Flowers of Early June

My blog for this week, on petunias (Petunia), is running way behind. So, how about a post celebrating  early summer flowers? 

Blanket flower, Gaillardia (sunflower family, Asteraceae), below, is native to North America. There are 12 species, but only two are widespread, Gaillardia aristida and Gaillardia pulcella. The first is in the western and northern North America, the second in eastern and southern. Gaillardia xgrandiflora is their hybrid. I've seen them growing in gardens from Oregon to Florida, and if you were out hiking now, you could find wild ones in flower, all across the continent.

Ecuador: The Galapagos II. Plants

On my recent trip to the Galapagos I joined park rangers on hikes, and usually I was a laggard. I kept  stopping to see the plants. The rest of the group hopped from one animal photo op to the next. I tried to keep up but did a bad job of it.

Just like its  animals, the Galapagos's plants include many that are unique and that differ from their mainland relatives and between islands.

Ecuador: The Galapagos (I)

I recently visited the Galapagos for the first time, on a tour with the Minnesota Landscape Arboretum and Knowmad Adventures. The Galapagos Islands, whose animals and plants played a crucial role in Charles Darwin formulating his ideas of evolutionary change, is Must See location for biologists...so, contrarily, I scorned it for 50-odd years. But, eventually my curiousity sent me there.

Yellow Sweet Clover, Melilotus officinalis, and White Sweet Clover, Melilotus albus

Sweet clover, genus Melilotus, is a group of some 23 species native to Eurasia, in the pea family, Fabaceae. Two of them, yellow sweet clover, Melilotus officinalis, and white sweet clover, Melilotus albus, are found all over North America. They are weedy and often quite aggressive, building up large populations quickly. But they add nitrogen to the soil, are good forage for livestock, are a source of honey for bees, and more. They have both supporters and detractors.

Tallgrass Prairie in Spring

As winter ends, the tallgrass prairie is a chaotic place, the three-to-five foot grass stalks lying in a tangled mess. All is brown. There is little to see.

Spring Wildflowers in a Minnesota Forest

The deciduous forests of eastern North America seem very dull as winter becomes spring. The snow vanishes to leave a layer of brown leaves under the leafless trees.

Nevertheless, as the temperatures warm, it is irresistable to wander outdoors in the forest.

And, then you spot a spring wildflower!

Parking Lot Edge Wildflowers, Estes Park, Colorado

Particular plant species generally have particular habitats where you will find them. Rainfall, temperature range, shade, soil characteristics and disturbance (level of trampling or grazing or similar effects) determining where a plant thrives and where it does not survive. Thus, if you go looking for flowers, which ones you find depends on where you walk. 

We tend to see the same ones over and over, because they grow well where people walk, liking the sunniness and not minding being stepped on sometimes. Conversely, hikers will likely see quite different plants when they get a mile into the wilderness area
