Can we have a geographical location, please?

Never heard of Lamb Kill but Google tells me it's Kalmia. I don't know that plant at all well.

Could be Kalmia angustifolia--lambkill is one of its common names.

I agree with Laceyvail that it's Kalmia angustifolia (which In New England has the common name of sheep laurel.) Both the old leaves and the new leaves look right, and the leaf arrangement that is a combination of opposite and whorls is right.
