

Cycads also have some fascinating ecological relationships.

The Florida coontie is the primary host plant for the Atala butterfly. The butterfly's caterpillars feed on the foliage of the cycad before eventually developing into adults.

The relationship between the Atala and the coontie is a great example of why native plants can be so valuable in a landscape.

At one point, the Atala butterfly became extremely uncommon in Florida as its host plant became less abundant. The increased planting and conservation of coonties has helped provide habitat for the species.

So growing a coontie isn't simply about having an unusual prehistoric-looking plant in your collection.

It can also provide habitat for native wildlife.

A Word About Toxicity

There is an important consideration when growing cycads.

Cycads are toxic if ingested.

This includes Zamia integrifolia. Historically, the coontie was processed as a food source, but the raw plant contains toxic compounds and requires specialized processing to make it safe.

For modern gardeners and collectors, the important takeaway is simple: do not eat any part of a cycad.

It's also worth considering placement if you have pets or young children that may chew on plants.

Why Grow a Cycad?

For me, the appeal of cycads is their combination of history, structure, and patience.

They don't need to flower constantly to be interesting.

They don't need to grow quickly.

They don't need to be perfectly shaped.

A cycad can become more interesting simply by getting older.

The caudex thickens. The roots develop. The foliage changes. The plant gains scars and imperfections. Eventually, what started as a relatively simple plant can become an incredibly characterful specimen.

And that is exactly the kind of plant I love putting into handmade pottery.

Growing Plants With Character

Cycads are a reminder that some plants are worth growing for the long haul.

Zamia integrifolia may be relatively small compared with some of the world's giant cycads, but it has everything that makes this group so fascinating: an ancient lineage, unusual reproduction, a fascinating caudex, beautiful foliage, and a relationship with native wildlife.

Given the right conditions, a coontie can become an excellent container specimen—and with the right bonsai pot, its natural architecture can really stand out.

For collectors of unusual plants, cycads offer something a little different.

They're not trying to look like anything else.

They've been doing their own thing for millions of years.

And sometimes the best thing we can do as growers is give them a good pot and let that character develop.

Looking for a Pot for Your Cycad?

A cycad's container can be just as important as the plant itself. Shallow bonsai pots are particularly interesting for specimens with strong caudexes, exposed roots, and naturally architectural forms.
