Sweet alyssum has been a favorite of mine since childhood. It is super easy to grow and the fragrance really is sweet. Also, in Seattle, this plant survives the winter and actually looks even better as a groundcover or pot plant the second year.
I don’t grow this plant all that often, but it is a fun filler for patio pots and garden beds. I had a leftover alyssum in a pot that survived the winter and is now blooming like mad in the driveway bed.
I might try to take some cuttings early next spring to increase my stock and plant them around in pots and beds as needed next year.
