Primula sect. Dodecatheon is a section of herbaceous flowering plants in the family Primulaceae. [1] [2] [3] [4] Primula species in this section were formerly placed in a separate genus, Dodecatheon. [2] The species have basal clumps of leaves and nodding flowers that are produced at the top of tall stems rising from where the leaves join the crown. The genus is largely confined to North America and part of northeastern Siberia. Common names include shooting star, [5] American cowslip, mosquito bills, mad violets, [6] and sailor caps. A few species are grown in gardens for their showy and unique flower display.
The stamens are thrust out with the sepals bent back. The flowers are pollinated by bees, which grab hold of the petals, and gather pollen by vibrating the flowers by buzzing their wings (buzz pollination). The vibration releases pollen from the anthers.
Carl Linnaeus created the genus Dodecatheon in Species Plantarum in 1753. [7] Dodecatheon could be distinguished by its buzz-pollinated flowers, with reflexed petals and projecting styles and anthers. Repeated molecular phylogenetic studies agreed with morphological and cytological evidence that Dodecatheon was most closely related to one of the subgenera of Primula, P. subgen. Auriculastrum, so that if Dodecatheon is kept separate from Primula, then Primula is not monophyletic. Accordingly, in 2007, Austin R. Mast and James L. Reveal reduced the genus Dodecatheon to Primula sect. Dodecatheon of P. subgen. Auriculastrum, and provided names in Primula for all former Dodecatheon species. [8]
17 Primula species are placed in Primula section Dodecatheon. [8]

Species of Primula sect. Dodecathon need good drainage and often dry soils in summer and winter when plants are dormant, in the spring plants like moist soils for best growth. Plants grown in dry soils tend to be smaller and lower growing. Since plants typically go summer dormant, seed raised plants need three or more years of growth before they are large enough to bloom. For some species, if given frequent light fertilization and kept moist, dormancy can be delayed resulting in larger plants after germination and the interval between germination and flowering decreased by a year or two. Another technique to shorten the interval between seed germination and flowering is to place the plants in a cooler after dormancy has set in, in late spring, and after a number of weeks move the plants to a shadehouse in midsummer where new growth will start. The flowers produce seeds via buzz pollination. [9]
They can be propagated by division in winter.
Several varieties of the Pacific Northwest are edible. [10]
Canna or canna lily is the only genus of flowering plants in the family Cannaceae, consisting of 10 species. Cannas are not true lilies, but have been assigned by the APG II system of 2003 to the order Zingiberales in the monocot clade Commelinids, together with their closest relatives, the gingers, spiral gingers, bananas, arrowroots, heliconias, and birds of paradise.
Phalaenopsis, also known as moth orchids, is a genus of about seventy species of plants in the family Orchidaceae. Orchids in this genus are monopodial epiphytes or lithophytes with long, coarse roots, short, leafy stems and long-lasting, flat flowers arranged in a flowering stem that often branches near the end. Orchids in this genus are native to India, Taiwan, China, Southeast Asia, New Guinea and Australia with the majority in Indonesia and the Philippines.
Primula hendersonii is a species of flowering plant in the family Primulaceae, native to western North America, from California north to southern British Columbia and Idaho. Common names include broad-leaved shooting star, Henderson's shooting star, mosquito bills, and sailor caps.
Buzz pollination or sonication is a technique used by some bees, such as solitary bees to release pollen which is more or less firmly held by the anthers. The anthers of buzz-pollinated plant species are typically tubular, with an opening at only one end, and the pollen inside is smooth-grained and firmly attached. With self-fertile plants such as tomatoes, wind may be sufficient to shake loose the pollen through pores in the anther and accomplish pollination. Visits by bees may also shake loose some pollen, but more efficient pollination of those plants is accomplished by a few insect species who specialize in sonication or buzz pollination.
Primula vulgaris, the common primrose, is a species of flowering plant in the family Primulaceae, native to western and southern Europe, northwest Africa, and parts of southwest Asia. The common name is primrose, or occasionally common primrose or English primrose to distinguish it from other Primula species also called primroses. None of these are closely related to the evening primroses.
Paeonia brownii is a low to medium height, herbaceous perennial flowering plant in the family Paeoniaceae. It has compound, steely-gray, somewhat fleshy leaves and small drooping maroon flowers. Its vernacular name is Brown's peony, native peony or western peony. It is native to the western United States and usually grows at altitude, often as undergrowth in part-shade. The fleshy roots store food to carry the plant through the dry summers and produce new leaves and flowers the following spring.
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants. Flowers produce gametophytes, which in flowering plants consist of a few haploid cells which produce gametes. The "male" gametophyte, which produces non-motile sperm, is enclosed within pollen grains; the "female" gametophyte is contained within the ovule. When pollen from the anther of a flower is deposited on the stigma, this is called pollination. Some flowers may self-pollinate, producing seed using pollen from the same flower or a different flower of the same plant, but others have mechanisms to prevent self-pollination and rely on cross-pollination, when pollen is transferred from the anther of one flower to the stigma of another flower on a different individual of the same species.
Primula scotica, commonly known as Scottish primrose, is a species of flowering plant in the family, Primulaceae, the primroses and their relatives. It was first described by James Smith, and is endemic to the north coast of Scotland.
The Proteaceae form a family of flowering plants predominantly distributed in the Southern Hemisphere. The family comprises 83 genera with about 1,660 known species. Australia and South Africa have the greatest concentrations of diversity. Together with the Platanaceae and Nelumbonaceae, they make up the order Proteales. Well-known genera include Protea, Banksia, Embothrium, Grevillea, Hakea and Macadamia. Species such as the New South Wales waratah, king protea, and various species of Banksia, Grevillea, and Leucadendron are popular cut flowers. The nuts of Macadamia integrifolia are widely grown commercially and consumed, as are those of Gevuina avellana on a smaller scale.
Draba verna, common whitlowgrass, is a species of plant in the cabbage family. It is a small spring-flowering annual which is widely dispersed around the world, and which is found on walls, pavements and patches of bare ground. It has a complex taxonomy which is not yet fully elucidated.
Primula meadia, the shooting star or eastern shooting star, is a species of flowering plant in the primrose family Primulaceae. It is native to the eastern United States and Canada, spanning north from Manitoba and New York, south to Texas and Florida.
Primula pauciflora, the pretty shooting star, few-flowered shooting star, dark throat shooting star or prairie shooting star, is a species of flowering plant in the primula family Primulaceae. It is a widespread and very variable species, native to western North America, from Subarctic America to Mexico, often in xeric and desert habitats. It is found in the Great Basin Deserts and Mojave Desert. Its synonyms include Dodecatheon pauciflorum and Dodecatheon pulchellum.
