Weed or desirable plant?
Georgetown Lutheran Church would appreciate your help determining if plants in our garden are weeds or desirable. (Our gardener has departed.) If desirable, a web address describing proper care would be fantastic. Thank you for this service!

1. Looks like Siberian iris. https://www.gardeningknowhow.com/ornamental/bulbs/iris/growing-siberian-iris.htm You do not need to cut back the old foliage. Let it be a mulch for itself.
2. One of the many salvias. Send us photos when it blooms, and we can be more helpful.
3. Plumbago, a groundcover perennial. http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=b960
