Hi,
This is frost/freeze damage. Most of Maryland was hit recently with low temperatures that damaged many of our landscape plants. Healthy plants should recover and put out new leaves, but it can take a few weeks. We have seen certain species like Hydrangea hit very hard from this. The holly and the mohonia must have just put out new growth that hadn't hardened off yet when the frost hit. The affected leaves will eventaully wither, dry up, and fall off.
In the meantime monitor for watering needs since the plants will need ample root moisture to produce new growth and we have in a sustained drought throughout Maryland due to insufficient rian fall since 2024.
