All parts of the plant, except the flesh of the fruit, are highly poisonous, having a paralyzing affect on the heart[1, 4, 7, 10, 19, 65].
Range
Europe, incl Britain, from Scandanavia south and east to N. Africa, the Caucasus, Iran, Himalayas.
Habitat
Woods and scrub, usually on limestone. It sometimes forms pure stands in sheltered sites on chalk in the south-east and on limestone in the north-west[17].

Physical Characteristics
An evergreen Tree growing to 15m by 10m at a slow rate.
It is hardy to zone 6 and is frost tender. It is in leaf all year, in flower from March to April, and the seeds ripen from September to November. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by Wind.
The plant is not self-fertile.
It is noted for attracting wildlife.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in heavy clay soil.
The plant prefers acid, neutral and basic (alkaline) soils and can grow in very acid and very alkaline soils.
It can grow in full shade (deep woodland) semi-shade (light woodland) or no shade.
It requires dry or moist soil and can tolerate drought.
The plant can tolerates strong winds but not maritime exposure.
It can tolerate atmospheric pollution.
Fruit - raw[1, 2, 65, 81, 158]. Very sweet and gelatinous, most people find it delicious though some find it sickly[K]. A number of people who like the flavour do not like the texture which is often described as being 'snotty'[K]. All other parts of this plant, including the seed, are highly poisonous. When eating the fruit you should spit out the large seed found in the fruit's centre. Should you swallow the whole seed it will just pass straight through you without harm. If it is bitten into, however, you will notice a very bitter flavour and the seed should immediately be spat out or it could cause some problems. The fruit is a fleshy berry about 10mm in diameter and containing a single seed[200].
Some reports suggest using the bark as a tea substitute[158, 183], this would probably be very unwise.
Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants.
Always seek advice from a professional before using a plant medicinally.
The yew tree is a highly toxic plant that has occasionally been used medicinally, mainly in the treatment of chest complaints. Modern research has shown that the plants contain the substance 'taxol' in their shoots. Taxol has shown exciting potential as an anti-cancer drug, particularly in the treatment of ovarian cancers[238]. Unfortunately, the concentrations of taxol in this species are too low to be of much value commercially, though it is being used for research purposes[238]. This remedy should be used with great caution and only under the supervision of a qualified practitioner[21]. See also the notes above on toxicity.
All parts of the plant, except the fleshy fruit, are antispasmodic, cardiotonic, diaphoretic, emmenagogue, expectorant, narcotic and purgative[7, 21]. The leaves have been used internally in the treatment of asthma, bronchitis, hiccup, indigestion, rheumatism and epilepsy[240, 257]. Externally, the leaves have been used in a steam bath as a treatment for rheumatism[257].
A homeopathic remedy is made from the young shoots and the berries[4]. It is used in the treatment of many diseases including cystitis, eruptions, headaches, heart and kidney problems, rheumatism etc[4].
Very tolerant of trimming, this plant makes an excellent hedge[1, 11, 29]. The plants are often used in topiary and even when fairly old, the trees can be cut back into old wood and will resprout[200]. One report says that trees up to 1000 years old respond well to trimming[200].
A decoction of the leaves is used as an insecticide[46, 61].
Some cultivars can be grown as a ground cover when planted about 1 metre or more apart each way[208]. 'Repandens' has been recommended[208].
Wood - heavy, hard, durable, elastic, takes a good polish but requires long seasoning. Highly esteemed by cabinet makers, it is also used for bows, tool handles etc[4, 7, 11, 46, 61, 66, 146]. It makes a good firewood[6].
The wood is burnt as an incense[146].
Cultivation details
