In 1906, a London bookbinder named Joseph Dent began publishing "Everyman's Library." His purpose was to make fine literature available to "every man" in a reasonably priced edition. Everyman® is still in business today.

Yew bonsai at the ABS Symposium in St. Louis, 2004. |
About 100 years later (as it happened,) I began looking for an "everyman's (and every woman's) bonsai:" a species that I could recommend both to those who were just getting started in bonsai, and to experienced practitioners who wanted a new challenge. After several years of looking, I finally realized that the species I was after had been all around me, all along: the yew! (
Taxus.)
Besides being a mainstay of landscaping in much of the USA and Europe, the yew makes a very good subject for bonsai. That is so because yews are:
- Tolerant of hard pruning, of roots and top;
- Tolerant of a wide range of conditions;
- Able to bud back on older wood, with proper care;
- Cold-hardy to -30 ° F (-34° C) in the ground, somewhat less in a pot;
- More forgiving than many species (for the beginner;)
- Challenging and rewarding (for the experienced;)
- Great for carving and deadwood;
- Suitable for any size and almost any style;
- Readily available in much of the USA and Europe in general-purpose nurseries.
At the same time, there are a few cautions about yews. One in particular must be taken into account.
- Yews are poisonous to humans and most of our domesticated mammals. If you have a small child in the house, consider waiting until he or she is old enough to understand the danger.
- Yews are not for hot climates. They grow best in the world's temperate-to-cold zones.
- Yews don't tolerate soggy soil. Poor drainage will kill them.
- The branches should not be worked in winter: the cambium can separate from the sapwood and the whole branch can die.

Mankind has a long association with the yew. Yew wood is hard and durable, so until the development of
plastics it was widely used for items that took a lot of wear. It is also
strong and flexible, ideal for bows. The famous "Iceman," whose
mummy was found in 1991 after 5,000 years in an Italian glacier, was carrying an unfinished bow made of yew. More than 4500 years after his death, longbows, made of yew more often than any other wood, played a decisive part in the English victories at Crécy (1346) and Agincourt (1415.)
Julius Caesar recorded that the Gaulish chieftain Catuvolcus
poisoned himself with yew berries rather than live under Roman rule. In more recent times, tho, with the development of gunpowder and later of plastics, yews have come to be used for landscaping but not much else.
The yew is an evergreen conifer. Its "berry" (or
aril) is in fact a modified cone, closer in structure to a pine cone than a grape. Unlike the majority of seed-bearing plants, yews are dioecious, with individual plants being either male or female.

Yews are slow-growing and long-lived. The oldest yew that I have personally seen is the Glencormac yew (click
here.) At 2,000 years old, it is still far from the oldest yew known. That honor goes to either the Fortingall yew, in Scotland, or the Llangernyw yew in Wales. Determining the precise age of an older yew is often impossible because, while yew wood is quite rot-resistant, after several millenia even it starts to break down. Botanists are then only able to establish an age
range.

Taxonomists disagree on whether yews should be classed in a single, and highly variable, species, or in as many as 11. But only two of the commonly accepted species, and one hybrid, are widely used for landscaping in the USA, and for bonsai:
- English or European yew, Taxus baccata;
- Japanese yew, Taxus cuspidata;
- the "Anglojap" hybrid, Taxus x media, which happily combines the greater vigor of T. baccata with the greater cold resistance of T. cuspidata.
There are dozens of
T. x media cultivars, and most of the yews sold in general-purpose nurseries in the USA belong to one or another.
When selecting a hybrid yew for bonsai, check
its cultivar's characteristics.
'Hicksii,' for example, has a strongly upright growth habit, which you would be fighting constantly; I would pass it up. 'Densiformis' breaks new buds all over the place, and 'Dark Green Spreader' is just that; I like them both. Some cultivars are female; you might like the bright red arils in autumn.

Like junipers and arborvitae but in contrast to pines and spruces, yews sprout new branches at random rather than in whorls. A nice thing for the bonsaiist is that such "irregular-branching" conifers also are able to break new buds on wood as much as 30 years old.
Another difference between yews and pines is in the strength of their wood: yew wood is significantly stronger. Consequently, as a yew matures, its primary branches are not as likely to droop as those of a pine or spruce. The branch configuration of a yew, in fact, can often look more like a maple's or a fig's, than a pine's. This means that, while a yew can certainly be styled in the classic coniferous styles, the artist doesn't need to be limited to those.
A couple of decades ago, bonsai artists in the southern USA developed a new style variation, called "flat-topped," for their bald cypress. Basically a modified broom, it reflects quite accurately the natural look of a bald cypress in the wild. It seems to me that a "yew style" should be possible: a form that reflects the natural look of an old, enduring yew in the wild. This idea is a new one to me, but I hope to be able to contribute to its development.
Let me leave you with a few more pictures of yew bonsai, to encourage your interest.
