Ancestral Plants For Modern Times

The Catholic church sex scandal, the tragedy in the Middle East, the lousy economy, the Scooby Doo movie we could all use a break from these powerfully trying times. How about stepping back 400 million years?

A short wander through the Strybing Arboretum's Primitive Plant Garden is a quick and legal way to escape from life in 2002. Standing on the raised wooden path that hovers over the garden, surrounded by the unusual foliage, you can almost believe you've entered an ancient world particularly with our dense summer fog swirling around you. (To complete the illusion, just ignore the constant roar of buses lumbering by.)

There are ferns of every size, from 1 foot high sword ferns to tree ferns that grow 7 feet and more. There are ground covers descended from ancient mosses, and horsetails worthy of Dr. Seuss deep green, 3 foot high reeds with bicycle spoke like leaves radiating out from the nodes. There are gingko trees, with their distinctive golden fan shaped leaves, and Southern Hemisphere conifers with thick, sharply pointed protective leaves.

These are the living descendants and distant relatives of ancient plants fossil evidence indicates that some of these plants can trace their lineage back 400 million years. Some plants, like the ground hugging liverwort, have changed little in that mind boggling length of time. The dawn redwood (Metasequoia) so closely resembles its ancient fossilized relatives that it is often called a "living fossil," while others, like the horsetails and club mosses, are much, much smaller than their towering ancestors were.

The plants in this garden cartier gold band ring knock off illustrate the path of plant evolution throughout history. This includes the extremely ancient aquatic organisms, like green algae, that are thought to precede land plants by hundreds of millions of years. Some of the next plants to develop were mosses and liverworts, which began inching their way toward land and now live at the water's edge. They have no true roots or leaves, but survive instead by sending out fine hairs to absorb water and the minerals it contains.

Several million years later, ferns some of the first plants to develop root systems as we know them today appeared. These were also among the first plants to develop the vascular system integral to most plants.

Millions of years later change occurs very slowly in the plant world cone bearing conifers such as the monkey puzzle tree made their appearance. These plants are believed to be some of the first to produce seeds, neatly tucked away in the cones (unlike the ferns, which reproduce from spores).

Fossils indicate that the gymnosperms, as the cone bearing plants are called, preceded plants with seed bearing flowers that make up the majority of plant life today. And, although the age of the first flowering plants is still disputed, the garden has descendants of some of the first flowering plants, in the form of anemones and hellebores.

These plants are survivors, adapting in various ways to changing climates and environments. According to the Strybing's director, , plants like the dawn redwood, fossils of which have been found in Europe and Greenland, were able to survive by finding a haven in the sparsely populated mountains of China's Szechuan province. In fact, these plants were long thought extinct until a botanical research party from San Francisco found them in Szechuan in the 1940s.

Botanists say it's unclear why these trees died out in other areas of the world two theories are natural extinction and human encroachment of their habitat but it's believed that their remote mountain location in China, far from the impact of progress, kept them alive.

Others, like the mosses, adapted by getting smaller, thereby needing fewer resources to survive. One thing you will notice is that these plants have adapted splendidly to San Francisco they're thriving here in our cool climate.

Most of these plants are descended from swamp dwellers, and they and many of their ancestors could not reproduce without an abundant water supply. To this day, many of them, like the New Zealand tree ferns, do not do well when the surrounding soil dries out.

And that is a big bummer in a place that receives rainfall only a few months out of every year. In fact, Medbury says, the reason the Strybing's primitive plant garden is so successful is because he and his staff "throw the water around." It's what he calls "the Sussex in the Sahara syndrome." Only, in this case, it's not the environs of merrie olde England and its cottage gardens we're trying to reproduce, but Jurassic Park. That kind of water use is understandable in a cartier wedding knock off rings for men public learning environment like a municipal arboretum, but Medbury adds quickly, "Imagine if everyone used this much water."

While it's ecologically extravagant to try to re create primitive gardens at home, having one or two of these plants in a pot is a great idea: Most of them do extremely well in a container, because their roots enjoy the snug confines of a pot. And a daily soaking of a 12 inch potted fern is much more water wise than turning your entire backyard into a swamp.

Note that these are primarily outdoor plants. There simply is not enough humidity in a house for the majority of them to survive, and no amount of misting will do the trick though you can do what my friend does. He rotate the plants from his roof garden into his apartment every week or so. By following this strategy, you'll get interesting houseplants that'll actually survive.

As for the soil, the plants recommended below like it wet but not soggy. You can start with a base of any good potting soil and add fir bark and vermiculite. The fir bark will allow the water to pass through the soil, as well as adding vital organic material, while the vermiculite acts like little sponges, holding on to some water. You might try a mixture of three parts potting soil, one part fir bark and one part vermiculite.

If you get the ancestral plant itch, consider one of these species. All of them have legions of fans, and there is no shortage of information online on how to cultivate them. Just remember, though, that they will need to be watered frequently, if not daily.

Spreading club moss (Selaginella)

Selaginellas, which like shade, make beautiful potted plants and will thrive in a terrarium. The creeping stems form dense mats of green foliage up to 12 inches across and a couple of inches high.

Most ferns do very well in pots, and, with more than 10,000 species available today, you're sure to find one you'll like. Ask at the nursery before you buy, but many of these grow to 24 inches or so.

Gunnera (Gunnera chilensis, or G. manicata)

This looks like dinosaur replica cartier gold diamond ring food. Big and bold, its leaves can grow to 7 feet across, though the chilensis leaves are smaller than the manicata's by a couple of feet. This is my favorite of these plants. Give it lots of water and lots of organic matter in the soil, and it will do you proud. This behemoth, which needs shade but can take sun in cooler areas, can get big even in a container, so be prepared for it to fill your fire escape. Check out the specimens at the arboretum.

Tasmanian tree fern (Dicksonia antarctica)

This hardy plant is easy to establish and grows as slow as molasses. I had one in a container for years, and it grew only a few inches each year although perhaps this is more imitation cartier gold band ring a testimony of my gardening technique than anything to do with the fern. It can grow to 15 feet, so if you haven't got the space, be prepared to hand it off to a friend when it outgrows your fire escape. It can take sun in cooler areas. Keep its soil moist, and add plenty of organic matter when potting.

Sago palm (Cycas revoluta)

This plant, another slow growing evergreen, can grow to 10 feet and closely resembles a palm. Many species of these plants, known as cycads, are threatened with extinction. They're very easy to grow; just give them regular water and part shade.

Local nurseries like Floorcraft or Sloat often carry these types of plants. If not, ask them whether they'll special order for you.
