DAY LILY

A daylily or day lily is a flowering plant in the genus Hemerocallis, a member of the family Asphodelaceae, subfamily Hemerocallidoideae. Despite the common name, it is not in fact a lily.

Gardening enthusiasts and horticulturists have long bred daylily species for their attractive flowers. Thousands of cultivars have been registered by local and international Hemerocallis societies. Daylilies are perennial plants, whose name alludes to its flowers, which typically last about a day.

ST JOHN'S WORT

Hypericum perforatum, also known as St John's wort, is a flowering plant species of the genus Hypericum and a medicinal herb that is sold over-the-counter as a treatment for depression. Other names for it include Tipton's weed, rosin rose, goatweed, chase-devil, or Klamath weed. With qualifiers, St John's wort is used to refer to any species of the genus Hypericum. Therefore, H. perforatum is sometimes called common St John's wort or perforate St John's wort to differentiate it.

Hypericum is classified in the family Hypericaceae, having previously been classified as Guttiferae or Clusiaceae. Approximately 370 species of the genus Hypericum exist worldwide with a native geographical distribution including temperate and subtropical regions of Europe, Turkey, Ukraine, Russia, Middle East, India, and China.

St John's wort is a perennial plant with extensive, creeping rhizomes. Its stems are erect, branched in the upper section, and can grow to 1 m high. It has opposing, stalkless, narrow, oblong leaves that are 12 mm long or slightly larger. The leaves are yellow-green in colour, with transparent dots throughout the tissue and occasionally with a few black dots on the lower surface. Leaves exhibit obvious translucent dots when held up to the light, giving them a ‘perforated’ appearance, hence the plant's Latin name.

Its flowers measure up to 2.5 cm across, have five petals, and are coloured bright yellow with conspicuous black dots. The flowers appear in broad cymes at the ends of the upper branches, between late spring and early to mid summer. The sepals are pointed, with glandular dots in the tissue. There are many stamens, which are united at the base into three bundles. The pollen grains are ellipsoidal. When flower buds (not the flowers themselves) or seed pods are crushed, a reddish/purple liquid is produced.

CAMPANULA

Campanula is one of several genera in the family Campanulaceae with the common name bellflower. It takes both its common and its scientific name from its bell-shaped flowers —campanula is Latin for "little bell". The genus includes over 500 species and several subspecies, distributed across the temperate and subtropical regions of the Northern Hemisphere, with the highest diversity in the Mediterranean region east to the Caucasus.

Campanula persicifolia (peach-leaved bellflower, shown here) is a herbaceous perennial growing to 1 m. Its flowers are cup-shaped and can be either lilac-blue or white. Its foliage is narrow and glossy with a bright green appearance. It is common in the Alps and other mountain ranges in Europe. It grows at lower altitudes in the north, and higher up further south, passing 1,500 m in Provence.

Normally it flowers in June; a dry summer may reduce or inhibit its flowering. Despite this it can flower as late as September in a cold year. The natural habitat of this plant is broad-leaved forests, woodland margins, rocky outcrops in broad-leaved woods, meadows and banks.

ICELAND POPPY

The Iceland Poppy (Papaver nudicaule, syn. Papaver croceum, P. miyabeanum, P. amurense, and P. macounii) is a boreal flowering plant. Native to subpolar regions of Europe, Asia and North America, and the mountains of Central Asia (but not in Iceland), Iceland poppies are hardy but short-lived perennials, often grown as biennials, that yield large, papery, bowl-shaped, lightly fragrant flowers supported by hairy, one foot, curved stems among feathery blue-green foliage.

They were first described by botanists in 1759. The wild species blooms in white or yellow, and is hardy from USDA Zones 3a-10b. All parts of this plant are likely to be poisonous, containing (like all poppies) toxic alkaloids. In particular, P. nudicaule has been shown to contain the benzophenanthidine alkaloid, chelidonine.

SHASTA DAISIES

Leucanthemum × superbum (or Shasta daisy) is a commonly grown flowering herbaceous perennial plant with the classic daisy appearance of white petals (ray florets) around a yellow disc, similar to the oxeye daisy Leucanthemum vulgare Lam. but larger. Shasta daisies are characterised by a distinct odour which some find unpleasant.

