Botanical Name: Potentilla glandulosa
Family: Rosaceae
Subfamily: Rosoideae
Genus: Drymocallis
Species: D. glandulosa
Kingdom: Plantae
Order: Rosales

Synonyms: Potentilla glandulosa Lindl.

Common Names: Gland Cinquefoil, Sticky cinquefoil, Arizona cinquefoil, Ashland cinquefoil, Ewan’s cinquefoil, Hans

Habitat : Potentilla glandulosa is native to western North America from southwestern Canada through the far western United States and California, into Baja California. It grows on Rocky hillsides, Black Hills on Sioux quartzite in eastern South Dakota. It is widespread and can be found in many types of habitats.

Description:
Potentilla glandulosa is a perennial herb. It is generally erect in form but it may be small and tuftlike, measuring just a few centimeters high, or tall and slender, approaching 1 metre (3.3 ft) in height. It may or may not have rhizomes. It is usually coated in hairs, many of which are glandular, giving the plant a sticky texture. The leaves are each divided into several leaflets, with one long terminal leaflet and a few smaller ones widely spaced on each side.

The inflorescence is a cyme of 2 to 30 flowers which are variable in color and size. Each has usually five petals up to a centimeter long which may be white to pale yellow to gold. It is in flower from Jun to August. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.The plant is self-fertile.

Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.

Cultivation:
Easily grown in a well-drained loam, preferring a position in full sun but tolerating shade. Prefers an alkaline soil but tolerates a slightly acid soil. Members of this genus are rarely if ever troubled by browsing deer.

Propagation:
Seed – sow early spring or autumn in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division in spring. Larger divisions can be planted out direct into their permanent positions. We have found that it is better to pot up the smaller divisions and grow them on in light shade in a cold frame until they are well established before planting them out in late spring or early summer.

Edible Uses: Tea.
A tea-like beverage is made by boiling the leaves or the whole plant in water.
Medicinal Uses:

Astringent; Stimulant; Tonic.

All parts of the plant are astringent. An infusion has been drunk, and a poultice of the plant applied externally in the treatment of swollen parts. An infusion of the plant has been used as a stimulant and tonic.

Species: Helianthemum nummularium
Kingdom: Plantae
Order: Malvales

Synonyms: Helianthemum chamaecistus. Mill. Helianthemum vulgare. Gaertn.

Common Names:, Common Rockrose, Sun Rose, Rock Rose

Habitat: Helianthemum nummularium is native to most of Europe. It grows on the basic grassland and scrub, to 600 metres.

Description:
Helianthemum nummularium is an evergreen tralling Shrub growing to 0.5 m (1ft 8in) by 1 m (3ft 3in) at a fast rate.
It is plant with loose terminal clusters of bright yellow, saucer-shaped flowers. In the flower centre is a tight cluster of orange stamens, which are sensitive to the touch, and spread outwards to reveal the tall stigma in the middle. The plant is common on chalk downs, and occasional in other grasslands, always on dry, base-rich soil. The wild species has yellow flowers, but garden varieties range from white through yellow to deep red.

Though the individual blooms are short-lived, the plant produces a mass of flowers through the summer. It needs a dry, sunny place, like a south-facing rockery or meadow. As the Latin name Helianthemum suggests, these are sun-flowers. This is a good nectar source for bees and there are several species of small beetle that feed on the foliage. Common rock-rose is also the food plant for the larvae of several species of moth and butterfly.

It flowers from May until July.

Common Names: Fringed iris, Shaga or Butterfly flow

Habitat : Iris japonica is a native of China and Japan. It grows on woodland hills, grassy and rocky slopes and among rocks by streams.

Description:
Iris japonica is a rhizomatous perennial plant, with pale blue, lavender or white flowers with an orange or yellow crest. It is cultivated as an ornamental plant in temperate regions. It has wiry, stout stems, that can grow up to between 25–80 cm (10–31 in) tall. It has 5-12 short, slender branches, (or pedicels) near top of the plant. The stiff pedicels can reach between 1.5–2.5 cm (1–1 in) long. The flowering stem (and branches) grow higher than the leaves. The stems have 3-5 spathes (leaves of the flower bud), which are lanceolate, and 9.5–2.2 cm (4–1 in) long.

CLICK & SEE THE PICTURES

The flowers are like Iris cristata flowers but paler and fancier. The short lasting flowers open in succession (one after another), for between 2, and 5 weeks. These flowers have a clove pinks aroma.

