Canna or canna lily is the only genus of flowering plants in the family Cannaceae, consisting of 10 species. All of the genus's species are native to the American tropics and were naturalized in Europe, India and Africa in the 1860s. Although they grow native to the tropics, most cultivars have been developed in temperate climates and are easy to grow in most countries of the world, as long as they receive at least 6–8 hours average sunlight during the summer, and are moved to a warm location for the winter. See the Canna cultivar gallery for photographs of Canna cultivars.
Vegetative reproduction is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
Chromoplasts are plastids, heterogeneous organelles responsible for pigment synthesis and storage in specific photosynthetic eukaryotes. It is thought that like all other plastids including chloroplasts and leucoplasts they are descended from symbiotic prokaryotes.
A leaf spot is a limited, discoloured, diseased area of a leaf that is caused by fungal, bacterial or viral plant diseases, or by injuries from nematodes, insects, environmental factors, toxicity or herbicides. These discoloured spots or lesions often have a centre of necrosis. Symptoms can overlap across causal agents, however differing signs and symptoms of certain pathogens can lead to the diagnosis of the type of leaf spot disease. Prolonged wet and humid conditions promote leaf spot disease and most pathogens are spread by wind, splashing rain or irrigation that carry the disease to other leaves.
Hosta is a genus of plants commonly known as hostas, plantain lilies and occasionally by the Japanese name gibōshi. Hostas are widely cultivated as shade-tolerant foliage plants. The genus is currently placed in the family Asparagaceae, subfamily Agavoideae, and is native to northeast Asia. Like many "lilioid monocots", the genus was once classified in the Liliaceae. The genus was named by Austrian botanist Leopold Trattinnick in 1812, in honor of the Austrian botanist Nicholas Thomas Host. In 1817, the generic name Funkia was used by German botanist Kurt Sprengel in honor of Heinrich Christian Funck, a collector of ferns and alpines; this was later used as a common name and can be found in some older literature.
Hosta 'Undulata' is a cultivar of the genus Hosta, widely cultivated as ornamental plants in borders or as specimen plants. It was formerly regarded as a species under the name Hosta undulata(Otto & A.Dietr.) L.H.Bailey. It is not accepted as a species by the World Checklist of Selected Plant Families as of August 2011, and has been relegated to cultivar status by Schmid.
Fatsia japonica, also fatsi, paperplant, false castor oil plant, or Japanese aralia, is a species of flowering plant in the family Araliaceae, native to southern Japan and southern Korea.
Canna Italian Group 'Trinacria Variegata'. The earliest mention of this cultivar is in 1927, An Amateur in an Indian Garden by S. Percy-Lancaster, F.L.S., F.R.H.S., M.R.A.S., in which it was described and referred to by this name.
The Field Elm cultivar Ulmus minor 'Atinia Variegata', the Variegated-leaved common English Elm, formerly known as U. procera 'Argenteo-Variegata' and described by Weston (1770) as U. campestris argenteo-variegata, is believed to have originated in England in the seventeenth century and to have been cultivated since the eighteenth. The Oxford botanist Robert Plot mentioned in a 1677 Flora a variegated elm in Dorset, where English Elm is the common field elm. Elwes and Henry (1913) had no doubt that the cultivar was of English origin, "as it agrees with the English Elm in all its essential characters". At the Dominion Arboretum, Ottawa, the tree was listed as U. procera 'Marginata', as the variegation is sometimes most obvious on leaf-margins.
The so-called American Elm cultivar Ulmus americana 'Variegata' was a Belgian clone mentioned by Wesmael in Bulletin de la Fédération des sociétés d'horticulture de Belgique, 1862, as Ulmus americana var. variegataHort. It was marketed by the Baudriller nursery of Angers as U. americana foliis variegatis. Wesmael's herbarium specimens, however, held in the Botanic Garden, Meise, both of his Ulmus americana and of his Ulmus americana var. variegata, do not appear to show American white elm leaves. It is known that nurseries in Europe and America marketed the golden wych elm Ulmus glabra 'Lutescens' as Ulmus americana aurea, and it is likely that Wesmael's Ulmus americana variegata was similarly misnamed, and perhaps derived from a reverting branch of aurea, whose leaves it resembled.
