Campanula rotundifolia, the harebell, Scottish bluebell, or bluebell of Scotland, is a species of flowering plant in the bellflower family Campanulaceae.

Mertensia is a genus of flowering plants in the family Boraginaceae. They are perennial herbaceous plants with blue or sometimes white flowers that open from pink-tinged buds. Such a change in flower color is common in Boraginaceae and is caused by an increase of pH in the flower tissue. Mertensia is one of several plants that are commonly called "bluebell". In spite of their common name, the flowers are usually salverform (trumpet-shaped) rather than campanulate (bell-shaped).
Mertensia virginica is a spring ephemeral plant in the Boraginaceae (borage) family with bell-shaped sky-blue flowers, native to eastern North America.

It is native to the western United States from eastern California to Wyoming, where it is found in sandy habitat, especially sagebrush. This is a perennial herb growing several erect, slender stems to heights near half a meter from a branching caudex.

It is native to western Canada and the western United States, where it can be found in many types of habitat. A perennial herb growing from a taproot and woody caudex, it is covered with fine, more or less upright, hairs, especially on the stems. It produces a cluster of erect leafy stems ranging from 20 to 50 centimetres centimeters in height. The stems support lance-shaped leaves ranging from 2.5–10 cm (1–4 in) in length. Bunches of flowers with leaf-like bracts appear toward the top of the stem amongst the leaves. The corolla is fused at the base with five lobes which are light yellow, often slightly greenish, and about a centimeter long and wide. The style is short. The fruit consists of one or two, sometimes four, clustered glossy grey nutlets, 3.5 to 6, sometimes as much as 8 mm long.

It is native to the northwestern United States, where it grows in wet mountain habitat. It is a perennial herb producing a slender, erect stem and caudex unit up to half a meter tall. The rough-haired leaves are alternately arranged and borne on petioles. The inflorescence is an open array of clustered bright blue, bell-shaped flowers up to a centimeter wide at the lobed mouths.
Mertensia longiflora is a species of flowering plant in the borage family known by the common names small bluebells and long bluebells.
Streptanthus cordatus is a species of flowering plant in the mustard family known by the common name heartleaf twistflower. It is native to the western United States, where it can be found in many types of sagebrush, woodland, and forest habitat. It is a perennial herb producing a branched or unbranched stem up to about a meter tall. It is often waxy in texture. The basal leaves are oval or spoon-shaped with bristle-toothed blades borne on rough-haired petioles. Leaves higher on the stem are oval to lance-shaped, up to 9 centimeters long with their bases usually clasping the stem. Flowers occur at intervals along the upper stem. Each has a calyx of sepals roughly a centimeter long which begin greenish yellow and mature purple. Four purple petals emerge from the tip of each calyx. The fruit is a thin, narrow silique which may reach 14 centimeters in length or longer.
Toxicoscordion paniculatum is a species of flowering plant known by the common names foothill deathcamas, panicled death-camas, and sand-corn. It is widely distributed across much of the western United States, especially in the mountains and deserts of the Great Basin region west of the Rocky Mountains. It grows in many types of habitat, including sagebrush plateau, grasslands, forests, and woodlands, etc.

Mertensia sibirica, commonly known as Japanese bluebells or Siberian bluebells, is a species of flowering plant belonging to the family Boraginaceae. Originally discovered by Carolus Linnaeus, who named it Pulmonaria sibirica, this plant is found, as its name implies, in Eastern Siberia and northern China. After review of the plant's morphology, its taxonomic position was changed to Mertensia sibirica by botanist and plant collector George Don, who put forth the notion of the change, which was eventually accepted, most likely due to the striking resemblance to the related species in the Americas like Mertensia virginica, or Virginia bluebells.
