Dianthus Plant

  • Dianthus is a genus of about 300 species of flowering plants in the family Caryophyllaceae, native mainly to Europe and Asia, with a few species extending south to north Africa, and one species in arctic North America. Wikipedia
  • Scientific name: Dianthus
  • Rank: Genus
  • There are numerous types of dianthus, so there’s one for almost any garden situation. Many types have flowers with a fragrant, spicy scent and notched petals. Common dianthus include Sweet William, pinks, and carnations.

    About This Plant

    Most dianthus have pink, red, or white flowers with notched petals. Sweet Williams are biennial or short-lived perennials covered with bicolor flowers in late spring. Pinks are low-growing dianthus suitable for rock gardens. Carnations are taller and good for bouquets but tend to be less hardy than other dianthus.

    Special Features

    • Multiplies readily
    • Fragrant
    • Good for cut flowers -Carnations for cut flowers
    • Deer resistant

    Site Selection

    • Select a site with full sun and well-drained soil, preferably with neutral to alkaline soil pH. Dianthus won’t tolerate wet soils, especially in winter.

    Planting Instructions

    • Plant in spring or fall, spacing plants 6 to 12 inches apart, depending on the type. Prepare the garden bed by using a garden fork or tiller to loosen soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost. Dig a hole twice the diameter of the plant’s container. Carefully remove the plant from its pot and place it in the hole so the top of the root ball is level with the soil surface. Carefully fill in around the root ball and firm the soil gently. Water thoroughly.

    Care

    • Apply a thin layer of compost each spring, followed by a 2-inch layer of mulch to retain moisture and control weeds. Water plants during the summer if rainfall is less than 1 inch per week. Stake tall varieties to keep them upright. Remove spent blooms on tall varieties, or shear back mounding plants after bloom to encourage rebloom. After the first killing frost, cut stems back to an inch or two above soil line. Divide plants every 3 to 4 years as new growth begins in the spring, lifting plants and dividing them into clumps.

Dianthus barbatus (Sweet William- above) is a species of Dianthus native to southern Europe and parts of Asia which has become a popular ornamental garden plant. It is a herbaceous biennial or short-lived perennial plant growing to 30–75 cm tall, with flowers in a dense cluster of up to 30 at the top of the stems. Each flower is 2–3 cm diameter with five petals displaying serrated edges. Wild plants produce red flowers with a white base, but colours in cultivars range from white, pink, red, and purple or with variegated patterns. The exact origin of its English common name is unknown, but first appears in 1596 in botanist John Gerard‘s garden catalog.

 

The flowers are edible and may have medicinal properties.  Sweet William attracts bees, birds, and butterflies.

Description

Sweet william is a herb biennial or short-lived perennial plant native to the mountains of southern Europe from the Pyrenees east to the Carpathians and the Balkans, with a variety disjunct in northeastern China, Korea, and southeasternmost Russia.It grows to 30–75 cm tall, with green to glaucous blue-green tapered leaves 4–10 cm long and 1–2 cm broad. The flowers are produced in a dense cluster of up to 30 at the top of the stems and have a spicy, clove-like scent; each flower is 2–3 cm diameter with five petals with serrated edges; in wild plants the petals are red with a white base.

There are two varieties:

  • Dianthus barbatus var. barbatus. Southern Europe. Leaves broader, up to 2 cm broad.
  • Dianthus barbatus var. asiaticus Nakai. Northeastern Asia. Leaves slenderer, not over 1 cm broad.

English name

Many legends purport to explain how sweet William acquired its English common name, but none is verified. “Sweet William” is often said to honour the 18th century Prince William, Duke of Cumberland. As a result of the Duke’s victory at the Battle of Culloden and his generally brutal treatment of the king’s enemies, it is also claimed that the Scots sometimes call the flower “Stinking Billy”.] Though this makes a nice story, it is entirely untrue. The Scots sometimes refer to the noxious ragwort, not Dianthus barbatus, as “Stinking Billy” in memory of the infamous Duke. Also, the English botanist John Gerard referred to Dianthus barbatus as “Sweete Williams” in his garden catalogue of 1596, 150 years before Culloden. Phillips speculated that the flower was named after Gerard’s contemporary, William Shakespeare. It is also said to be named after Saint William of York or after William the Conqueror. Another etymological derivation is that william is a corruption of the French oillet, meaning “little eye”. Sweet william is a favourite name for lovelorn young men in English folkloric ballads, e.g., “Fair Margaret and Sweet William.”

