Dipsacus is a genus of flowering plant in the family Caprifoliaceae. The members of this genus are known as teasel, teazel or teazle. The genus includes about 15 species of tall herbaceous biennial plants (rarely short-lived perennial plants) growing to 1–2.5 metres (3.3–8.2 ft) tall. Dipsacus are native to Europe, Asia and northern Africa.
The genus name is derived from the word for thirst of water and refers to the cup-like formation made where sessile leaves merge at the stem. Rain water can collect in this receptacle; this may perform the function of preventing sap-sucking insects such as aphids from climbing the stem. A 2011 experiment has shown that adding dead insects to these cups increases the seed set of teasels (but not their height), implying partial carnivory. Carnivory in teasels was discussed by Francis Darwin (son of Charles Darwin) in a paper held by The Royal Society. The leaf shape is lanceolate, 20–40 centimetres (7.9–15.7 in) long and 3–6 centimetres (1.2–2.4 in) broad, with a row of small spines on the underside of the midrib.
Teasels are easily identified with their prickly stem and leaves, and the inflorescence of purple, dark pink or lavender flowers that form a head on the end of the stem(s). The inflorescence is ovoid, 4–10 centimetres (1.6–3.9 in) long and 3–5 centimetres (1.2–2.0 in) broad, with a basal whorl of spiny bracts. The first flowers begin opening in a belt around the middle of the spherical or oval flowerhead, and then open sequentially toward the top and bottom, forming two narrow belts as the flowering progresses. The dried head persists afterwards, with the small (4–6 millimetres (0.16–0.24 in)) seeds maturing in mid autumn.
The seeds are an important winter food resource for some birds, notably the European goldfinch. Teasels are often grown in gardens and encouraged on some nature reserves to attract them.
Teasel is also considered an invasive species in the United States. It is known to form a monoculture, capable of crowding out all native plant species, and therefore is discouraged and/or eliminated within restored open lands and other conservation areas.

Linum (flax) is a genus of approximately 200 species in the flowering plant family Linaceae. They are native to temperate and subtropical regions of the world. The genus includes the common flax (L. usitatissimum), the bast fibre of which is used to produce linen and the seeds to produce linseed oil.

Linum narbonenseThe flowers of most species are blue or yellow, rarely red, white, or pink, and some are heterostylous. There is an average of 6 to 10 seeds per boll.
Linum species are used as food plants by the larvae of some Lepidoptera species including the Cabbage Moth, The Nutmeg, the Setaceous Hebrew Character and Coleophora striolatella, which feeds exclusively on Linum narbonense.

Agapanthus /ˌæɡəˈpænθəs/ is the only genus in the subfamily Agapanthoideae of the flowering plant family Amaryllidaceae. The family is in the monocot order Asparagales. The name is derived from scientific Greek: αγάπη (agape) = love, άνθος (anthos) = flower.

Some species of Agapanthus are commonly known as lily of the Nile (or African lily in the UK), although they are not lilies and all of the species are native to Southern Africa (South Africa, Lesotho, Swaziland, Mozambique) though some have become naturalized in scattered places around the world (Australia, Great Britain, Mexico, Ethiopia, Jamaica, etc.).

Species boundaries are not clear in the genus, and in spite of having been intensively studied, the number of species recognized by different authorities varies from 6 to 10. The type species for the genus is Agapanthus africanus. A great many hybrids and cultivars have been produced and they are cultivated throughout warm areas of the world, and can especially be spotted all throughout Northern California. Most of these were described in a book published in 2004.

Agapanthus is a genus of herbaceous perennials that mostly bloom in summer. The leaves are basal and curved, linear, and up to 60 cm (24 in) long. They are arranged in two rows.
The inflorescence is a pseudo-umbel subtended by two large bracts at the apex of a long, erect scape, up to 2 m (6.6 ft) tall. They have funnel-shaped flowers, in hues of blue to purple, shading to white. Some hybrids and cultivars have colors not found in wild plants. The ovary is superior. The style is hollow. Agapanthus does not have the distinctive chemistry of Alliaceae.