The flattish, flowers are 4.5–6 cm (2–2 in) in diameter, and come in shades of pale blue, or pale lavender, or lilac, or purple, to white.

It has 2 pairs of petals, 3 large sepals (outer petals), known as the ‘falls’ and 3 inner, smaller petals (or tepals, known as the ‘standards’). The falls are elliptic or obovate, with a spreading limb and blue or purple/violet blotching, spots, (or dots) around a central yellow signal patch around a visible yellow, or orange crest. They are 2.5–3 cm (1–1 in) long and 1.4–2 cm wide. The standards are elliptic or narrowly obovate. They are 2.8–3 cm (1–1 in) long and 1.5-2.1 cm wide. The standards spreading to the same plane as the falls, creating the ‘flat’ look. All the petals are fringed (fimbriated) around the edges.

It has a 1.1–2 cm long perianth tube, 0.8-1.2 cm long stamens, white anthers and 7-10mm ovary. It has 0.5-0.75 long and pale blue style branches. The terminal lobes are fimbriated (fringed).

After the iris has flowered, between May and June, it produces an ellipsoid-cylindric, non-beaked seed capsule, which is 2.5–3 cm long and 1.2-1.5 cm wide. Inside the capsule, it has dark brown seeds with a small aril.

Cultivation:
Prefers a gritty well-drained soil with plenty of moisture in summer and shelter from early morning sun. Prefers a lime-free soil but succeeds in most good soils. Succeeds in full sun or partial shade, but plants flower better in a hot sunny position. Established plants are drought tolerant. Cultivated for its edible root in Japan. A number of named varieties have been selected for their ornamental value. It is best to lift the plant in October, store in sand in a cool frost-free place over winter and plant out in March. Plants have creeping aerial rhizomes that root at intervals. The flowers are susceptible to damage by late frosts, the plants failing to flower after an exceptionally cold winter. Members of this genus are rarely if ever troubled by browsing deer or rabbits.

Propagation :
Seed – best sown as soon as it is ripe in a cold frame. Stored seed should be sown as early in the year as possible in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse or cold frame for their first year. Plant out into their permanent positions in late spring or early summer. Division, best done after flowering in July/August. Very easy, larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.

Edible Uses :
Edible Parts: Root.

Root – the source of an edible starch. Some caution is advised, see the notes below on toxicity.
Medicinal Uses:

The rhizome is used in the treatment of injuries. A decoction of the plant is used in the treatment of bronchitis, internal injuries, rheumatism and swellings.

Other Uses :
Plants can be grown for ground cover when planted about 45cm apart each way.

Known Hazards: Many plants in this genus are thought to be poisonous if ingested, so caution is advised. The roots are especially likely to be toxic. Plants can cause skin irritations and allergies in some people.

Botanical Name :Agalinis tenuifolia
Family: Orobanchaceae
Genus: Agalinis
Species: A. tenuifolia
Kingdom: Plantae
Order: Lamiales

Synonyms : Gerardia tenuifolia – Vahl.

Common Names: Common gerardia, Slender false foxglove, Common false foxglove

Habitat :Agalinis tenuifolia is native to the eastern and southwestern United States, and Canada, which produces purple flowers in late summer or early fall. It grows in moist open areas and low woods in Texas.

Description:

Agalinis tenuifolia is a perennial plant .It is erect, annual, 8″-24″ tall forb, dark green, blackish when dry, many erect branches; stems smooth.Individual flowers and their buds are produced from the axils of the leaves on the upper and outer stems; these flowering stems can be regarded as leafy racemes. The swollen flower buds are conspicuously white. Each flower is about ½–¾” across, consisting of a short tubular corolla with 5 petal-like lobes and a tubular calyx with 5 short teeth. The corolla is pink, purplish pink, or medium purple; its 5 rounded lobes are quite large in relation to its tubular base. The lobes are finely ciliate along their margins. The lower interior of the corolla has dark purple spots and a pair of faint yellow lines. Near the upper interior of the corolla, there are 4 stamens with hairy white anthers and an undivided white style (sometimes with a pale yellow tip). The slender pedicels of the flowers are green to reddish purple; they are usually as long or longer than the flowers (at least ½” long). The blooming period occurs during the late summer or early fall and lasts about 2-3 weeks. Each flower lasts only a day or two before its corolla falls to the ground. There is no noticeable floral scent. Each flower is replaced by a globoid seed capsule containing many small seeds that can be blown about by the wind. The root system is fibrous. Slender False Foxglove is partially parasitic on other plants.
