Thank you for contacting Ask Extension. The problem I see on both of these plants are slug damage. It probably occurred a few months ago, and the browning around the holes indicate that. You can avoid slug damage on the sedum, if they were planted in full sun. It appears that it is planted mostly in shade. The hosta damage can be stopped if you pull some of the mulch away from the crown of the hosta, clean up debris around the plants and put out slug traps.

I have included several publications for your reference:
