Darmera
''Darmera peltata'', the Indian rhubarb or umbrella plant, is a flowering plant, the only species within the genus ''Darmera'' in the family Saxifragaceae.Sierra Nevada Wildflowers, Karen Wiese, 2nd ed, 2013, p 90 It is a slowly spreading rhizomatous perennial native to mountain streamsides in woodland in the western United States (western Oregon to northwestern California), growing to tall by wide. The name ''Darmera'' honors Karl Darmer, a 19th-century German horticulturist. In late spring the flowers emerge before the leaves, with rounded cymes of numerous five-petalled white to bright pink flowers (measuring up to 1.5 cm across each) borne on flower stems up to 2m long. The leaves, up to long and wide, are peltate, rounded, deeply lobed, coarsely toothed, conspicuously veined and dark green, also on stems petioles up to height. The leaves turn red in autumn. In gardens, ''Darmera peltata'' flourishes in pond margins and bog gardens, where it forms an imposing umbr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxifragaceae
Saxifragaceae is a family of Herbaceous plant, herbaceous Perennial plant, perennial flowering plants, within the core eudicot Order (biology), order Saxifragales. The Taxonomy (biology), taxonomy of the family has been greatly revised and the scope much reduced in the era of Molecular phylogenetics, molecular phylogenetic analysis. The family is divided into ten clades, with about 640 known species in about 35 accepted genera. About half of these consist of a single species, but about 400 of the species are in the type genus ''Saxifraga''. The family is predominantly distributed in the northern hemisphere, but also in the Andes in South America. Description Species are Herbaceous plant, herbaceous Perennial plant, perennials (rarely Annual plant, annual or biennial plant, biennial), sometimes Succulent plant, succulent or Xerophyte, xerophytic, often with perennating rhizomes. The Leaf, leaves are usually basally aggregated in alternate rosettes, sometimes on inflorescence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cyme (botany)
In botany, an inflorescence is a group or cluster of flowers arranged on a plant's stem that is composed of a main branch or a system of branches. An inflorescence is categorized on the basis of the arrangement of flowers on a main axis ( peduncle) and by the timing of its flowering (determinate and indeterminate). Morphologically, an inflorescence is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. General characteristics Inflorescences are described by many different characteristics including how the flowers are arranged on the peduncle, the blooming order of the flowe ...

Flora Of California
California native plants are plants that existed in California prior to the arrival of European colonialism, European explorers and colonists in the late 18th century. California includes parts of at least three Phytochorion, phytochoria. The largest is the California Floristic Province, a geographical area that covers most of California, portions of neighboring Oregon, Nevada, and Baja California, and is regarded as a "world hotspot" of biodiversity. Introduction In 1993, ''The Jepson Manual'' estimated that California was home to 4,693 native species and 1,169 native subspecies or varieties, including 1,416 endemic species. A 2001 study by the California Native Plant Society estimated 6,300 native plants. These estimates continue to change over time. Of California's total plant population, 2,153 species, subspecies, and varieties are endemism, endemic and native to California alone, according to the 1993 Jepson Manual study. This botanical diversity stems not only from the si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Saxifragaceae Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical system. ...

Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. It includes the full range of cultivated plants, from annuals, biennials and perennials to shrubs and trees. It covers plants grown for specific purposes - such as vegetable crops, fruit, hedging, topiary, groundcover, summer bedding, houseplants, etc. It tests characteristics such as robustness, hardiness, longevity, flowering/fruiting abundance and quality, usefulness, and ease of cultivation. It pays particular attention to a plant's ability to survive and thrive in challenging conditions such as wind and frost. The AGM trophy symbol is widely used in gardening literature as a sign of exceptional quality, and is recognised as such by writers, horticulturalists, nurseries, and everybody in the UK who practises gardening.

Royal Horticultural Society
The Royal Horticultural Society (RHS), founded in 1804 as the Horticultural Society of London, is the UK's leading gardening charity. The RHS promotes horticulture through its five gardens at Wisley (Surrey), Hyde Hall (Essex), Harlow Carr (North Yorkshire), Rosemoor (Devon) and Bridgewater (Greater Manchester); flower shows including the Chelsea Flower Show, Hampton Court Palace Flower Show, Tatton Park Flower Show and Cardiff Flower Show; community gardening schemes; Britain in Bloom and a vast educational programme. It also supports training for professional and amateur gardeners. the president was Keith Weed and the director general was Clare Matterson CBE. History Founders The creation of a British horticultural society was suggested by John Wedgwood (son of Josiah Wedgwood) in 1800. His aims were fairly modest: he wanted to hold regular meetings, allowing the society's members the opportunity to present papers on their horticultural activities and discov ...

Gunnera Tinctoria
''Gunnera tinctoria'', known as giant rhubarb, Chilean rhubarb, or ''nalca'', is a flowering plant species native to southern Chile and neighboring zones in Argentina. It is unrelated to rhubarb, as the two plants belong to different order (biology), orders, but looks similar from a distance and has similar culinary uses. It is a large-leaved perennial plant that grows to more than two metres tall. It has been introduced to many parts of the world as an ornamental plant. In some countries, such as New Zealand, the United Kingdom and Ireland, it has spread from gardens and is becoming an introduced species of concern. It is known under the Synonym (taxonomy), synonyms: ''Gunnera chilensis'' Jean-Baptiste Lamarck, Lam. and ''Gunnera scabra'' Hipólito Ruiz López, Ruiz & Pav. Taxonomy It was first described in 1782 by Juan Ignacio Molina as ''Panke tinctoria'', and was transferred to the genus ''Gunnera'' in 1805 by Charles-François Brisseau de Mirbel.

Bog Garden
A bog garden is a type of garden that employs permanently moist (but not waterlogged) soil to create a habitat for plants and creatures which thrive in such conditions. It may exploit existing poor drainage in the garden, or it may be artificially created using pond liners or other materials to trap water in the area. Any such structure must allow a small amount of seepage to prevent the water stagnating. For instance, a pond liner must be pierced a few times. Typically a bog garden consists of a shallow area adjoining a pond or other water feature, but care must be taken to prevent water draining from a higher to a lower level. The minimum sustainable depth is . Good drainage is provided by gravel placed over the liner, and the bog can be kept watered by using a perforated hose below the surface. Plants which enjoy boggy soil or shallow water around their roots (marginals) include: * '' Butomus umbellatus'' (flowering rush) * '' Caltha palustris'' (marsh marigold) * '' Diona ...
