HELLEBORE

Helleborus niger, commonly called Christmas rose or black hellebore, is an evergreen perennial flowering plant in the buttercup family, Ranunculaceae. It is poisonous. Although the flowers resemble wild roses (and despite its common name), Christmas rose does not belong to the rose family (Rosaceae).

The plant is a traditional cottage garden favourite because it flowers in the depths of winter. Large-flowered cultivars are available, as are pink-flowered and double-flowered selections. It has been awarded an Award of Garden Merit (AGM).

It can be difficult to grow well; acid soil is unsuitable, as are poor, dry conditions and full sun. Moist, humus-rich, alkaline soil in dappled shade is preferable. Leaf-mould can be dug in to improve heavy clay or light sandy soils; lime can be added to 'sweeten' acid soils.

CLEMATIS

Clematis is a genus of about 300 species within the buttercup family Ranunculaceae. Their garden hybrids have been popular among gardeners, beginning with Clematis × jackmanii, a garden standby since 1862; more hybrid cultivars are being produced constantly.

They are mainly of Chinese and Japanese origin. Most species are known as clematis in English, while some are also known as traveller's joy, a name invented for the sole British native, C. vitalba, by the herbalist John Gerard; virgin's bower for C. viticella; old man's beard, applied to several with prominent seedheads; and leather flower or vase vine for the North American Clematis viorna.

Illustrated here is the splendid hybrid Clematis 'Daniel Deronda'. Introduced in 1882, 'Daniel Deronda' still holds its own among modern varieties and has given the Royal Horticultural Society's prestigious Award of Garden Merit (AGM) in recognition of its outstanding excellence. It produces purple-blue flowers throughout the summer. These are semi-double early in the season and then single later on. The blooms are followed by eye-catching seed-heads which have a twist at the top.

To prune, remove any dead or weak stems in late winter or early spring and cut remaining stems back to the highest pair of strong-growing buds. To encourage blooms to cover the whole plant, train the stems so that they are evenly spaced on their support. As new growth appears in mid-spring, train this to fill any gaps. Plant in a sheltered position that is not north-facing.

CLEMATIS

Clematis is a genus of about 300 species within the buttercup family Ranunculaceae. Their garden hybrids have been popular among gardeners, beginning with Clematis × jackmanii, a garden standby since 1862; more hybrid cultivars are being produced constantly. They are mainly of Chinese and Japanese origin. They're very popular in gardens with stunning large flowers.

Most species are climbing and look beautiful trained up a trellis. They will grow best with cool moist roots and plenty of sun. They'll grow in most types of fertile soil. They are fairly easy to grow but are susceptible to various diseases and also to pests so they can be a little high maintenance. There are many different colour varieties, from white to lilac, pink and rich burgundy. The flowers are usually large and star shaped. 

This variety, 'Etoile de Paris' was hybridised by Christen in 1885 and has large, showy blue flowers.

DELPHINIUM

Delphinium is a genus of about 300 species of perennial flowering plants in the family Ranunculaceae, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. All members of the Delphinium genus are toxic to humans and livestock. The common name "larkspur" is shared between perennial Delphinium species and annual species of the genus Consolida. The name "delphinium" derives from the Latin for "dolphin", referring to the shape of the nectary.

'Blue Sensation'  hybrid, picture here, is a vigorous Delphinium that will rebloom up to five times after each successive flush when dead headed. Ideal in cottage gardens where it adds a dimension of height and colour. Growing to just under a metre, the strong, well branched stems of Delphinium 'Blue Sensation' are loaded with blooms through summer. Plant in a sunny location with well drained, humus rich soil and fertilise well. Delphinium 'Blue Sensation' can be enjoyed as a cut flower also. Plant Delphinium 'Blue Sensation' in moist, humus rich, well drained soil, that has well-rotted manure or compost worked into the soil prior to planting.

JAPANESE ANEMONES

Anemone hupehensis, Anemone hupehensis var. japonica, and Anemone × hybrida (commonly known as the Chinese anemone or Japanese anemone, thimbleweed, or windflower) are species of flowering herbaceous perennials in the Ranunculaceae family. A. hupehensis is native to central China, though it has been naturalised in Japan for hundreds of years.

The species was first named and described in Flora Japonica (1784), by Carl Thunberg. Thunberg had collected dried specimens while working as a doctor for the Dutch East Indies Company. In 1844, Robert Fortune brought the plant to England from China, where he found it often planted about graves. Height is 1–1.5 m and the leaves have three leaflets. Flowers are 40–60 mm across, with 5-6 (or up to 20 in double forms) sculpted pink or white petals and prominent yellow stamens, blooming from midsummer to autumn.

