Gutierrezia sarothrae (Broom Snakeweed) – This 1-3 ft. tall sub-shrub has many slender, branching stems and fine yellow-green foliage. Tiny yellow flowers appear in tufts at ends of branches August-November. Flower stems are the same length, producing a yellow-domed, fan-shaped plant when in flower. Needs full sun with low to moderate water. Adapted to dry, open calcareous plains and disturbed areas.
Hedysarum boreale (Northern Sweetvetch) — A member of the Pea family. Plants have many branches with pinnately compound leaves and compact
to elongated clusters of pinkish-purple to reddish-pink pea-like flowers. Blooms April to August and grows 18-24 inches tall. Likes full sun and sandy to rocky soils. Drought tolerant. Attracts butterflies.

Hymenoxys acaulis (Sundancer Daisy) — Like gold coins, the flowers of the Sundancer daisy wave cheerfully in the summer breeze, held above a low-growing cluster of leaves by long (14″), leafless stems. This creates the illusion that the flowers are suspended in mid-air, without any stems at all. It does well in harsh conditions, keeping the leaf profile low, but putting on a good show of flowers to feed native pollinators. Unlike Shasta Daisy, Sundancer keeps its petite size and dainty growth habit without spreading. This Native needs 10-15” water annually enjoying dry soil growing 1-2’ height and 8” width.
Lilium columbianum (Columbia Tiger Lily) – The slender stems of this lily may reach 5-6 ft. and under favorable conditions feature a dozen or more nodding, light-orange flowers, spotted with maroon. Blooms May-September,
depending on elevation. Requires partial shade and well-drained soil that dries out in summer. Adapted to prairies, woodlands and coniferous forests.
Linum perenne v. lewisii (Blue flax) — This 12-24” tall plant produces blue flowers from spring to summer. Each 5-petaled flower lasts just 1 day.

It produces a lot of seed and can spread if the site is well watered.
Lomatium dissectum (Fernleaf Biscuitroot) – This member of the carrot family features finely dissected leaves and small brownish-purple or yellow compound flower umbels at the end of 1-5 ft. stems between April-July. Needs sun to partial shade and low water. Adapted to deep soils in shrub-steppe and mountain meadow habitats. (All plants in this genus contain toxins and should not be ingested.)
Lomatium triternatum (Nineleaf Biscuitroot) – This member of the carrot family features long, narrow, slightly dissected leaves and small yellow flower umbels at the end of 7-30 in. stems between March-July. Needs sun to partial shade and low to moderate water. Adapted to dry or somewhat moist open areas at low to mid-elevations. (All plants in this genus contain toxins
and should not be ingested.)
Lupinus polyphyllus (Bigleaf lupine) — Plants grow up to 30″ tall and are generally associated with moist areas in the mountains. Summer flowers vary from lavender to blue to pink.
Mimulus lewisii (Lewis monkeyflower) — This moisture-loving plant grows along mountain streams and springs. It grows to about 18” tall in full to partial sun. First discovered by Meriwether Lewis, this stunning plant has large, purplish-red tubular flowers.
Penstemon cyaneus (Blue penstemon) — Large, deep purple tubular flowers grace this native perennial that grows to 2 feet tall. Blooms in May and June when planted in full sun. Drought tolerant.
Penstemon deustus (Hotrock penstemon) — Low-growing perennial forb native to Idaho. Easily grown in full sun, producing lots ofwhitetubular flowers
from May-June. Drought tolerant. Often self seeds. Avoid overwatering.
Penstemon eatonii (Firecracker penstemon) — Perennial forb of the Great Basin (UT, NV; not native to Idaho). Easily grown in full sun, produces many red, tubular flowers from May to June. An excellent hummingbird attractant. Drought tolerant. Avoid overwatering. Relatively long-lived.
Penstemon fruticosus (Shrubby penstemon) — A low-growing (to 18” tall), semi-evergreen subshrub with large, blue to lavender tubular flowers in June and July. Requires well-drained soils and is longer lived than many other Penstemons.
Penstemon palmeri (Palmer penstemon) — Short-lived perennial forb of the Great Basin (Utah, Nevada – not native to Idaho). Easily grown in full sun, producing lots of large pink, tubular flowers from May-June. Drought tolerant. Often self seeds. Avoid overwatering.
Penstemon payettensis (Payette penstemon) — Native to west-central Idaho, Payette penstemon produces light to medium blue flowers in late Mate and June. It is moderately drought tolerant and requires full sun and good drainage.
Penstemon rydbergii (Rydberg’s Penstemon) – This small sub-shrub features pale purple to dark blue-violet flowers in dense whorls at the top or along erect stems reaching 7-24 in tall. Flowers appear May-July. Needs full to partial sun and low to moderate water. Adapted to open meadows and drier sagebrush-covered slopes in the foothills and lower elevation mountains.
Penstemon venustus (Lovely penstemon) — Numerous bluish to purple tubular flowers are produced by this 2-3 foot tall plant in May and June. Also a good species for hummingbirds. An Idaho native, this spectacular penstemon requires more moisture than firecracker, hotrock, or Palmer penstemon.