This flower originated as a hybrid produced in 1890 by the American horticulturist Luther Burbank from a number of daisies. First, he crossed Leucanthemum vulgare with Leucanthemum maximum (Ramond) DC.; this double hybrid was itself crossed with Leucanthemum lacustre (Brot.) Samp. The resulting Leucanthemum triple hybrid was crossed with Nipponanthemum nipponicum (Franch. ex Maxim.) Kitam., creating an intergeneric cross of species from three continents.

It was named after Mount Shasta, because its petals were the colour of the snow. Some members of the genus are considered noxious weeds, but the Shasta daisy remains a favourite garden plant and ground-cover. Many cultivars are suitable for cut flowers, such as 'Becky', 'Esther Read', 'Silberprinzesschen' (Silver Princess), 'Snow Lady', 'Tinkerbell', 'Wirral Pride', 'Wirral Supreme'. The cultivar 'T.E. Killin' has gained the Royal Horticultural Society's Award of Garden Merit. The illustrated variety is 'Snowdrift', which we have growing in our garden.

IRIS

Iris is a genus of about 300 species of flowering plants with showy flowers. It takes its name from the ancient Greek goddess of the rainbow, Iris, referring to the wide variety of flower colours found among the many species. As well as being the scientific name, iris is also very widely used as a common name for all Iris species, though some plants called thus belong to other closely related genera. A common name for some species is 'flags', while the plants of the subgenus Scorpiris are widely known as 'junos', particularly in horticulture. 

It is a popular garden flower and its blossoms provide wonderful splashes of colour in the Spring garden. The genus is widely distributed throughout the north temperate zone. Their habitats are varied, ranging from cold and montane regions to the grassy slopes, meadowlands and riverbanks of Europe, the Middle East and northern Africa, Asia and across North America. Irises are perennial herbs, growing from creeping rhizomes (rhizomatous irises) or, in drier climates, from bulbs (bulbous irises). They have long, erect flowering stems which may be simple or branched, solid or hollow, and flattened or have a circular cross-section. The rhizomatous species usually have 3–10 basal sword-shaped leaves growing in dense clumps. The bulbous species have cylindrical, basal leaves.

ROCKY DAISY

Brachyscome multifida is a perennial herb in the family Asteraceae. Common names include Cut-leaved Daisy, Rocky Daisy, and Hawkesbury Daisy. The species is endemic to Australia. This species has an erect, matting growth habit growing to 45 cm in height. The foliage is fine and deeply divided, The flowerheads arise above the foliage on 4 to 40 cm long peduncles. The ray florets are mauve, pink or white and are 7 to 10 mm long. The plants main flowering season is early autumn to mid winter, but the daisy-like flowerheads may appear throughout the year.

Brachyscome multifida occurs on dry, shallow or rocky soils in sclerophyll forest or grassland in Victoria, New South Wales and Queensland. The species and its cultivars are popular in horticulture, and are used for mass plantings, in hanging baskets, in borders and spilling over retaining walls. They can be grown in a wide range of soils and tolerate dry conditions, but will benefit from supplementary watering. Plants are best situated in a position with full sun, although partial shade is tolerated. Although relatively frost tolerant, foliage may burn.The plants is readily propagated by cuttings which strike readily. Plants may also be propagated by layering or from seed, though germination rate is usually poor.

ARMERIA

Armeria is a genus of flowering plants in the Plumbaginaceae family. These plants are sometimes known as "lady's cushion", "thrift", or "sea pink" (the latter because as they are often found on coastlines). The genus counts over a hundred species, mostly native to the Mediterranean, although Armeria maritima is an exception, being distributed along the coasts of the Northern Hemisphere, including Ireland, parts of the United Kingdom such as Cornwall, and the Pembrokeshire Coast National Park in Wales. Some are popular with gardeners as rockery plants.

The garden hybrid illustrated here is Armeria 'Bees Ruby', which is a delightful clump forming evergreen plant ideal for edging, container culture or simply adding colour to the front of garden beds and rockeries. Tall, leafless stems of deep cerise coloured flowers cluster together to form impressive round globes from late winter through spring which last well if cut for fresh posies. The attractive foliage comprises of broader leaves than normally found in this family providing an interesting textural presence year round.

