What are the tiny red bugs that have begun covering the stems of my bachelor buttons (Thinking they are what I planted, though the label said Pincushion!)? They are growing well at 8, 500′ in the Rocky Mountains of Colorado. Recently, tiny red bugs have attached themselves to some of the stems. It has been an unusually rainy year here. Also, the stems and leaves are now covered in a silvery powdery looking substance. The plants from last year did not return. Any tips to ensure that the ones planted this year will show up next year? Thanks! (P. S. Can’t find how to change my Zone, it is 4!)
My plants grow up prolifically then seem to collapse after flowering and a second very weak second blooming appears randomly among the plants. What am I doing wrong or what should I be doing to prevent the collapse and to encourage the second blooming?

Dead heading your Bachelor Buttons will encourage stronger stems and more flowers.
I planted the flower from seed, but the plant did not produce any flowers. Will it come back next spring?

There is a chance that there are still viable seeds laying around, but if it did not flower then it may not have seeded. If this is the case you will have to re-seed. Start them indoors earlier to ensure they reach full maturity.
If your bachelor button, aka cornflower, plants don't bloom, something is wrong unless you planted them late in the summer. They are annuals, vigorous bloomers and set so much seed that they are considered weedy. Too much fertilizer results in lush green growth and no flowers. Full sun, at least 6 hours, is necessary and plants don't tolerate wet soil. Did you notice any buds forming but not opening? There are several insects that destroy buds.
