Hikers passing through high elevation mountain meadows often catch glimpses of a number of familiar flowers. In fact, many of the mountain meadow natives are closely related to our Kansas native plants.
With nearly daily rain showers, the subalpine grassland meadows of the southern Rocky Mountains are bursting with wildflowers this summer. Rocky Mountain subalpine wildflowers are adapted to high elevations with cooler, shorter summers, longer, colder winters, and intense sunlight. Small, silvery, sun-reflecting, hairy leaves, ground-hugging growth habits, and clumps of showy pollinator-attracting flowers help these Colorado species survive. With a short growing season, flowers are produced and set seed in what seems like record time.
Kansas natives often share similar adaptive features—silvery, fine, hairy, leaves, and similar pollinator-attracting showy flowers –enabling them to survive Kansas’ long, hot summers and cold, dry winters. Although time and physical barriers have separated most Colorado and Kansas native plants into unique species, a few remain as a single species. Let’s take a look at a few of these Colorado cousins.
Columbine (Aquilegia spp)
Kansas’ wild columbine (Aquilegia canadensis) blooms during the cooler, moister spring months of the year, and seed is immediately dispersed. Blue columbine (Aquilegia coerulea) – Colorado’s state flower – blooms in July, taking advantage of the sunshine and warmer days of summer in the high mountains.
Yarrow (Achillea millefolium)
Yarrow (Achillea millefolium) doesn’t change species between Kansas and Colorado, but the blooming time does! While yarrow blooms in late spring in our Kansas prairies, in subalpine mountain meadows, it blooms in July, taking advantage of the sunshine and pollinators of mid-summer. There is little chance that, should they be grown together, cross-pollination could occur between these quite different ecotypes.
Prairie Smoke (Geum triflorum)
Prairie Smoke (Geum triflorum) is another wildflower species that remains the same from Kansas to Colorado. Again, the time of flowering differs. Kansas individuals bloom in spring, and Colorado individuals bloom during similar temperature conditions that occur at the height of the high altitude summer.
Alpine Parsley (Pseudocymopterus spp.)
Members of the carrot and parsley family are commonly found in both Kansas and Colorado. Golden Alexanders (Zizia aurea) grace our gardens in spring, while high mountain meadows are filled with the yellow umbels of mountain parsleys in July.
Primrose (Oenothera spp)
The white, night-blooming showy evening primroses (Oenothera speciosa) typically appear in May and June in Kansas. Come July, their diminutive Colorado cousins, (Oenothera spp) make their appearance in rocky niches and along trails.
Locoweed (Oxytropis spp.)
Locoweed (Oxytropis spp.) fills Colorado mountain meadows with patches of bright pinks, blues and lavenders. Like the wild indigoes (Baptisia spp) that brighten Kansas prairies and pastures, locoweed is a nitrogen-fixing legume. Both are also toxic to cattle, sheep and horses.
Ragwort (Packera spp.)
Ragworts (Packera spp.) are delightful yellow flowers of shade and sun. Colorado’s ragworts are commonly found along a trail’s edge in July. Kansas’ golden ragwort (Packera plattensis) is one of the first wildflowers to brighten winter-weary landscapes in April.
Penstemon (Penstemon spp)
Penstemons (Penstemon spp) are abundant in the Rocky Mountain subalpine meadows in July. Generally short in height and with smaller flowers, they nonetheless add deep, rich lavenders, blues and purples to rocky niches and trailsides. Their taller Kansas cousins precede them, blooming in late spring.
Jacob’s Ladder (Polemonium spp.)
Hike through a subalpine, shaded, moist forest, and suddenly you may encounter a faint scent of skunk, indicating that you have stepped on Jacob’s ladder, a lovely blue-flowered species that hugs the ground with ladder-like leaves. In Kansas, Jacob’s ladder (Polemonium reptans) is a woodland spring ephemera with striking blue, bell-shaped flowers, and yes, the scent of skunk!
Shrubby cinquefoil (Dasiphora (Potentilla) fruticosa)
Shrubby cinquefoil (Dasiphora (Potentilla) fruticosa) is commonly found in high mountain meadows in July. It is just one of a number of cinquefoils that commonly grow at high elevations. Bright yellow flowers attract numerous pollinators. In Kansas, prairie cinquefoil (Dasiphora (Potentilla) arguta), also a shrub, blooms in scattered clumps throughout the summer.
Goldenrod (Solidago spp.)
Our Kansas goldenrods tend to be taller, filling the late summer prairies and pastures with swaths of yellow. They are the harbingers of autumn, blooming in late August and September. Subalpine goldenrods can’t wait that long. The diminutive Rocky Mountain goldenrod begins to flower in mid-July in the high montane meadows, adding their golden color to the seasonal procession of color.
These are just a few of the many familial relationships that exist between Kansas and Rocky Mountain native plants. Next time you travel west, take a moment to find a familiar “face” in the wildflowers at your feet!