A very easy plant to grow, it is extremely tolerant of cold and heat, sunny and shady positions, wet and dry soils, exposure and any pH[200]. Thrives in almost any soil, acid or alkaline, as long as it is well-drained[1, 11, 200]. Grows well in heavy clay soils. Sensitive to soil compaction by roads etc[186, 200]. Very shade tolerant[17, 81]. Tolerates urban pollution[200]. In general they are very tolerant of exposure, though plants are damaged by severe maritime exposure[K].
A very cold hardy plant when dormant, tolerating temperatures down to about -25°c[200]. The fresh young shoots in spring, however, can be damaged by frosts[186, K].
Plants are dioecious, though they sometimes change sex and monoecious trees are sometimes found[81, 186]. Male and female trees must be grown if fruit and seed is required[K]. The fruit is produced mainly on the undersides of one-year old branches[200].
A very long lived tree[1, 7, 11, 185], one report suggests that a tree in Perthshire is 1500 years old, making it the oldest plant in Britain. Another report says that trees can be up to 4000 years old[11]. It is, however, slow growing and usually takes about 20 years to reach a height of 4.5 metres[186]. Young plants occasionally grow 30cm in a year but this soon tails off and virtually no height increase is made after 100 years[185].
A very ornamental tree, there are many named varieties[200].
Very resistant to honey fungus[8, 88, 200], but susceptible to phytopthera root rot[81, 88].
The bark is very soft and branches or even the whole tree can be killed if the bark is removed by constant friction such as by children climbing the tree[186].
Plants produce very little fibrous root and should be planted in their final positions when still small[200].
The fruit is greatly relished by thrushes[186].
Propagation
Seed - can be very slow to germinate, often taking 2 or more years[78, 80]. It is best sown as soon as it is ripe in the autumn when it should germinate 18 months later. Stored seed may take 2 years or more to germinate. 4 months warm followed by 4 months cold stratification may help reduce the germination time[113]. Harvesting the seed 'green' (when fully developed but before it has dried on the plant) and then sowing it immediately has not been found to reduce the germination time because the inhibiting factors develop too early[80]. Prick out the seedlings into individual pots once they are large enough to handle and grow them on in pots in a cold frame. The seedlings are very slow-growing and will probably require at least 2 years of pot cultivation before being large enough to plant out. Any planting out is best done in late spring or early summer, after the last expected frosts[K].
Cuttings of half-ripe terminal shoots, 5 - 8cm long, July/August in a shaded frame. Should root by late September but leave them in the frame over winter and plant out in late spring[78]. High percentage[11].
Cuttings of ripe terminal shoots, taken in winter after a hard frost, in a shaded frame[113].
Cultivars
'Fastigiata'
A slow-growing female form of columnar habit, eventually reaching a height of perhaps 15 metres in western Britain, though it is lower and squatter in the east of the country[11]. The plant occasionally bears some male flowers and the occasional seedlings that are produced as a result of self-fertilization are usually of similar habit to the parent[11]. Otherwise seedlings produced from cross fertilization usually follow the growth habit of the male[11].
'Fructo-luteo'
Very similar in habit to the type species, differing mainly in having very attractive orange fruits[11]. These frits are of good quality and are usually produced in abundance[K].
'Hesseii'
Forms a spreading shrub about 5 metres tall and wide.
Bears heavy crops of firm, well-flavoured fruits, though there is sometimes a slightly bitter aftertaste.
'Nidiformis'
A small specimen of this plant, 1.2 metres tall, was seen at Hilliers Arboretum in September 1994. It had a large crop of sweet fruits, though they were somewhat smaller than average[K].
'Repandens'
A semi-prostrate female form eventually forming an undulating mass up to 75cm tall and 4.5 metres wide[11]. It makes an excellent ground cover[11].

