Bert, you are going to have to wait and see
Some of what you planted may have successfully self-seeded and it will appear coming up through the mulch in spring. Some may not.
Without knowing what you planted, it is impossible to say much more than "watch and see". And even if you could tell us exactly what plants you had last year, there is no way to be certain as to how well they will do at coming back. Plants have a tendency to surprise us, both good and bad.
