I planted a sea holly last year and it did really well with lots of blooms. Cut down to ground in winter as advised but it has not regrown this year. What could be the reason for this?

The stems are generally cut back in the fall, but leaving the evergreen leaves on the plant is recommended. These leaves help feed the roots.
Certainly give it some more time to see if the plant can grow back from the roots.
Many times I have though I'd lost a plant only to find tiny signs of life well into the growing season.
