Each flower has 5-tiny petals and an interesting fruit that splits in two called a schizocarp. This family used to be called the Umbelliferae because the tiny flower are arranged at the ends of umbrella-like ribs-e.g. 13+ ray flowers per head and ciliate hairs along the petioles of basal leaves.Ĭanada Goldenrod can look a bit like a tall groundsel, but the individual yellow flower heads are tiny. Rocky Mountain or Low Goldenrod – Solidago multiradiata – About 1-1.5’ tall, these tufted plants are often wedged into rocks or along sides of trails. Tall growing species typically have many, mostly same sized, leaves up the stem, and no basal leaves. Low growing species - less than a foot or so –typically have basal clusters of leaves and then small leaves which reduce in size up the stem. Leaves are simple, alternate, smooth edged or slightly toothed. Often these tiny flower heads are arranged along one side of the branching inflorescence. Each of these flower heads has both yellow ray and disc flowers. The flower heads are tiny: 1/8-1/4” wide. These pollinators are attracted to the yellow clusters of flowers. Strong bees and flies are needed to carry pollen, it is so heavy. Their pollen is way too heavy to be tossed on the wind and up your nostrils. Goldenrods – First, goldenrods are not the cause of hay fever. The pollen is too heavy to be carried by wind. The upper leaves may or may not be reduced. Subaplpine Erigeron – Erigeron peregrinus – Flower heads are usually one per stem and the petal-like rays are 2-4 mm wide (relatively broad), usually bluish lavender. Regardless, it is fun to investigate the plants: Can you see similarities and differences between flowers? Pollinators know which is which, if not by name. disc color pappus -bristles or scales seed shape and size are technical aspects that place “asters”, “ daisies”, and “sunflowers” into different genera. However, the variation in “involucral bracts” surrounding the “head” the receptacle shape outer and inner flower types-ray vs. The basic plan of several tiny flowers sitting on a receptacle making each cluster or “head” look like a single flower is universal. The Aster Family is one of the largest plant families in the world. So each flower head can have many, many flowers, hence the old family name Compositae Note the fuzzy bracts surrounding the whole. ![]() This flower head of balsamroot shows the ray flowers on the outside and smaller upright disc flowers clustered on the inside–each will produce a fruit. Harebell – Campanula rotundifolia – The dangling blue bells are long-time favorites of locals, blooming from mid summer to the end of autumn. Long-tongued bees are more likely pollinators. Not to be confused with the lemon-yellow to bluish color Yellow Columbine ( Aquilegia flavescens) which flexes shorter, stubbier spurs. ochroleuca– The delicate “talons” or spur-like petals extend 2” beyond the rounded sepals (which look like petals) and contain nectar for long-tongued pollinators: hummingbirds and hawkmoths. Also reference past “what’s in bloom” pages:Ĭolorado or White Columbine – Aquilegia coerulea var. Keep scrolling down to discover what is in bloom now and to identify what you may have already found. This list does not include the incredible alpine and subalpine flowers found at 9,500’ and above. You may want to visit Goodwin Lake, Two Ocean Lake, and other mid elevations at the north end of the valley as well. Moose-Wilson Road and hikes to Phelps Lake are also great right now. Trails south from Teton Pass and north to Ski Lake exhibit extraordinary diversity of bloom. Mid-elevation hikes are good for botanizing. On any given slope, flowers will mix in different combinations of pink sticky geranium, red to yellow paintbrushes, blue lupines and asters, lavender erigerons, yellow sunflowers, white columbines, to name a very few! On dry slopes, late summer bloomers may be out already, such as Engelmann Aster ( Eucephalus engelmannii). What we think of as spring flowers: Spring beauties ( Claytonia lanceolata) may be blooming in recently melted snow patches. Walk through the meadows up to Ski Lake, and beyond to find flowers.Ĭool canyons and high meadow slopes feature floral bouquets.
