Summary
Bloom Color: Yellow. Main Bloom Time: Early spring, Late spring, Mid spring. Form: Oval, Pyramidal.
Physical Characteristics
Pinus coulteri is an evergreen Tree growing to 18 m (59ft) by 7 m (23ft) at a medium rate.
See above for USDA hardiness. It is hardy to UK zone 8. It is in leaf all year, in flower in June, and the seeds ripen from January to February. The species is monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and is pollinated by Wind. The plant is not self-fertile.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils, prefers well-drained soil and can grow in heavy clay and nutritionally poor soils. Suitable pH: mildly acid and neutral soils. It cannot grow in the shade. It prefers dry or moist soil and can tolerate drought.

Edible Uses
Edible Parts: Seed
Edible Uses: Condiment
Seed - raw or cooked[2, 62, 63, 92, 182]. Large[183], individual seeds are up to 15mm x 8mm[200]. The oil-rich seed has a delicious taste with a slightly resinous flavour, it used to be gathered in large quantities by the local Indians who ate it as a staple food[82]. A vanillin flavouring is obtained as a by-product of other resins that are released from the pulpwood[200].

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 turpentine obtained from the resin of all pine trees is antiseptic, diuretic, rubefacient and vermifuge[4]. It is a valuable remedy used internally in the treatment of kidney and bladder complaints and is used both internally and as a rub and steam bath in the treatment of rheumatic affections[4]. It is also very beneficial to the respiratory system and so is useful in treating diseases of the mucous membranes and respiratory complaints such as coughs, colds, influenza and TB[4]. Externally it is a very beneficial treatment for a variety of skin complaints, wounds, sores, burns, boils etc and is used in the form of liniment plasters, poultices, herbal steam baths and inhalers[4].

Other Uses
Dye Herbicide Wood
Landscape Uses:Aggressive surface roots possible, Screen, Specimen. A tan or green dye is obtained from the needles[168]. The needles contain a substance called terpene, this is released when rain washes over the needles and it has a negative effect on the germination of some plants, including wheat[201]. Oleo-resins are present in the tissues of all species of pines, but these are often not present in sufficient quantity to make their extraction economically worthwhile[64]. The resins are obtained by tapping the trunk, or by destructive distillation of the wood[4, 64]. In general, trees from warmer areas of distribution give the higher yields[64]. Turpentine consists of an average of 20% of the oleo-resin[64] and is separated by distillation[4, 64]. Turpentine has a wide range of uses including as a solvent for waxes etc, for making varnish, medicinal etc[4]. Rosin is the substance left after turpentine is removed. This is used by violinists on their bows and also in making sealing wax, varnish etc[4]. Pitch can also be obtained from the resin and is used for waterproofing, as a wood preservative etc. Wood - coarse-grained, light, soft, not strong. Occasionally used for fuel and second class lumber[82, 84, 229]. Special Features:
Attracts birds, Attractive foliage, North American native, Inconspicuous flowers or blooms. Heat zone: 9-8.

Cultivation details
Succeeds in most soils, including clay[81]. Prefers in a light well-drained sandy or gravelly loam[1, 11, 120]. Dislikes poorly drained moorland soils[1]. Established plants tolerate drought[200]. This species is not hardy in the colder areas of the country, it tolerates temperatures down to between -5 and -10°c[200]. A short-lived tree in Britain. It is slow to get established but it then grows strongly[120]. Of moderate growth in height with increases of about 30 - 40cm a year, but of rapid increase in girth, about 3 - 5cm a year[185]. Trees grow better in the southern part of the country[120]. Trees do not often bear cones in Britain[11, 81]. A tree planted in 1954 at Kew was about 12 metres tall in September 1993 and was carrying a number of large cones[K]. The summer had been cool and damp[K]. The same tree had another good crop of cones in the autumn of 1996 and continues to cone quite well in 1999[K]. An 11 year old tree at Kew had two small female cones in January 1999[K]. The fresh cones can weigh 2.2 kilos and when dried in a warm room for a year or so still weigh ½ kilo. The cones open and shed their seed whist still attached to the tree[226]. The seeds are ejected explosively from the dry cone over a period of several weeks[185]. The cones are 25 - 35cm long[82], they can hang on the tree for a number of years with their seed intact[81]. This species is closely related to P. sabiniana[229]. Leaf secretions inhibit the germination of seeds, thereby inhibiting the growth of other plants below the tree[18]. Plants are strongly outbreeding, self-fertilized seed usually grows poorly[200]. They hybridize freely with other members of this genus[200]. Plants in this genus are notably susceptible to honey fungus[200].

Plant Propagation
It is best to sow the seed in individual pots in a cold frame as soon as it is ripe if this is possible otherwise in late winter. A short stratification of 6 weeks at 4°c can improve the germination of stored seed[80]. Plant seedlings out into their permanent positions as soon as possible and protect them for their first winter or two[11]. Plants have a very sparse root system and the sooner they are planted into their permanent positions the better they will grow[K]. Trees should be planted into their permanent positions when they are quite small, between 30 and 90cm[200]. We actually plant them out when they are about 5 - 10cm tall. So long as they are given a very good weed-excluding mulch they establish very well[K]. Larger trees will check badly and hardly put on any growth for several years. This also badly affects root development and wind resistance[200]. Cuttings. This method only works when taken from very young trees less than 10 years old. Use single leaf fascicles with the base of the short shoot. Disbudding the shoots some weeks before taking the cuttings can help. Cuttings are normally slow to grow away[81].