ImageCultivation and uses

  • Sweet william is a popular ornamental plant in gardens, with numerous cultivars and hybrids selected for differing flower colour, ranging from white, pink, red, and purple or with variegated patterns.
  • The plant was introduced to northern Europe in the 16th century, and later to North America and elsewhere, and has become locally to widely naturalised in these areas.
  • John Gerard praises its beauty but omits any reference to medicinal uses. Its height makes it convenient for flower arrangements. In the Victorian language of flowers, sweet william symbolizes gallantry. The plant is widely used in borders, rock gardens and informal country cottage style gardens. Sweet william is a good candidate for a naturalistic garden because its nectar attracts birds, bees, and butterflies. Its flowers are considered edible.
  • It thrives in loamy, slightly alkaline soil with sun to partial shade. Propagation is by seed, cuttings, or division, but seeds of cultivars will not breed true. If it is planted from seed after the last frost, it will flower in the second year. If it is planted in flats before the last frost and then transplanted it may flower in the first year. Some gardeners recommend deadheading to encourage further flowering. The plant is self-seeding. Sweet william can suffer from Fusarium Wilt which causes the leaves to curl or droop down.
  • In 1977 the question of possible medical uses was revisited by Cordell. Saponins were found in sweet william, but there has been little followup.
  • At the wedding of Prince William and Catherine Middleton on 29 April 2011, Catherine Middleton included sweet william in her bouquet, a tribute to her bridegroom.Image

Chinese Pinks, also popularly known as Indian Pinks or Japanese Pinks are a free blooming variety of plants originated in Eastern Asia. The scientific name of these plants is Dianthus chinensis or Dianthus sinensis. The pinks are excellent for beds, borders, edgings, rock gardens, pots and cut flowers.

  • The Dianthus chinensis varieties are specially suitable for borders, Dianthus heddewigii for bedding and edging, Dianthus lacinatus for rockery and bedding and the hardy perennial pinks – Dianthus plumerius, Dianthus allwoodi, Dianthus winteri, etc.) for rock gardens and edging.

Chinese Pinks bear brilliantly colored large delightfully fragrant flowers. The Chinese Pink flowers may be self-coloredexquisitely marked, edged, blotched, spotted, or eyed with contrasting colors. In some, the flowers have finely fringed petals. There are also varieties producing blooms in clusters on upright and strong stems. The name pinks doesn’t imply only pink colored flowers. They come in a wide variety of colors viz., pink, rose, scarlet, red, crimson, and so forth.

The pinks are propagated by seeds. They flourish well in sunny to part shady, moderately dry, well-drained, organic-rich soil. A very ornamental plant, it is usually biennial in habit, but can be a short-lived perennial.

The Chinese pinks have high medicinal value. They have been used for over 2,000 years in Chinese herbal medicine. The whole plant is a bitter tonic herb that stimulates the digestive and urinary systems and also the bowels. It is also anthelmintic, antibacterial, antiphlogistic, diaphoretic, diuretic, emmenagogue, febrifuge and haemostatic. It is used internally in the treatment of acute urinary tract infections (especially cystitis), urinary stones, constipation, failure to menstruate and many other physiological aberrations and dysfunctions.

 

ImageViolets (Viola) are a genus of Spring flowering plants in the family Violaceae. There are around 400-500 species of Violets in the genus. Violets are native to the temperate Northern Hemisphere and are also distributed in Hawaii, Australasia, and the Andes in South America. Violets are found in moist and slightly shaded conditions such as hedgerows.

The word ‘Violet’ comes from the Latin name ‘Viola’. Ordinary Violets, Common Blue Violets, Sweet violets and Garden violets are some of the popular varieties of violets. Most Violets are small perennial plants, but a few are annual plants and some are small shrubs.

Violets typically have heart-shaped leaves, and asymmetrical flowers. The shape of the petals defines many species, for example, some Violets have a spur at the end of each petal. Flower colors vary among the Violets, many of which are violet as their name suggests, and some are blue, yellow, white and cream. Some are bicolored, often blue and yellow.

