My side yard, which I can see from my bathroom window, suddenly was a beautiful mat of tiny blue flowers. They lasted most of the month of April, each tiny flower lasting only one day. That was 3 or 4 years ago. I IDed the plant as an invasive creeper named Commelina communis (Asiatic Dayflower). The blue color of the flowers is caused by a 3-D complex of plant chemicals & magnesium that absorbs the red part of sun light & reflects the blue.
I've thought about the decline in the flowering & I've come to the conclusion that the beautiful flower mat I had seen that first year can't form as richly as before because that first & later blooms used up most of the magnesium found in my yard's soil. My lawn service vacuums up loose grass clippings, so little magnesium from old flowers gets to leach back into the soil. No magnesium, no blue flowers. The probable answer: feed that area of my lawn with inexpensive Epsom Salts (magnesium sulfate). Mixed with 10-10-10 fertilizer. And the sulfate ion makes the soil acid, which this plant loves. I'm only looking at something under 500 square feet to be treated. One of my friends is in the tree business so he would know who in the area could handle a small job like that.
The proof of my hypothesis: blue flowers next April.
