Arrowleaf Groundsel Senecio triangularis
Distinctive toothed, triangular-shaped leaves mark this large plant, which can grow to be 20-40 inches (50-100 cm) tall. Several flowerheads cluster atop the single tall stem. The flowers are bright yellow with many petals. Common in the park, generally above 4,000 feet (1,219 meters).
Stem and leaves are hairless, with leaves divided into slender, toothed lobes. Flowers can sometimes be tinged purple, but usually appear yellowish. Growing to a height of 40 inches (100 cm), it is the tallest Lousewort species found in the park.
Broadleaf Arnica Arnica latifolia
A common subalpine species; it can be found growing alone or in clustered groups formed from spreading rootstock. Stems reach about 20 inches (50 cm) in height, with oval, toothed leaves.
Cascade Stonecrop Sedum divergens
Also known as Spreading Stonecrop, this plant grows to form spreading mats. Stems have thick bright green leaves, sometimes tinged with red. Usually found growing on cliff faces and stony slopes.
Dwarf Goldenrod Solidago simplex
Common on talus slopes between 6,000-7,100 feet (1,828-2,164 meters), this alpine plant grows only to four inches (10 cm) tall; a miniature of its cousin, Northern Goldenrod (Solidago multiradiata). It has spoon-shaped to oval leaves diminishing in size along the stem, while the yellow flowers are short and compact.
Fan-leaf Cinquefoil Potentilla flabellifolia
A low, clustered perennial, with basal leaves with three, coarsely toothed leaflets. Common in higher elevation subalpine areas such as the Sunrise area.
Fleabane, Alpine Yellow Erigeron aureus
Also known as Alpine Gold Daisy, this tiny flower is common on the rocky slopes of the mountain between 7,000-8,500 feet (2,133-2,590 meters). It has a compact bunch of basal leaves and a short stem with a single flower, reaching about 6 inches (15 cm) tall. The flower is woolly, with a disk of yellow petals.
Glacier Lily Erythronium grandiflorum
Each plant usually boasts a single flower supported on a 6-12 inch (15-30 cm) long stem (unlike the 2-3 flowers per stem found on Avalanche Lilies), but often found growing in clumps of multiple individuals. Glacier lilies also bloom earlier than Avalanche Lilies or other flowers, sometimes even pushing through late-season snow in order to flower.
Mountain Monkeyflower Mimulus tilingii
Spreads via rootstock and runners to form small patches or mats, with branched stems ranging from 2-8 inches (5-20 cm) long. Commonly found along streams or areas of wet ground.
Rainiera Rainiera stricta
A tall plant, with a leafy stem reaching about 40 inches (100 cm) high. Leaves are hairless and not toothed, diminishing in size as they approach the top of the stem. Flowers form a spike at the top, with each flowerhead containing five yellow flowers. Grows in drier subalpine meadows and open areas, particularly around Sunrise.
Short-beaked Agoseris Agoseris glauca
This stout plant with a dandelion-like flower grows no taller than 6 inches (15cm), with thick, toothless, hairy leaves. Common in drier subalpine meadows above 5,000 feet (1,524 meters), particularly around Sunrise and the north and east sides of the park. Also called Woolly or Pale Agoseris.
