Orange honeysuckle or western trumpet honeysuckle is collected near Kamiah in Idaho, on June 5th 1806 by Meriwether Lewis on the banks of the Clearwater river, during the Lewis and Clark expedition from St. Louis to the west coast (1805 – 1807). It was introduced in England in 1824.
It prefers a well-drained, but still moist soil, especially if it has lots of organic debris. Need a plenty sunlight to make it flower freely, but also succeeds in partial shade, but it loves its roots in the shade.
