Names of perrenials are Peppermint Star Dianthus and Christy Veronica

Were the plants OUTDOORS when u bought them? If not, perhaps it's just shock from changing temps.

Could also be too much OR not enough water. Did u water thoroughly WHEN U PLANTED? Maybe the water's not reaching the roots or perhaps the root ball was dry when u planted?

Could also be just an initial droop from being transplanted. Sometimes perennials are slower to "show" new growth (takes awhile to acclimatize)

Do not dispair! :D

hi Acfurino

Stop watering the perinnials so much....it is not good for them.mother nature will take care of that..unless there is no rain for some time...an inch a week is good..
and a little fertilizer is ok also..

cheers and good luck

I agree with diggy, especially if you have been getting rain every day or so. If that's the case, you don't need to water.

Hi all, are the leaves otherwise healthy? Aside from transplant shock, it's also possibly the overapplication of miracle gro which contains chemical fertilizers which can be too much and cause root burns. If the leaves are healthy, there's nothing wrong with the plants. You would probably be seeing a natural thing with the flowers simply turning brown as in most dianthus around mid June. Consider too the many of these perennials (BTW - this is the right spelling), are started early in the process and therefore bloom earlier than what should be around this time of the year. In order for sellers to attract people to buy these plants, they would need them to bloom earlier. This is usually good for people who are not so familiar with plants and may not know what the blooms like.

I tend to agree with ianna. When first i read "Miracle Grow", I cringed. You must remember that you are dealing with young/baby plants. As such, their root systems are not equipped to use such additives yet. Also, your soil with built in water retainers, might be holding too much water... thereby not allowing oxygen to be taken up by the young roots.
If it were me, I'd gently lift a few of the affected plants out of the soil, and examine their roots. See if the roots are mushy, dark and slimy ...OR ... are they dry and still in the same square shape, as when you planted them.
Best of luck ...let us know what you find
