The seeds look like this

Those conifers are common in the colder parts of the country, but I don't know their name. If you took a piece to a garden centre they'd probably be able to identify it for you.

Conifers are gymnosperms, they don't flower. They have male cones which produce pollen, and female cones in which the seeds develop. What you have are female cones. Because they've split there probably won't be any seed inside.
