Eriogonum arborescens

Eriogonums belong to the family Polygonaceae, and they are commonly known as "wild buckwheat". California has many species, including Eriogonum arborescens, from the Channel Islands off the coast of Southern California. Many species in the genus are more herbaceous than woody, but this one is a bush up to 5 feet tall (1.5 m). It looks like a miniature tree, as is implied by its name "arborescens". It produces many clusters of tiny flowers over a long period in the summer and fall, and these are initially pale pink. Later in the season, the brown-tinged old flowers combine with the pink new ones to give a salmon-tinged effect, as seen in the photo. A great species for a dry-summer landscape!

#2195 - Rumex obtusifolius - Broad-leaved Dock

AKA bitter dock, , bluntleaf dock, dock leaf, dockens or butter dock. Named Rumex obtusifolius by Carl Linnaeus, and surprsingly has kept it, compared to some of the taxonomic nightmares I've described before. Rumex was Pliny's name for sorrel, while obtusifolius means 'obtuse-leaved'.

A highly invasive weed found on all temperate continents. In its native range in Europe the young leaves have been used in salads, or as a substitute in stuffed graped leaves, or squeezed to treat nettle stings. The seeds can be ground into flour and the roots was boiled to treat boils.

Pau-formiga – Triplaris americana

Nome Científico:Triplaris americana Nomes Populares: Pau-formiga, Formigueiro, Novateiro, Pajeú, Paliteiro, Pau-de-formiga, Pau-de-novato, Pau-de-tachi, Tachi, Tangarana, Taquari Família: Polygonaceae Categoria: Árvores, Árvores Ornamentais Clima: Equatorial, Subtropical, Tropical Origem: América do Sul, Brasil, Paraguai Altura: acima de 12 metros Luminosidade: Sol Pleno Ciclo de Vida: Perene

Sobre a Pau-formiga ou Pau-de-novato

Devido à sua copa colunar e beleza no florescimento e frutificação, é amplamente usada no paisagismo, sendo útil para arborização de ruas estreitas desprovidas de rede eléctrica. A Pau-formiga é muito útil também para recuperação de florestas ciliares. O nome popular desta espécie (Pau-formiga) é proveniente de sua associação com formigas no ambiente natural, que constroem seus ninhos no tronco oco, protegendo assim as plantas de outros predadores.

Pau-formiga atinge tamanho padrão de comercialização em menos de 2 anos. Pau-formiga deve ser cultivado sob sol pleno, em solo fértil, profundo, húmido, enriquecido com matéria orgânica e irrigado regularmente. A floração ocorre no inverno e início da primavera e é bastante durável. De tronco oco e abrigo para formigas (daí a razão do nome comum), o pau-formiga pode chegar a 20 metros de altura. As podas são desaconselhadas por descaracterizarem a copa. Transplantar quando atingir 10 cm de altura para sacos de cultivo com substrato semelhante ao do plantio da muda, deixando em cultivo protegido, realizando regas periódicas. Uso medicinal: A casca é utilizada contra disenteria. Outros usos: A espécie é ornamental devido a sua bela floração e formato da copa, sendo empregada no paisagismo. A casca contém tanino que pode ser aplicado em diferentes usos. Mais info: https://pt.wikipedia.org/wiki/Triplaris_americana Read the full article

Eriogonum crocatum

California is home to many species of Eriogonum, plant in the Polygonaceae commonly known as buckwheats or wild buckwheats. These range from tiny ground-hugging alpine species to substantial shrubs, but in all cases they have clusters of tiny flowers. The plant pictured is Eriogonum crocatum, known as the saffron buckwheat. It features a striking combination of felted white leaves and greenish-yellow flowers, and it is native to Ventura County and western Los Angeles County in southern California.
