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

Context paragraphs:
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).

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).

Invasive grasses of North America: Grasses are one of the most abundant floras on all continents except Antarctica.  Their divergence is estimated to have taken place 200 million years ago.  Humans have intentionally and unintentionally introduced these species to North America through travel and trade.  On the North American plains, prairies, grasslands, and meadows at least 11% of grasses are non-native.  North America is considered a hotspot for many of grasses, which threatens all of the endangered native grass species and potentially threatens other grass species.  Conservation tactics and management policies can help prevent invasive species from taking over and driving native North American plants to extinction.

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.

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.

Emerald ash borer: Agrilus planipennis, commonly known as the emerald ash borer, is a green buprestid or jewel beetle native to northeastern Asia that feeds on ash species.  Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years.  In its native range, it is typically found at low densities and does not cause significant damage to trees native to the area.  Outside its native range, it is an invasive species and is highly destructive to ash trees native to northwest Europe and North America.  Prior to being found in North America, very little was known about emerald ash borer in its native range; this has resulted in much of the research on its biology being focused in North America.  Local governments in North America are attempting to control it by monitoring its spread, diversifying tree species, insecticides, and biological control.

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.

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.).

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.

Physocarpus monogynus: Physocarpus monogynus, the mountain ninebark or low ninebark, is a flowering shrub of western North America.
