Meyers Garden Center, Hanna’s Garden Shop, and Warren Family Garden Center should be good sources. But, I would call first to make sure they have some that have not over wintered in their greenhouses

It is perfectly fine to shape them and I would do it asap.
After reviewing the product label, I would think you would risk herbicide damage on perennials. Daylilies however was on the approved applications list. If you decide to risk it try a small area and see if it damages your plants.

On a very steep slop in shade many ground covers will work but getting them established without causing the bank to erode can be a big problem. Probably the most vigorous on for this type of situation is English ivy and you can by it as sprigs from many nurseries. Others that work would be monkey grass and liriope. They can also be purchased in 4-inch pots. A little used ground cover for this type slope is the small leafed periwinkle (Vinca minor) as it roots when the stems touch the ground like ivy but is hard to find. Probably if you use Vinca you will have to have a friend to give you some. Be sure you plant each pots well and if the soil on your slope is poor amend the soil, mulch with pine straw when planted to prevent erosion. Watering the first year of establishment is a must.
Checking with herbicide specialist. Will get back to you- john
Update- the expert says atrazine
From bud set to bloom is 6-8 weeks. So the later you pinch them back the later they bloom. Most years we do not have frost before early November, so it just depends when you want them to bloom as to when you do your last pinch. Plan on 10-12 weeks after pinching before blooms show color.
While 2,4,D will not kill Centipede and St Augustine it may injure it. So it is up to you,but if dormant it will have less chance of injury.
You know I have had them in my yard and sever winters they were killed back. Saying that, the quick freeze we had recently where the temperature was down to 18 degrees really is very damaging to plants like loquat that are at there upper limits of their hardiness. If you do decide to plant I would make sure it is in a protected location
