Gordons Ornamec Over-The-Top Grass Herbicide is a great choice for treatment of grassy weeds in established ornamental beds. Many of the plants you have listed are on the "full tolerant" species list on the product label. For those not listed, you may want to test a small number of plants or avoid spraying over the top of thos plants.
To control grass in ornamentals or landscaped areas, you will need to use 2.5 oz of Gordons Ornamec Over-The-Top Grass Herbicide + 1/3 oz. of a nonionic surfactant per gallon of water. Please refer to the product label for complete application instructions.
Bermuda would be considered a grassy weed, so you need a product that is geared towards grassy weeds and not broadleaf weeds. We want to be clear that bermuda can be suppressed, but it is VERY difficult to kill completely. It will take multiple treatments to finally kill it. But Fusilade II is usually the go to product for this issue.
This is directly off of the product label:
Apply 0.07-0.14 oz/1000 sq. ft. (3-6 oz./A) along with 0.25% v/v (1/2 pt./25 gals.) of a nonionic surfactant. Application should be made every 28 days when the grass weeds are actively growing. The higher rates may result in temporary discolorization of the desirable turf with recovery in 10-14 days. Do not apply to desirable turf which is under stress. For best results, make applications in spring and fall and avoid treatments during July and August.
Complete control of undesirable grass may take 1-2 growing seasons.
Gordons Ornamec Over the Top Grass Herbicide can be used along with a surfactant in Tall Fescue lawns to control Bermuda. Applications should not be made in the hot summer months. The first application should be made in April/May and second application in September/October. Please refer to page 2 of the product label for details on this application to your lawn.

Yes, Gordons Ornamec Over-The-Top Grass Herbicide will kill St. Augustine turf. Unfortunately, because Bermuda and St. Augustine grasses are closely related, there is not really a product that will remove the Bermuda without also harming the St Augustine. We recommend that you spot treat the Bermuda as much as possible with a non-selective glyphosate product and then replant with St. Augustine in those areas in a couple of weeks when the Bermuda is gone. .
You can use a grass killer such as Gordons Ornamec Over-The-Top Grass Herbicide to kill johnsongrass around established daylilies. Ornamec will control Annual Johnsongrass seedlings (sorghum halepense) when 2 to 8 inches tall, before tillering or heading. It will control perennial rhizome johnsongrass that is 8 to 18 inches tall and before booted stage, per the product label. You may need multiple applications for more mature plants. We also suggest using a pre-emergent herbicide in the future for the best control of Jonhsongrass and many other difficult weeds. Prodiamine 65 WDG is safe to use around most turf and ornamentals.
No, Gordons Ornamec Over-The-Top Grass Herbicide is not safe to use in St. Augustine grass. Bermuda grass is so closely related to St. Augustine grass that there is nothing that will remove Bermuda from St. Augustine and not hurt the St Augustine as well. In your situation it is recommended to spot treat the Bermuda with a non-selective glyphosate product and kill it directly, and then replant St. Augustine in those areas.
Gordons Ornamec Over-The-Top Grass Herbicide is best applied to bermuda in the spring as it is just starting to green up usually and in the fall when it is about to go into dormancy as directed on page 2 of the product label.

Gordons Ornamec Over-The-Top Grass Herbicide lists daylilies and Lily of the Nile as tolerable but none of the other ones.