I have long been an avid gardener, focusing on the use of native plants rather than ornamental varieties. I am also an experienced outdoorsman with a wide range of survival skills, including the use of edible plants and insects. You mentioned the fruit of Taxus baccata as being edible, but every written resource I have come across treats all parts of this plant as extremely poisonous. I currently collect 47 indigenous edible fungi and plants and would not mind adding yew berries to my repertoire. But first, of course, I need to do further research on the subject. Can you point me in the right direction? My e-mail address is NakedmanJG@yahoo.com. Thank-you, John.

Apparently its only the seeds of the plants which are poisionious
the fleshy parts of the fruit are fine. Our database entry says
All parts of the plant, except the flesh of the fruit, are highly poisonous, having a paralyzing affect on
the heart.
When eating the fruit you should spit out the large seed
found in the fruit's centre. Should you swallow the whole seed it will just pass straight through you without harm. If it is

I can vouch for the fact that the fleshy part of Yew (Taxus) fruit is edible.
As far as I know, all other parts of the plants, including the large single
seeds are poisonous. Not a major food source, I'd say, but the large seeds
are easy to spit out and the fleshy part is mildly sweet and juicy--a good
trail nibble.

I see you, and other readers, recommend eating the fleshy cup surrounding the yew berry. I too eat them from time to time just for fun, but please note what it says in _British Poisonous Plants_, HMSO Bulletin 161, 1968 (1976).
"The cup is attractive to children...the juicy part is sweet and not very poisonous..." (p.30, para 2.) Note "not _very_ poisonous". But farther down the page, we find
"Children have died from eating the cups." (p.30, para 4.) The book is concerned principally with toxicity to livestock, so I imagine it's a question of small children having rather less body mass than sheep!
Perhaps a word of warning would be sensible?
Best wishes, and keep up the excellent work.

I am befuddled, probably because of my ignorance on the subject; about Taxus Baccata being such a widespread ornamental if it is so poisonous, particularly to children. The only empirical explanation, if not very reassuring, is that even children would not go about snacking on a Taxus. Where I live Taxus Baccata is widely used as a hedge and I have been lovingly tending to one at home for the past 3 years, it’s coming along gorgeous, the hedge is about 2 meters tall already. It is a little sparse; I’m yet to really make it thicken up.
Today I learned about its toxicity and I am terrified because I have 2 and 5 year old children at home!?…
Please, can anybody shed some light, offer any guidance? I have considered chopping it all off…

how old are young plants beforethey bear fruit
Taxus baccata
Ken Fern
Fri Oct 20 2006
The time it takes for a young plant to commence fruiting is very variable, and also depends upon whether the young plant was started from seed or was produced vegetatively (cuttings).
We have had a seedling commence fruiting when only 8 years old, but this, I feel, is exceptional. Most of the seedlings I have grown have taken 10 - 15 years or even longer before flowering.
Named cultivars, which are produced vegetatively, should take less time.
Please also remember that plants are either male or female - if you have a male plant it will never bear fruit.

Msg for Jill Rixon - No, don't compost your yew clippings, donate them for scientific research in curing cancer!
Msg for Oscvar - Don't panic your Yew hedge will be fine just don't let your kids eat it!

I quote from
The foliage and seeds contain several alkaloids, in particular taxine, very poisonous, which alters to hydrotaxine by hydrolysis. Also one glucoside, taxicatine. The wood, bark, foliage and seeds are toxic. The foliage is the principal source of taxine. Old and desiccated foliage are more poisonous than young and fresh foliage. Poisoning is frequent in animals. Horses, asses and mules are extremely sensitive and can be killed in less than one hour. Rabbits, guinea-pigs and cats are insensitive to taxine. In humans, the yew generates digestive, nervous, respiratory and cardiovascular disorders which can result in death. Symptoms include excitation, hyperventilation, and tachycardia, followed by deceleration of the heart, hypotension, nausea, stomach pains, cramps, giddinesses, colic, violent diarrhoea, dizzy spells, convulsions, coma and death.
The red aril surrounding the seed can be eaten just as it is like delicacy with the proviso of not chewing the seed. It is sweetened and very mucilagineux. The arilles, removed from their seeds, have diuretic and laxative effects (L'Herbier Virtuel).

Yew is fine to compost, it just takes quite a bit longer to break down and it's best to put it in a separate pile for a year, watering occasionally,before adding it to the main heap (the same can apply to most evergreens). If you shred it, stand upwind from the shredder and wear gloves and eye protection, just in case. However, there are 2 companies that will collect yew clippings: the clippings have to be a year old, not more. The main one is called Friendship Estates Ltd, the other is Limehurst ltd. Parents with young children around yew are not faced with a serious danger: a well clipped yew hedge will produce very few, if any berries, while a yew tree won't really produce berries until it is far too tall for a toddler to get them. Older kids must be educated about berries and mushrooms, especially in the country.
