Question: Are at least some of the plants of both Valeriana and Physocarpus native to North America ?

full_context: Document 1: Physocarpus monogynus: Physocarpus monogynus, the mountain ninebark or low ninebark, is a flowering shrub of western North America.
Document 2: Eupatorieae: Eupatorieae is a tribe of over 2000 species of plants in the aster family. Most of the species are native to tropical, subtropical, and warm temperate areas of the Americas, but some are found elsewhere. Well-known members are "Stevia rebaudiana" (used as a sugar substitute), a number of medicinal plants ("Eupatorium"), and a variety of late summer to autumn blooming garden flowers, including "Ageratum" (flossflower) and "Conoclinium" (mistflower).
Document 3: Physocarpus opulifolius: Physocarpus opulifolius, common names common ninebark, Eastern ninebark, ninebark or Atlantic ninebark, is a species of flowering plant in the rose family Rosaceae, native to eastern North America.
Document 4: Exochorda: Exochorda is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan). They are used as ornamental plants with the common name pearl bush, or pearlbush. Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss. As a single species the correct name is "E. racemosa".
Document 5: Vernonia: Vernonia is a genus of about 1000 species of forbs and shrubs in the family Asteraceae. Some species are known as ironweed. Some species are edible and of economic value. They are known for having intense purple flowers. The genus is named for the English botanist William Vernon. There are numerous distinct subgenera and subsections in this genus. This has led some botanists to divide this large genus into several distinct genera. For instance, the "Flora of North America" only recognizes about 20 species in "Vernonia" sensu stricto, 17 of which are in North America north of Mexico, with the others being found in South America.
Document 6: Physocarpus: Physocarpus, commonly called ninebark, is a genus of flowering plants in the family Rosaceae, native to North America (most species) and northeastern Asia (one species).
Document 7: Physocarpus capitatus: Physocarpus capitatus, commonly called Pacific ninebark or tall ninebark, is a species of "Physocarpus" native to western North America from southern Alaska east to Montana and Utah, and south to southern California.
Document 8: Fallopia: Fallopia is a genus of about 12–15 species of flowering plants in the buckwheat family, often included in a wider treatment of the related genus "Polygonum" in the past. The genus is native to temperate and subtropical regions of the Northern Hemisphere. The genus includes herbaceous perennial plants, herbaceous vines, and woody vines.
Document 9: Filipendula: Filipendula is a genus of 12 species of perennial herbaceous flowering plants in the family Rosaceae, native to the temperate regions of the Northern Hemisphere. Well-known species include meadowsweet ("Filipendula ulmaria") and dropwort ("Filipendula vulgaris"), both native to Europe, and queen-of-the-forest ("Filipendula occidentalis") and queen-of-the-prairie ("Filipendula rubra"), native to North America.
Document 10: Physaria: Physaria is a genus of flowering plants in the mustard family. Many species are known generally as twinpods, bladderpods, or lesquerella. They are native to the Americas, with many species endemic to western North America. They are densely hairy annual and perennial herbs often growing prostrate or decumbent, along the ground in patches or clumps. They bear inflorescences of bright yellow flowers. The fruit is often notched deeply, dividing into twin sections, giving the genus its common name.
Document 11: Physocarpus malvaceus: Physocarpus malvaceus is a species of flowering plant in the rose family known by the common name mallow ninebark. It is native to western North America, where its distribution extends from British Columbia to Nevada to Wyoming.
Document 12: Anaphalis: Anaphalis is a genus of herbaceous and woody flowering plants within the Asteraceae family, whose members are commonly known by the name pearl or pearly everlasting. There are around 110 species with the vast majority being native to central and southern Asia. There is one species native to North America that is fairly well known and popular in cultivation, namely the western pearly everlasting ("Anaphalis margaritacea").
Document 13: Valeriana: Valeriana is a genus of flowering plants in the family Caprifoliaceae, members of which may by commonly known as valerians. It contains many species, including the garden valerian, "Valeriana officinalis". Some species are native to Europe, others to North America and South America (especially in the Andes).
Document 14: Valeriana sitchensis: Valeriana sitchensis is a species of valerian known by the common name Sitka valerian. It is native to northwestern North America from Alaska and northern Canada to Montana to northern California, where it grows in many types of habitat, including moist mountain forests. In moist subalpine meadows, it is often one of the most common plants. This is a rhizomatous perennial herb producing a stout, erect stem to about 70 centimeters in maximum height, but known to exceed one meter at times. The leaves vary in size and shape, often having deep lobes or being composed of several leaflets. The inflorescence is a cyme of many white or pink-tinged flowers, each under a centimeter wide. The flower has five corolla lobes and three whiskery stamens protruding from the center.
Document 15: Valeriana edulis: Valeriana edulis (tobacco root, edible valerian), a species in the Caprifoliaceae family, is a dioecious perennial flowering plant native to western and central North America. Despite its common name, tobacco root is not closely related to tobacco, but is instead more closely related to elderberry, honeysuckle, and teasel (Caprifoliaceae s.l.).