The Field Elm cultivar Ulmus minor 'Argenteo-Variegata' or simply 'Variegata', known in Australasia and North America as Silver Elm or Tartan Elm, is said to have been cultivated in France from 1772. Green noted that variegated forms of Field Elm "arise frequently, and several clones may have been known under this name". Dumont de Courset (1802) listed an U. campestris var. glabra variegata, Loudon (1838) an U. nitens var. variegata, and Wesmael (1863) an U. campestris var. nuda microphylla variegata.
Coleus scutellarioides, commonly known as coleus, is a species of flowering plant in the family Lamiaceae, native to southeast Asia through to Australia. Typically growing to 60–75 cm (24–30 in) tall and wide, it is a bushy, woody-based evergreen perennial, widely grown for the highly decorative variegated leaves found in cultivated varieties. Another common name is painted nettle, reflecting its relationship to deadnettles, which are in the same family. The synonyms Coleus blumei, Plectranthus scutellarioides and Solenostemon scutellarioides are also widely used for this species.
Hakonechloa is a genus of bunchgrass in the tribe Molinieae of the grass family, Poaceae, native to eastern Asia.
Strawberry foliar nematode, or strawberry crimp nematode, is a disease caused by Aphelenchoides fragariae, a plant pathogenic nematode. It is common in strawberries and ornamental plants and can greatly affect plant yield and appearance, resulting in a loss of millions of dollars of revenue. Symptoms used to diagnose the disease are angular, water soaked lesions and necrotic blotches. Aphelenchoides fragariae is the nematode pathogen that causes the disease. Its biological cycle includes four life stages, three of which are juvenile. The nematode can undergo multiple life cycles in one growing season when favorable conditions are present. The crowns, runners, foliage, and new buds of the plant via stylet penetration or through the stomata can be infected. The best management practices for this disease are sanitation, prevention of induction of the pathogen to the environment, and planting clean seed or starter plants.
Aucuba japonica, commonly called spotted laurel, Japanese laurel, Japanese aucuba or gold dust plant (U.S.), is a shrub native to rich forest soils of moist valleys, thickets, by streams and near shaded moist rocks in China, Korea, and Japan. This is the species of Aucuba commonly seen in gardens - often in variegated form. The leaves are opposite, broad lanceolate, 5–8 cm (2.0–3.1 in) long and 2–5 cm (0.79–1.97 in) wide. Aucuba japonica are dioecious. The flowers are small, 4–8 mm (0.16–0.31 in) diameter, each with four purplish-brown petals; they are produced in clusters of 10-30 in a loose cyme. The fruit is a red drupe approximately 1 cm (0.39 in) in diameter that is avoided by birds.
Pelargonium capitatum is one of several species known as rose geranium or rose-scented pelargonium in English. The popular names refer to the scent of the essential oils extracted from glandular tissue, not the flowers, which have hardly any scent to speak of. Some of the species are known as kusmalva in Afrikaans.
Acer palmatum, commonly known as Japanese maple, palmate maple, or smooth Japanese maple (Korean: danpungnamu, 단풍나무, Japanese: irohamomiji, イロハモミジ, or momiji,, is a species of woody plant native to Korea, Japan, China, eastern Mongolia, and southeast Russia. Many different cultivars of this maple have been selected and they are grown worldwide for their large variety of attractive forms, leaf shapes, and spectacular colors.
Scindapsus pictus—commonly called satin pothos, silver pothos, or silver vine—is a species of flowering plant in the aroid or arum family, Araceae, native to Bangladesh, Borneo, India, Java, Peninsular Malaysia, the Philippines, Sulawesi, Sumatra, Taiwan and Thailand. The Latin specific epithet pictus means "painted", referring to the variegation on the leaves.
Abutilon mosaic virus (AbMV) is a virus of the genus Begomovirus. It infects Abutilon species, notably the flowering maple, Abutilon striatum. The mottled or variegated effect on the leaves of Abutilon striatum is sought after.
Crassula ovata, commonly known as jade plant, lucky plant, money plant or money tree, is a succulent plant with small pink or white flowers that is native to the KwaZulu-Natal and Eastern Cape provinces of South Africa, and Mozambique; it is common as a houseplant worldwide. Much of its popularity stems from the low levels of care needed; the jade plant requires little water and can survive in most indoor conditions. It is sometimes referred to as the money tree; however, Pachira aquatica also has this nickname.
