It is not unheard of for bulbs or corms to be mislabeled; that is one possibility. So it may be nothing that you did! When you lift the bulbs this fall, you can inspect them for signs of disease. If they are soft and mushy, toss them.

Here are some links to refresh you on the care requirements and planting instructions:

When the plant is no longer green, it isn't nurturing the bulb any longer. So it is OK to cut it down. Glads are hardy to zone 7. North of that, it is necessary to dig up the bulbs in fall and store them in a cool, dry place until next spring. Mark where the bulbs are so you don't accidentally dig into them.

If the corms are too small (less than 3/4 inch) or unhealthy the plant will be unlikely to bloom. These articles should help:

This website has a lot of information on bulb storage and how long bulbs can be stored. Bleeding hearts are not technically a bulb and they are hardy through zone 3. Soak the root pieces in warm water for a couple of hours and plant them near the surface. Make sure to prepare the bed well as these perennials are long-lived and they spread. Bleeding heart prefers morning sun only. It will not do well in full sun which your other bulbs require. Blazing star, Liatris, is hardy zones 3-9 and can be put out now. Here is the link to storing the others:

I would keep a close eye on them come next January/Feb. This is an odd time of year for a bulb to go into storage. In my experience, some break dormancy before planting time arrives. If you see signs of life, pot up those bulbs.

Although it won't kill it, its very likely that they will be a little stunted next year. I think they will survive, though. Here is an article that will help: https://www.gardeningknowhow.com/ornamental/bulbs/gladiola/trimming-leaves-on-gladiolus.htm
