My bedding plants of Alyssum are all brown from last year. Do I need to cut them right back now or just leave them to start their regrowth cycle?

Did you grow the annual Sweet Alyssum? Your expired plants will not return as a perennial, they have lived their lifespan and should be removed.
Here is a link with more information.
If you planted the perennial Basket-Of-Gold Alyssum, which is a perennial, you can trim the dead portions away and the plants will began to grow when the weather and soil warms.
