I'm a paragraph.
Several 1-3 ft. stems emerge in a clump from the woody root of tall fringe bluebells or mountain bluebells.
Smooth, succulent leaves are crowded along these stems. A plant with clumps of leafy stems
loose clusters of narrowly bell-shaped, blue flowers turning pink with age. Pendent clusters of clear blue, tubular flowers exude a mild fragrance.
Root crowns and rhizomes spread over time, forming extensive patches.
annual or biennial grows 6-16 in. high.
Several unbranched stems form clumps topped by bright-red, paintbrush-like spikes.
The flowers are actually inconspicuous and greenish, but are subtended by showy, red-tipped bracts. They sometimes produce a light yellow or pure white variation mixed in with the reds.
Together, the flowers and bracts form 3-8 in. spikes.
The roots of this plant will grow until they touch the roots of other plants, frequently grasses, penetrating these host roots to obtain a portion of their nutrients.
Habitat
Silvery lupine is found in grasslands, ponderosa pine woodlands, on rocky prairie hillsides and on subalpine ridges.
Blue, 3/4" pea-flowers, whorled in conical clusters.
Silvery-hairy leaves, stems, sepals, and seedpods.
Stems are often purplish-red.
Compound leaves

Wild Flowers of Yellowstone
The plants that cover the prairies and forest floors in Yellowstone are a mixed array of shape, size, and color.
Habitat
Mountains, shrub & brushlands
perennials which bear biennial stems from a perennial root system, its full height of 1.5-2.5 m,
large pinnately compound leaves with five or seven leaflets
t produces several side shoots, which bear smaller leaves with three or five leaflets.
The flowers are produced in late spring on short racemes on the tips of these side shoots, each flower about 1 cm diameter with five white petals.
The fruit is red, edible, and sweet but tart-flavoured, produced in summer or early autumn.
A 2-5 ft. widely branching, bushy, perennial
opposite, oval leaves
small groups of tiny, pink, bell-shaped flowers near the branch tips. The flowers’ fragrance is reminiscent of lilac. Numerous small pink, nodding, bell-like flowers, fragrant and striped inside with deeper pink.
Milky juice exudes from broken stems and leaves.
