It grows easily in alkaline and saline soils, and thrives on soils that are rich in calcium. It rapidly establishes in disturbed habitat, including burns, flooded washes, and rockslides, so it is a valuable shrub for revegetating damaged land such as overgrazed rangeland and abandoned mining areas. This shrub grows up to about 1.5 meters in height with spreading brittle pale-colored stem branches. The leaves are up to a few centimeters long and may be thin and thready or up to a centimeter wide and oblong in shape. They are glandular, resinous, and sticky. The inflorescence is a bushy cluster of flower heads, each head one half to one centimeter long. The flower head is lined with sticky yellow-green phyllaries and contains several yellowish protruding flowers. The fruit is a hairy achene a few millimeters long with a wispy pappus at the tip.

It is hardy to zone 3. It is in flower from July to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.
The plant prefers light (sandy) and medium (loamy) soils, requires well-drained soil and can grow in nutritionally poor soil. The plant prefers acid, neutral and basic (alkaline) soils and can grow in very alkaline soil. It cannot grow in the shade. It requires dry or moist soil and can tolerate drought.

Cultivation:
Requires a sunny position and prefers a well-drained sandy soil. Plants do not require a rich soil. They tolerate alkaline soils. A very hardy plant but it prefers a drier climate than it finds in Britain though it succeeds in this country if given the protection of a dry sunny wall. A very variable and ornamental species[60]. The leaves and stems are pleasantly aromatic.

Propagation
Seed – we have no information for this species but suggest sowing the seed in spring in a greenhouse and only just covering the seed. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, July/August in sand in a frame.

Edible Uses
Edible Uses: Condiment; Gum.

A latex obtained from the root is used as a chewing gum. The plant has been used as a spice.

Medicinal Actions &  Uses
Antirheumatic; Odontalgic; Poultice.
A poultice made from the chewed plant tips has been applied to boils and rheumatic joints. An infusion of the leaves has been used to treat colds . The finely mashed leaves have been inserted in tooth cavities to treat toothache.

Other Uses
Dye; Latex.

The latex obtained from the roots could be used in making rubber. Unfortunately it is not produced in sufficient quantity to make commercial extraction worthwhile. A green dye is obtained from the bark. A yellow-gold dye is obtained from the flowers. It is orange when alum is used as a mordant.

Scented Plants
Leaves: Crushed
The leaves and stems are pleasantly aromatic when crushed.

Deltoid Balsamroot(Balsamorhiza deltoidea)

Botanical Name : Balsamorhiza deltoidea
Family : Compositae / Asteraceae
Genus : Balsamorhiza
Common Namedeltoid balsamroot.
Kingdom: Plantae
Order: Asterales
Tribe: Heliantheae
Species: B. deltoidea

Habitat : Western N. AmericaBritish Columbia to California.Open places but not on thin soils.


Description:

This is a taprooted perennial herb growing erect to a maximum height near 90 centimeters. The stems are hairy and glandular. The large leaves are up to 25 centimeters long and 20 wide, and are roughly triangular in shape, hairy and glandular, and often toothed along the edges. The inflorescence bears usually one or sometimes a few large flower heads, each lined with hairy, pointed phyllaries up to 4 centimeters long. The head has a center of yellowish disc florets and a fringe of pointed yellow ray florets each up to 4 or 5 centimeters long. The fruit is an achene 7 to 8 millimeters in length.

It is hardy to zone 5. It is in flower from May to June. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.

The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires dry or moist soil.

Cultivation:
Requires a deep fertile well-drained loam in full sun. Plants strongly resent winter wet. Hardy to at least -25°c. Plants are intolerant of root disturbance and should be planted into their permanent positions whilst still small.

Propagation:
Seed – sow early spring in a greenhouse and only just cover the seed. Germination usually takes place within 2 – 6 days at 18°c. Either sow the seed in individual pots or pot up the seedlings as soon as they are large enough to handle and plant them out into their permanent positions in the summer. Division in spring. Very difficult since the plant strongly resents root disturbance. It is probably best to take quite small divisions, or basal cuttings, without disturbing the main clump. Pot these up into individual pots and keep them in light shade in the greenhouse until they are growing away well. Plant them out in the summer if they have grown sufficiently, otherwise over-winter them in the greenhouse and plant out in late spring.

Edible Uses
Edible Parts: Leaves; Root; Seed.

Edible Uses: Coffee.

Root – raw or cooked. A sweet taste when cooked[161]. Young shoots – raw. Seed – raw or cooked. It can be ground into a powder and made into a bread. The ground seeds can be formed into cakes and eaten raw. The roasted root is a coffee substitute.

Medicinal Uses:
Miscellany.
A decoction of the split roots has been used in the treatment of coughs and colds.