ImageFacts about Violets

  • True Violets have been known for centuries with the ancient Greeks cultivating them about 500 BC or earlier. Both the Greeks and the Romans used Violets for all sorts of things such as herbal remedies, wine (‘Vinum Violatum’), to sweeten food and for festivals.
  • Strictly, Sweet violets, Bedding Violas and Pansies are all classified as “violas”. Sweet Violets descended from the European wild sweet violet, Viola odorata. Bedding Violas (the flower that we usually call “violas”) were hybridized from pansies and Viola cornuta. Pansies developed from the wild violas, Viola lutea and Viola tricolor (“johnny-jump-up”).
  • Violets are used as food plants by the larvae of some Lepidoptera species.
  • Crossings of a number of plants were developed and these were known as the ‘Quatre saisons’ violets. Along with the so-called ‘Russian Violet’ introduced in the latter part of the 19th century, these horticultural efforts gave us the Violets we grow today.
  • The Blue violet is common to the United States, growing from Maine to Florida.
  • The Ancient Greeks considered the Violet a symbol of fertility and love; they used it in love potions. Pliny recommended that a garland of violets be worn above the head to ward off headaches and dizzy spells.
  • The genus includes the Dog Violets, a group of scentless species which are the commonest violets in many areas; the Sweet Violet, Viola odorata (named from its sweet scent) and many other species whose common name includes the word “Violet”. Several species are known as Pansies.
  • The purple violet/Wood Violet/ blue prairie Violet/Prairie blue Violet/hooded blue Violet/meadow blue Violet/and butterfly Violet, is very popular in the eastern United States and is Wisconsin’s State Flower.
  • Violets should not be taken internally in large doses. Violet flowers are edible, used in medicines, as a laxative, and the flowers are candied for decoration in jellies, etc.

True Violets

Saintpaulia is a genus comprising African violets, which are not true Violets. The main differences between African Violets and True violets are:

  • African violets are mainly grown as houseplants. They are shallow rooting plants that enjoy a good amount of light as long as it is in the shade. True violets are deep-rooting outdoor plants that thrive in partial shade to full sun.
  • African violets have fleshy downy leaves and produce throughout the summer, five-petalled flowers, usually with a distinct eye while true violets have large to small heart shaped leaves, sometimes smooth, sometimes with varying degrees of hairiness. The flowers are produced from September through to March and most, apart from the Parma Violets, which are frost tolerant.

 

Varieties of Violets

  • Viola arvensis – Field Pansy
  • Viola biflora – Yellow Wood Violet or Twoflower Violet
  • Viola canina – Heath Dog Violet
  • Viola hirta – Hairy Violet
  • Viola odorata – Sweet Violet
  • Viola pedunculata – Yellow Pansy
  • Viola riviniana – Common Dog Violet
  • Viola tricolor – Wild Pansy or Heart’s-ease
  • Viola adunca – Early Blue Violet
  • Viola nephrophylla – Northern Bog Violet
  • Viola pedatifida – Crowfoot Violet
  • Viola pubescens – Downy Yellow Violet
  • Viola rugulosa – Western Canada Violet

Growing Violets

Violets are easily cultivated through root cuttings or seeds.

  • Violets are best grown in the dappled shade of deciduous trees thus allowing full winter and spring sunshine.
  • Choose a site with full sun to light shade. Violets also like well-drained, fairly rich soil, so work in a spadeful or two of compost at planting time for best results.
  • Plant Violets in early spring, four to six weeks before your region’s last frost date.
  • Plant 4 to 8 inches apart, depending on the variety.
  • Mulch to keep roots cooler longer.
  • Water only moderately. Although they love cool conditions, Violets don’t need huge amounts of water.
  • Pinch off spent blooms to promote longer flowering.
  • Fertilize once after blooming starts.

ImageViolet Plant Care

Prick out the seedlings into individual pots when they are large enough to handle and plant them out in summer. Violets should receive extra moisture in dry weather, as Red Spider Mite is liable to attack if they are allowed to get parched. Spraying with a hose is helpful. Occasional feeding with soot water or liquid manure and even a top dressing of blood or bone is helpful for good blooms.