Armerias are a hardy perennial found in a range of soil types and climatic conditions around the world ranging from storm-swept coastal zones through to alpine meadows. They prefer a full sun position in a friable, well drained soil. Although dry tolerant once established occasional deep watering through extended periods of heat will maintain a more robust performance. No pruning required although removing spent flower stems will encourage further displays. Feed with a slow release fertiliser in spring.

BILLBERGIA

Billbergia is a genus of flowering plants in the family Bromeliaceae, subfamily Bromelioideae. The genus, named for the Swedish botanist, zoologist, and anatomist Gustaf Johan Billberg, is divided into two subgenera: Billbergia and Helicodea. They are native to forest and scrub, up to an altitude of 1,700 m, in southern Mexico, the West Indies, Central America and South America, with many species endemic to Brazil.

They are rosette-forming, evergreen perennials, usually epiphytic in habit, often with brilliantly coloured flowers. The cultivar shown here is Billbergia 'Muriel Waterman' that was hybridised by the great American collector and enthusiast, Mulfor Foster, and introduced in 1946. The stout tubular rosette, is about 7.5 cm in diameter, opens out to a funnel at the top of some six to eight leaves. These are rose-maroon with transverse silver bands, making it one of the most colourful foliage billbergias. The showy flower spike consists of long pink bracts and striking blue flowers.

ECHIUM

Echium candicans (syn. Echium fastuosum J.Jacq.), commonly known as pride of Madeira, is a species of flowering plant in the family Boraginaceae, native to the island of Madeira. It is a large herbaceous perennial subshrub, growing to 1.5–2.5 m. In the first year after germination the plant produces a broad rosette of leaves. In the second and subsequent years more or less woody flowering stalks are produced clothed in rough leaves. The flower head is large and covered with blue flowers having red stamens. It is much visited by bees and butterflies for its nectar.

Echium candicans is cultivated in the horticulture trade and widely available throughout the world as an ornamental plant for traditional and drought tolerant water conserving gardens. It is particularly suitable for coastal planting, and is a popular ornamental in coastal California. With a minimum temperature requirement of 5–7 °C, in frost-prone areas it needs some winter protection. It has gained the Royal Horticultural Society's Award of Garden Merit.

In California, it is also an invasive species. It is removed from native plant communities as part of habitat restoration efforts in coastal parks such as the Golden Gate National Recreation Area. In New Zealand it is a common garden escape onto road-side verges and shingle banks throughout the drier parts of the two principal islands. In the state of Victoria, Australia, it is considered to be a high weed risk and an alert has been posted by the Department of Primary Industries.

KANGAROO PAWS

Anigozanthos is a small genus of Australian plants in the Bloodwort family Haemodoraceae. The 11 species and several subspecies are commonly known as kangaroo paw and catspaw depending on the shape of their flowers. A further species, previously identified as Anigozanthos fuliginosus and commonly known as the black kangaroo paw, has been transferred to its own monotypic genus and is now known as Macropidia fuliginosa.

The genus was first named by Jacques Labillardière in his work, Relation du Voyage à la Recherche de la Pérouse, issued in 1800. The French botanist collected and described the type species, Anigozanthus rufus, during the d'Entrecasteaux expedition's visit to Southwest Australia in 1792. In recent years a number of numerous hybrids and cultivars have been developed. Kangaroo paws are much in demand as house plants and as cut flowers.

These perennials are endemic to dry sandy, siliceous areas of southwest Australia, but they occur as well in a variety of other environments and soil types. They are grown commercially in Australia, the United States, Japan and Israel. The plant grows from short, underground, horizontal rhizomes. The length and the character of these may vary between the species: some are fleshy, others are fragile. The sap in the root system allows the plants to survive extreme dry spells. In summer, a number of species die back to the rhizome, growing back in autumn.

The tuberous flower buds are covered with coloured hairs, giving them a velvety aspect. These long furry hairs also determine the colour of the flower, which may range from almost black to yellow, orange and red. Some species are even dichromatic (as Anigozanthos manglesii). The tubular form of the flower bud resembles a kangaroo paw, hence its name. The flower tip spreads fanlike into six petals. Full-grown plants can have up to ten flowers at the end of each stalk.
