If you are referring to Agapanthus (called African Lily or more commonly, Lily-of-the-Nile), these are perennial plants, though they are marginally winter hardy in Maryland. Wet soils and cold winters typically cause losses among these plants; your area being a bit more moderated in temperature and sandier in soil type may be conditions allowing them to spread successfully, though it is uncommon.
If digging them up has not been not successful, you can try a non-selective systemic herbicide, though it may need to be mixed with a adjuvant (also called spreader-sticker or surfactant). The waxy leaves of plants like Agapanthus can fail to absorb enough of the herbicide otherwise; the spreader-sticker serves to help the herbicide mix to stick to the leaf long enough to soak in. Non-selective herbicides can damage any plant they come in contact with, so use caution in spraying. One method to avoid accidental exposure is to either shield other plants with something (like cardboard) while spraying, or to use an inexpensive paintbrush or foam brush (such as from a home improvement store) to paint the herbicide onto the leaves. Systemic herbicides are absorbed by the foliage to be moved down into the roots in order to kill the entire plant. Whichever formulation you use, follow label instructions and do not pull up or cut the plants after spraying to give the herbicide time to work. Spreader-sticker brands will also give you instructions on the label on how much to add to your herbicide sprayer. How long control takes will depend on the chemical, the plant's stage of growth, and weather. Once the foliage is browned and drying, the roots can be considered dead and the plant can be removed (or the leaves cut off if you do not want to dig).
