Re: Pinus pinnea Interesting that they can grow Stone Pine there. It really needs to be in zone 8 at least, preferably zone 9 to be reliable. It's only a young tree though (~15 years?), so may not yet have had a severe winter. It also looks rather thin, as if it is perhaps suffering from a needlecast disease with the high summer himidity.
This is a picture of a "spruce" I planted this spring for a friend of mine in north Seattle. In August I noticed the new growth was two-needle pine. I couldn't figure out what happened until someone identified it as Pinus picea, Italian stone pine. I never knew that pines had juvenile and adult leaves.
Yep, Pinus pinea is what you have! All pines have juvenile leaves like that, but most only produce it in their first year, there's only a handful of pines which keep it for several (3-5) years, of which Pinus pinea is one. Some others that also do so are P. canariensis, P. halepensis, P. pinaster, and all of the pinyon pines (P. edulis, P. monophylla, P. quadrifolia, etc.). Looks like yours is on a collision course with that Douglas-fir (left side, second pic)
