-
on open, grassy, undulating plain in basin along & below eastern Madrean escarpment, among diverse grasses and forbs on coarse volcanic alluvium.
-
Plants in grasses on reddish volcanic rhyolite of on grassy, moderate hillside slope with Dahlia scherffii, Salvia emaciata, Verbena pinetorum, Milla biflora. Note short beak & 3 near equal petals. Original ID as C. coelestis, which is now considered a synonym under C. tuberosa
-
-
along drainage course between low limestone hills in open flat of disturbed calcareous soil and gravel outwash as road bisects small arroyo; with Ibervillea, Lantana, Cyphomeris, Rivina and Hunnemannia
-
roadside drainage in grasses on volcanic tuff of grassy hillside. Species is difficult to distinguish from C. tuberosa and maybe conspecific

Slo.: navadna komelina - syn.: Commelina debilis Ledeb - Habitat: roadside, sandy, almost flat ruderal terrain, in half shade, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 450 m (1.500 feet), alpine phytogeographical region. - Substratum: sandy soil. - Comment: This beautiful and exotic looking introduced annual creeper originates in Asia. It is presently slowly occupying Bovec basin. I saw it the first time a few years ago. Today one can find it on several ruderal places in and around Bovec town. It is easily recognizable by its beautiful, bilaterally symmetrical, deep blue flowers, which cannot be overlooked. So I am pretty sure the current spreading I see is real. It seems to be a relatively recent 'supplement' to local flora. Fortunately, for the time being, it doesn't seem particularly invasive. - It is introduced also to North America, where it is considered a common and sometimes troublesome weed in several cultures including soybean, cotton, rice, peanuts and others. Allegedly each flower blooms during the morning for a single day, hence the common name. Of cause, this should not be taken too literally. - Ref.: (1) A.Martini et all., Mala Flora Slovenije, Tehnina Zaloba Slovenije (2007) (in Slovene), p 711.