A daylily is a flowering plant in the genus Hemerocallis /ˌhɛmᵻroʊˈkælɪs/. Gardening enthusiasts and professional horticulturalists have long bred daylily species for their attractive flowers. Thousands of cultivars have been registered by local and international Hemerocallis societies. Hemerocallis is now placed in family Asphodelaceae, subfamily Hemerocallidoideae, but used to be part of Liliaceae (which includes true lilies).
Daylilies are perennial plants, whose name alludes to the flowers which typically last no more than 24 hours. The flowers of most species open in early morning and wither during the following night, possibly replaced by another one on the same scape (flower stalk) the next day. Some species are night-blooming. Daylilies are not commonly used as cut flowers for formal flower arranging, yet they make good cut flowers otherwise as new flowers continue to open on cut stems over several days.
Hemerocallis is native to Eurasia, primarily eastern Asia, including China, Korea, and Japan. This genus is popular worldwide because of the showy flowers and hardiness of many kinds. There are over 60,000 registered cultivars. Hundreds of cultivars have fragrant flowers, and more scented cultivars are appearing more frequently in northern hybridization programs. Some cultivars rebloom later in the season, particularly if their capsules, in which seeds are developing, are removed.
Most kinds of daylilies occur as clumps, each of which has leaves, a crown, flowers, and roots. The long, linear lanceolate leaves are grouped into opposite fans with arching leaves. The crown is the small white portion between the leaves and the roots. Along the scape of some kinds of daylilies, small leafy "proliferations" form at nodes or in bracts. A proliferation forms roots when planted and is often an exact clone of its parent plant. Many kinds of daylilies have thickened roots in which they store food and water.

Kniphofia /nɪpˈhoʊfiə/, also called tritoma, red hot poker, torch lily, knofflers or poker plant, is a genus of flowering plants in the family Asphodelaceae, first described as a genus in 1794. It is native to Africa. Herbaceous species and hybrids have narrow, grass-like leaves 10–100 cm (4–39 in) long, while perennial species have broader, strap-shaped foliage up to 1.5 m (5 ft) long. All plants produce spikes of upright, brightly colored flowers well above the foliage, in shades of red, orange and yellow, often bicoloured. The flowers produce copious nectar while blooming and are attractive to bees. In the New World they may attract sap-suckers such as hummingbirds and New World orioles.
The Kniphofia genus is named after Johann Hieronymus Kniphof, an 18th-century German physician and botanist.

sDigitalis Parviflora
Digitalis(/ˌdɪdʒᵻˈteɪlᵻs/or/ˌdɪdʒᵻˈtælᵻs/ is a genus of about 20 species of herbaceous perennials, shrubs, and biennials commonly called foxgloves.
This genus was traditionally placed in the figwort family Scrophulariaceae, but recent phylogenetic research has placed it in the much enlarged family Plantaginaceae. This genus is native to western and southwestern Europe, western and central Asia, Australasia and northwestern Africa. The scientific name means "finger-like" and refers to the ease with which a flower of Digitalis purpurea can be fitted over a human fingertip. The flowers are produced on a tall spike, are tubular, and vary in colour with species, from purple to pink, white, and yellow. The best-known species is the common foxglove, Digitalis purpurea. This biennial plant is often grown as an ornamental plant due to its vivid flowers which range in colour from various purple tints through various shades of light gray, and to purely white. The flowers can also possess various marks and spottings.
The first year of growth of the common foxglove produces only the stem with its long, basal leaves. During the second year of the plant's life, a long, leafy stem from 50 to 255 centimeters tall grows atop the roots of healthy plants.
The larvae of the moth the "foxglove pug" consume the flowers of the common foxglove for food. Other species of Lepidoptera eat the leaves, including the lesser yellow underwing.
The term digitalis is also used for drug preparations that contain cardiac glycosides, particularly one called digoxin, extracted from various plants of this genus.