Division during the autumn or just after flowering. Larger divisions can be planted out direct into their permanent positions, though it is best to pot up smaller divisions and grow them in light shade in a greenhouse or cold frame until they are growing away well. Keep runners picked off during the growing season. This will encourage good sized flowers.

Botanical name: Petunia

Plant type: Flower

Sun exposure: Full Sun

Flower color: Red, Pink, Yellow, Purple, White

Bloom time: Spring, Summer, Fall

Petunias are one of the most popular type of annual. They are divided into two different groups: Grandiflora petunias have very large flowers and are best grown in containers or hanging baskets (because they are more susceptible to rain damage), and Multiflora petunias have smaller, but more abundant flowers and are ideal for summer bedding or in a mixed border (because they are more tolerant to wet weather).

ImagePlanting

  • You can grow petunias from seeds, but it is easier to grow them from transplants. If you are going to grow from seeds, start them indoors 10 to 12 weeks before you want to set them outside. Petunia seeds are very small and needs lots of light in order to germinate. Remember to water them. When the plants have three leaves, you can plant them outside.
  • It’s best to buy transplants and plant them in light, well-drained soil in full sun after the last spring frost. Petunias can grow in partial shade, but they will have fewer flowers. It’s better if the plants have shelter from the wind.
  • Space the plants about 1 foot apart.
  • If you’re planting petunias in containers, use a soil-less mix.

Care

  • Petunias are tolerant of heat so you don’t have to water them regularly. A thorough watering once a week should be sufficient (unless there are prolonged periods of drought in your area). The spreading types and those in containers require more frequent watering though.
  • Fertilize your plants monthly to ensure good growth. Double-flowered cultivars like a biweekly dose of fertilizer.
  • Remove faded/dead flowers to prolong blooming.

Pests

  • Aphids
  • Caterpillars
  • Leaf miners
  • Gray mold
  • Bacterial soft rot
  • Leaf spots
  • Viruses

Recommended Varieties

  • Carpet Series, which is ideal for a ground cover and offers a wide variety of colors

Fire Orange Rhodendendron

 

Species of the genus Rhododendron are native to every continent of the world, except South America and Africa.[9] The highest species diversity is found in the Himalayas from Uttarakhand, Nepal and Sikkim to Yunnan and Sichuan, with other significant areas of diversity in the mountains of Korea, Japan and Taiwan.

Tropical rhododendron species range from southeast Asia to northern Australia, with 55 known species in Borneo and 164 in New Guinea. Interestingly, the species in New Guinea are native to subalpine moist grasslands at around 3000 metres above sea level in the Central Highlands. ] Relatively fewer species occur in North America and Europe.

Invasive species

Some species (e.g. Rhododendron ponticum in Ireland and the United Kingdom) are invasive as introduced plants, spreading in woodland areas replacing the natural understory. R. ponticum is difficult to eradicate, as its roots can make new shoots.

Insects

A number of insects either target rhododendrons or will opportunistically attack them. Rhododendron borers and various weevils are major pests of rhododendrons, and many caterpillars will preferentially devour them.

Rhododendron species are used as food plants by the larvae of some members of the order Lepidoptera (butterflies and moths) (See List of Lepidoptera that feed on rhododendrons).

Diseases

Major diseases include Phytophthora root rot, stem and twig fungal dieback; Ohio State University Extension provides information on maintaining health of rhododendrons. Rhododendrons can easily be suffocated by other plants.

light pink bough

Rhododendron is a genus characterized by shrubs and small to (rarely) large trees, the smallest species growing to 10–100 cm (3.9–39 in) tall, and the largest, R. giganteum, reported to over 30 m (98 ft) tall.[4] The leaves are spirally arranged; leaf size can range from 1–2 cm (0.39–0.79 in) to over 50 cm (20 in), exceptionally 100 cm (39 in) in R. sinogrande. They may be either evergreen or deciduous. In some species, the undersides of the leaves are covered with scales (lepidote) or hairs (indumentum). Some of the best known species are noted for their many clusters of large flowers. There are alpine species with small flowers and small leaves, and tropical species such as section Vireya that often grow as epiphytes. Species in this genus may be part of the heath complex in oak-heath forests in eastern North America.
