Does sea holly dieback in winter?
When it comes to wintertime, sea holly will die back until the early spring. This is very normal for sea holly, and as long as its soil has good drainage, you should see it return when the weather warms up. With that said, make sure to trim down your plant, only leaving evergreen sections before the winter season.
How do you take care of a sea holly plant?
Eryngiums need plenty of sunshine and free-draining soil. They can tolerate poor soil, and a spot at the foot of a wall is a good position as the soil will remain dry over winter. It's also a good idea to plant eryngiums away from the edge of a border or path, as their spikes can be quite sharp.
