Taxus canadensis is a evergreen tree found in areas such as Eastern N. America - Newfoundland to Western Virginia, Manitoba, Kentucky and Iowa. A member of the Taxaceae family, Taxus canadensis Marshall is also known by its common name of Canadian Yew. The tree can grow to a height of 1.5 meters and up to 1.5 meters wide. The preferred habitat of Rich woods and thickets., with LMH soil and FSN moisture levels. .
Canadian Yew is a zone 4 hardy plant that has medicinal uses - the medicinal usage rating of Canadian Yew is 4The Canadian yew is a very poisonous plant, though it was employed medicinally by several native North American Indian tribes who used minute amounts of the leaves both internally and externally in order to treat a variety of complaints including rheumatism, fevers, influenza, expelling afterbirth and dispelling clots[213, 222, 257]. Modern research has shown that it contains the substance 'taxol' in its shoots and bark. Taxol has shown exciting potential as an anti-cancer drug, particularly in the treatment of ovarian cancers[222, 238]. This remedy is very toxic and, even when used externally, should only be used under the supervision of a qualified practitioner. See also the notes above on toxicity. . The plant is abortifacient, analgesic, antirheumatic, antitumor, diaphoretic, diuretic, emmenagogue, febrifuge and pectoral.
Taxus canadensis is a non flowering plant which is pollinated by Wind.
Known hazards of the plant: All parts of the plant, except the flesh of the fruit, are highly poisonous[1, 4, 7, 10,
The plant has an edibility rating of 3Fruit - raw[43, 46, 61, 105]. Very sweet and gelatinous, most people find it delicious though some find it sickly[K]. The fruit is a fleshy berry about 8mm in diameter and containing a single seed. 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 the seed has been bitten into, however, it could cause some problems.
Cultivation tips: Thrives in almost any soil, acid or alkaline, as long as it is well-drained. Plants are very shade tolerant82]. This species is the most cold-hardy member of the genus - dormant plants will tolerate very heavy frosts though the young growth in spring can be damaged by a few degrees of frost. The plants produce very little fibrous root and should be planted in their final positions when still small. Plants in this genus are notably resistant to honey fungus. Dioecious. Male and female plants must be grown if seed is required. Another report says that this species has monoecious flowers (separate male and female flowers, but both borne on the same plant).
. The plant should best be propagated by 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. 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. 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 - 8 centimeters 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. High percentage. Cuttings of ripe terminal shoots, taken in winter after a hard frost, in a shaded frame.