These plants thrive best in shady areas and under protection of larger plants. They are especially sensitive to drought or overwatering. They can be invasive or weedy in some areas, throwing out suckers from the fibrous rootstock, to rapidly colonise an area. Once established they can be extremely difficult to eradicate. On the other hand, they can take some time to become established.

LOVE-IN-A-MIST

Nigella damascena (love-in-a-mist, ragged lady or devil in the bush) is an annual garden flowering plant, belonging to the buttercup family Ranunculaceae. It is native to southern Europe (but adventive in more northern countries of Europe), north Africa and southwest Asia, where it is found on neglected, damp patches of land. The specific epithet damascena relates to Damascus in Syria.

The plant's common name comes from the flower being nestled in a ring of multifid, lacy bracts. It grows to 20–50 cm tall, with pinnately divided, thread-like, alternate leaves. The flowers, blooming in early summer, are most commonly different shades of blue, but can be white, pink, or pale purple, with 5 to 25 sepals. The actual petals are located at the base of the stamens and are minute and clawed.

The sepals are the only coloured part of the perianth. The four to five carpels of the compound pistil have each an erect style. The fruit is a large and inflated capsule, growing from a compound ovary, and is composed of several united follicles, each containing numerous seeds. This is rather exceptional for a member of the buttercup family. The capsule becomes brown in late summer. The plant self-seeds, growing on the same spot year after year.

BUTTERCUPS

Ranunculus is a large genus of about 600 species of plants in the Ranunculaceae. Members of the genus include the buttercups, spearworts, and water crowfoots. The petals are often highly lustrous, especially in yellow species. Buttercups usually flower in the spring, but flowers may be found throughout the summer, especially where the plants are growing as opportunistic colonisers, as in the case of garden weeds.

Ranunculus repens, the creeping buttercup, is native to Europe, Asia and northwestern Africa. It is also called creeping crowfoot and (along with restharrow) sitfast. It is a herbaceous, stoloniferous perennial plant growing to 50 cm tall. It has both prostrate running stems, which produce roots and new plants at the nodes, and more or less erect flowering stems. The basal leaves are compound, borne on a 4–20 cm long petiole and divided into three broad leaflets 1.5–8 cm long, shallowly to deeply lobed, each of which is stalked.

The leaves higher on the stems are smaller, with narrower leaflets and may be simple and lanceolate. Both the stems and the leaves are finely hairy. The flowers are bright golden yellow, 2–3 cm diameter, usually with five petals, and the flower stem is finely grooved. The fruit is a cluster of achenes 2.5–4 mm long. Creeping buttercup has three-lobed dark green, white-spotted leaves that grow out of the node. It grows in fields and pastures and prefers wet soil.

Like most buttercups, Ranunculs repens is poisonous, although when dried with hay these poisons are lost. The taste of buttercups is acrid, so cattle avoid eating them. The plants then take advantage of the cropped ground around it to spread their stolons. Creeping buttercup also is spread through the transportation of hay. Contact with the sap of the plant can cause skin blistering.

DELPHINIUM

Delphinium ‘Blue Bird’ is a Pacific Giant Delphinium in the family Ranunculaceae suitable for USDA Zones: 2-9. Delphiniums are the stars of the early summer border. Plants form a low mound of deeply-cut green leaves, bearing tall spikes of satiny flowers. This selection has beautiful clear blue petals, with a white centre, or “bee”. Removing faded spikes at the base will encourage repeat blooming in Autumn. In hot, humid summer regions, plants do not usually last more than 2 to 3 years. Plants are often attacked by mildew in mid summer; simply cut back hard to encourage fresh foliage. Use a high phosphorus fertiliser each year, in early spring. Take caution, as this plant is harmful if eaten!

NIGELLA

Nigella is a genus of about 14 species of annual plants in the family Ranunculaceae, native to southern Europe, north Africa, south and southwest Asia. Common names applied to members of this genus are nigella, devil-in-a-bush or love-in-a-mist.

The species grow to 20–90 cm tall, with finely divided leaves; the leaf segments are narrowly linear to threadlike. The flowers are white, yellow, pink, pale blue or pale purple, with five to 10 petals. The fruit is a capsule composed of several united follicles, each containing numerous seeds; in some species (e.g. Nigella damascena), the capsule is large and inflated.

Several species are grown as ornamental plants in gardens. Nigella damascena has been grown in English cottage gardens since Elizabethan times, commonly called love-in-a-mist. Nigella hispanica is a taller species with larger blue flowers, red stamens, and grey leaves. Nigella seeds are self-sowing if the seed pods are left to mature. The dried seed capsules can also be used in flower arrangements.
